From 749b7fbd462e01ae73f9978ba73fa091bb20b063 Mon Sep 17 00:00:00 2001 From: Moritz Angermann Date: Fri, 5 Sep 2025 10:43:55 +0900 Subject: [PATCH 001/135] Conditionalize the ghc-internal dependency on the ghc version. This change reverts part of !14544, which forces the bootstrap compiler to have ghc-internal. As such it breaks booting with ghc 9.8.4.

This field is used by '-static-external' to conditionally use '-l:foo.a' syntax during linking, which is more robust than trying to find the absolute path to an archive on our own. * Adds a switch '-fully-static' that is meant as a high-level interface for e.g. cabal. This also honours 'extra-libraries-static'. This also attempts to clean up the confusion around library search directories. At the moment, we have 3 types of directories in the package database format: * library-dirs * library-dirs-static * dynamic-library-dirs However, we only have two types of linking: dynamic or static. Given the existing logic in 'mungeDynLibFields', this patch assumes that 'library-dirs' is really just nothing but a fallback and always prefers the more specific variants if they exist and are non-empty. Conceptually, we should be ok with even just one search dirs variant. Haskell libraries are named differently depending on whether they're static or dynamic, so GHC can conveniently pick the right one depending on the linking needs. That means we don't really need to play tricks with search paths to convince the compiler to do linking as we want it. For system C libraries, the convention has been anyway to place static and dynamic libs next to each other, so we need to deal with that issue anyway and it is outside of our control.

Sylvain Henry Date: Mon, 27 Oct 2025 15:39:33 +0100 Subject: [PATCH 027/135] Build external interpreter program on demand (#24731) This patch teaches GHC how to build the external interpreter program when it is missing. As long as we have the `ghci` library, doing this is trivial so most of this patch is refactoring for doing it sanely.

This simplifies the code significantly, particularly for the nand operation which previously required extensive workarounds for compiler compatibility issues. Changes: - Replace __sync_fetch_and_{add,sub,and,or,xor} with __atomic_fetch_* - Replace __sync_fetch_and_nand with __atomic_fetch_nand - Remove CAS-based fallback for nand operations - Remove compiler-specific warning suppressions for -Wsync-nand - Remove volatile qualifiers (not needed with __atomic builtins) - Update comments to reflect modern atomics usage All operations maintain __ATOMIC_SEQ_CST memory ordering for sequential consistency, matching the original behavior.

I can only theorize that this test isn't run in upstream's CI, because they don't build a static GHC. The culprit is that we go through the thin archive, trying to follow the members on the filesystem, but don't re-identify the new object format of the member. This pins `object_fmt` to `NotObject` from the thin archive.

Since gc_threads are allocated with stgMallocAlignedBytes (which doesn't zero memory), these fields contained garbage values. The initialization must be in new_gc_thread(), not init_gc_thread(), because: 1. new_gc_thread() is called once when a gc_thread is first allocated 2. init_gc_thread() is called at the START of each GC cycle 3. stat_startGC() sets the timing fields BEFORE init_gc_thread() is called 4. If we initialize in init_gc_thread(), we would reset the values that stat_startGC() just set, breaking the timing calculations The garbage values caused wild statistics like: gc_elapsed_ns=50426020081527 (14 hours of supposed GC time!) exit_elapsed_ns=18446741672370457118 (~= -1.3 billion as unsigned) These were being accumulated into stats and causing all productivity calculations to fail with massively negative values. --- rts/sm/GC.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/rts/sm/GC.c b/rts/sm/GC.c index 5a47e7f20f91..64d474980555 100644 --- a/rts/sm/GC.c +++ b/rts/sm/GC.c @@ -1186,6 +1186,16 @@ new_gc_thread (uint32_t n, gc_thread *t) t->free_blocks = NULL; t->gc_count = 0; + // Initialize timing fields to zero to avoid garbage values in stats. + // These are set properly in stat_startGC/stat_startGCWorker before use. + // Must be done here (not in init_gc_thread) because init_gc_thread is + // called at the start of each GC cycle AFTER stat_startGC sets these. + t->gc_start_cpu = 0; + t->gc_end_cpu = 0; + t->gc_sync_start_elapsed = 0; + t->gc_start_elapsed = 0; + t->gc_end_elapsed = 0; + init_gc_thread(t); for (g = 0; g < RtsFlags.GcFlags.generations; g++) From 1d7b991c4506e63181174009bbcbe93da323e833 Mon Sep 17 00:00:00 2001 From: Moritz Angermann Date: Mon, 8 Dec 2025 10:53:06 +0900 Subject: [PATCH 033/135] rts: Add stgCallocAlignedBytes with zeroing semantics Introduce stgCallocAlignedBytes as a zeroing aligned allocator, replacing stgMallocAlignedBytes.

Key fixes: 1. Detect data vs code references in X86_64_ELF_NONPIC_HACK (Elf.c) - The jump island mechanism was incorrectly applied to data references - For info table pointers (_con_info symbols), embedding a jump island address caused GC crashes ("strange closure type") - Now distinguishes R_X86_64_PLT32 (code) from R_X86_64_PC32 (data) - Data references use GOT-style indirection through extra->addr instead 2. Preserve dlerror for linker script fallback handling (LoadNativeObjPosix.c) - dlerror() clears after first call, losing error context - Now saves error string before retry logic - Fixes misleading error messages when loading fails 3. Promote boot libraries to RTLD_GLOBAL for dynamic code loading (RtsStartup.c) - Boot libraries loaded with RTLD_LOCAL weren't visible to dlsym - Dynamic object loading failed to resolve symbols from boot libs - Now re-opens boot libraries with RTLD_GLOBAL flag at startup 4. Skip loading libc/libm already linked into process (LoadNativeObjPosix.c) - Avoids redundant loading and symbol conflicts - Checks if library is already resident before calling dlopen 5. Dynamic lookup of stg_interp_constr entry points via dlsym (RtsSymbols.c) - Interpreter constructor symbols need runtime resolution - Adds dynamic fallback when static symbols unavailable 6. Remove residual debug instrumentation - Cleans up debugging code from Evac.c and LoadNativeObjPosix.c --- rts/RtsStartup.c | 179 ++++++++++++++++++++++++++++++++ rts/RtsSymbols.c | 1 + rts/linker/Elf.c | 98 +++++++++++++---- rts/linker/LoadNativeObjPosix.c | 18 +++- 4 files changed, 277 insertions(+), 19 deletions(-) diff --git a/rts/RtsStartup.c b/rts/RtsStartup.c index e9a5b6d44b3e..c66fbe64c19f 100644 --- a/rts/RtsStartup.c +++ b/rts/RtsStartup.c @@ -6,6 +6,12 @@ * * ---------------------------------------------------------------------------*/ +/* _GNU_SOURCE needed for RTLD_NOLOAD on some Linux/glibc configurations. + * Must be defined before any headers are included. */ +#if !defined(mingw32_HOST_OS) && !defined(_GNU_SOURCE) +#define _GNU_SOURCE +#endif + #include "Rts.h" #include "RtsAPI.h" #include "HsFFI.h" @@ -70,6 +76,173 @@ #include #endif +/* + * Note [Promoting Boot Libraries to RTLD_GLOBAL] + * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + * Boot libraries (ghc-internal, RTS) are loaded by the system linker at + * program startup with RTLD_LOCAL (default).

Previously these were emitted inline in Wasm.S for every compilation unit, which conflicted with PIC shared-library builds (WayDyn) that GHCi uses. This commit moves the GlobalRegs declarations into a dedicated assembly file (rts/wasm/WasmGlobalRegs.S) that is compiled on-demand by mkWasmGlobalRegsObj in GHC.Linker.Executable only when linking a final executable, not for shared libraries. Key changes: - compiler/GHC/Linker/Executable.hs: add mkWasmGlobalRegsObj; look up WasmGlobalRegs.S via unitDataDir from the rts package; compile with clang using uppercase .S suffix so CPP preprocessing runs - rts/wasm/WasmGlobalRegs.S: new file with .globaltype declarations using i32 directly (no CPP macros, WASM32-only) - rts/wasm/Wasm.S: remove GlobalRegs declarations (moved to WasmGlobalRegs.S) - compiler/GHC/Platform/Ways.hs: document that WayDyn enables PIC which is required for WASM GHCi/TH shared library loading --- compiler/GHC/Linker/Executable.hs | 64 +++++++++ compiler/GHC/Platform/Ways.hs | 6 +- rts/wasm/Wasm.S | 204 ++++++--------------------- rts/wasm/WasmGlobalRegs.S | 222 ++++++++++++++++++++++++++++++ 4 files changed, 330 insertions(+), 166 deletions(-) create mode 100644 rts/wasm/WasmGlobalRegs.S diff --git a/compiler/GHC/Linker/Executable.hs b/compiler/GHC/Linker/Executable.hs index 50e9a1cfc534..d13fc21a492b 100644 --- a/compiler/GHC/Linker/Executable.hs +++ b/compiler/GHC/Linker/Executable.hs @@ -29,6 +29,8 @@ import GHC.Utils.Outputable as Outputable import GHC.Utils.Logger import GHC.Utils.TmpFs import GHC.Data.FastString +import GHC.Data.ShortText qualified as ST +import GHC.Types.SrcLoc (noSrcSpan) import GHC.Driver.Session import GHC.Driver.DynFlags @@ -205,6 +207,7 @@ linkExecutable logger tmpfs opts unit_env o_files dep_units = do extraLinkObj <- maybeToList <$> mkExtraObjToLinkIntoBinary logger tmpfs opts unit_state noteLinkObjs <- mkNoteObjsToLinkIntoBinary logger tmpfs opts unit_env dep_units + wasmGlobalRegsObj <- maybeToList <$> mkWasmGlobalRegsObj logger tmpfs opts unit_env let (pre_hs_libs, post_hs_libs) @@ -297,6 +300,7 @@ linkExecutable logger tmpfs opts unit_env o_files dep_units = do ++ pkg_lib_path_opts ++ extraLinkObj ++ noteLinkObjs + ++ wasmGlobalRegsObj -- See Note [RTS/ghc-internal interface] -- (-u must come before -lghc-internal...!) ++ (if ghcInternalUnitId `elem` map unitId pkgs @@ -442,6 +446,66 @@ mkNoteObjsToLinkIntoBinary logger tmpfs opts unit_env dep_packages = do else Outputable.empty ] +-- | Compile WASM GlobalRegs on-demand for executable linking +-- +-- WASM executables (both static and dynamic) need STG GlobalRegs injected +-- at link time.

The assembler treats any symbol with a .functype as a WASM function, which conflicts with wasm-ld when the same symbol is defined as data elsewhere. Fix: exclude symbols that are purely in data sections from .functype emission. 2. .size emission: the LLVM assembler rejects .size for WASM function symbols (post Aug 2025 change, abacb164). Fix: always emit .size for data section symbols (safe), and rely on the .functype exclusion above to keep info table symbols data-typed so their .size directives are also valid. --- compiler/GHC/CmmToAsm/Wasm/Asm.hs | 18 +++++++++++++++++- 1 file changed, 17 insertions(+), 1 deletion(-) diff --git a/compiler/GHC/CmmToAsm/Wasm/Asm.hs b/compiler/GHC/CmmToAsm/Wasm/Asm.hs index 392ab34b7fbd..13d59315f220 100644 --- a/compiler/GHC/CmmToAsm/Wasm/Asm.hs +++ b/compiler/GHC/CmmToAsm/Wasm/Asm.hs @@ -188,6 +188,12 @@ asmTellDataSection ty_word def_syms sym DataSection {..} = do when (getUnique sym `memberUniqueSet` def_syms) $ asmTellDefSym sym asmTellSectionHeader sec_name asmTellAlign dataSectionAlignment + -- The LLVM WASM assembler requires .size for every data symbol.

Key changes: 1. Make Opt_ExternalDynamicRefs default on all PIC platforms (DynFlags.hs) - Previously only enabled for specific configurations - Dynamic builds require external dynamic references for proper GOT usage - Prevents relocation issues with large code models 2. Pipeline and session handling updates - Driver/Pipeline.hs: Handle dynamic linking in compilation pipeline - Driver/Session.hs: Session configuration for dynamic builds - Driver/Flags.hs: Flag handling for dynamic mode 3. Linker updates for dynamic mode - Linker/Executable.hs: Executable linking for dynamic builds - Linker/Static.hs: Static linking coordination - ByteCode/Linker.hs: Bytecode linker for dynamic interpreter 4. Unit state and GHCi support - Unit/State.hs: Package database handling for dynamic libs - GHCi/InfoTable.hsc: Info table generation for dynamic mode - Tc/Gen/Splice.hs: Template Haskell splice handling --- compiler/GHC/ByteCode/Linker.hs | 51 ++++++++++++++---- compiler/GHC/Driver/DynFlags.hs | 18 ++++--- compiler/GHC/Driver/Flags.hs | 1 + compiler/GHC/Driver/Session.hs | 5 ++ compiler/GHC/Linker/Executable.hs | 35 +++++++++++++ compiler/GHC/Linker/Loader.hs | 50 +++++++++++++----- compiler/GHC/Linker/Static.hs | 5 +- compiler/GHC/Runtime/Interpreter/C.hs | 10 +++- compiler/GHC/Unit/State.hs | 75 ++++++++++++++++++++++++++- libraries/ghci/GHCi/InfoTable.hsc | 56 +++++++++++++------- rts/include/stg/MiscClosures.h | 19 +++---- 11 files changed, 260 insertions(+), 65 deletions(-) diff --git a/compiler/GHC/ByteCode/Linker.hs b/compiler/GHC/ByteCode/Linker.hs index 60e0d7792d35..aeb921a31a94 100644 --- a/compiler/GHC/ByteCode/Linker.hs +++ b/compiler/GHC/ByteCode/Linker.hs @@ -190,26 +190,57 @@ resolvePtr interp pkgs_loaded le lb bco_ix ptr = case ptr of withForeignRef (expectJust (lookupModuleEnv (breakarray_env lb) tick_mod)) $ \ba -> pure $ ResolvedBCOPtrBreakArray ba +{- +Note [Symbol lookup order for boot libraries] +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +When looking up symbols for bytecode linking, we must check the main program's +symbol table BEFORE looking in dynamically loaded libraries.

Key changes: 1. RTS sublibrary infrastructure (rts/rts.cabal) - Define separate sublibraries for RTS components - Add proper library dependencies and visibility - Configure shared library generation for RTS parts 2. Configure support for dynamic builds (rts/configure.ac) - Detect platform-specific dynamic linking requirements - Set appropriate linker flags for each sublibrary - Handle symbol visibility for exported functions 3. API updates for sublibrary boundaries (rts/include/RtsAPI.h) - Adjust exported symbol declarations - Ensure proper visibility across sublibrary boundaries 4. AutoApply support for interpreter (rts/AutoApply*.cmm) - Add AutoApply.cmm and vector variants (V16, V32, V64) - Required for dynamic bytecode interpreter operation 5. Cabal project configuration - cabal.project.stage1: Add no-ghc-internal flag for stage1 builds - cabal.project.stage2: Configure full RTS with all sublibraries 6.

Test infrastructure (boilerplate.mk) - Configure tests for dynamic linking environment - Set proper library paths for test execution 3. Test adjustments for RTS split - T18072debug: Update grep to match cabal-based RTS naming - T23142.hs: Revert module name to fix -Di debug output test - keep-cafs-fail.stdout: Update expected output 4. Dynamic linking test updates - ghci/linking/dyn/all.T: Adjust for dynamic GHC - T2228: Restore expect_broken(7298) for dynamic builds - T11531.stderr: Update expected error messages 5. Platform-specific adjustments - T10458: Skip on musl with dynamic GHC - T11223 tests: Update stderr expectations for Windows 6. Test configuration - .gitignore: Add patterns for dynamic test artifacts - dynlibs/Makefile: Update for dynamic build testing - perf/size/all.T: Adjust size expectations --- testsuite/.gitignore | 4 ++ testsuite/driver/testlib.py | 67 ++++++++++++++++++-------- testsuite/mk/boilerplate.mk | 15 +++++- testsuite/tests/dynlibs/Makefile | 2 +- testsuite/tests/ghci/linking/dyn/all.T | 23 +++++++++ testsuite/tests/perf/size/all.T | 4 +- 6 files changed, 92 insertions(+), 23 deletions(-) diff --git a/testsuite/.gitignore b/testsuite/.gitignore index 2c699cf04625..65095f055660 100644 --- a/testsuite/.gitignore +++ b/testsuite/.gitignore @@ -60,6 +60,10 @@ tmp.d *.so *bindisttest_install___dir_bin_ghc.mk *bindisttest_install___dir_bin_ghc.exe.mk +mk/*_ghcconfig*_bin_ghc*.mk +mk/*_ghcconfig*_bin_ghc*.exe.mk +mk/*_ghcconfig*_test___spaces_ghc*.mk +mk/*_ghcconfig*_test___spaces_ghc*.exe.mk mk/ghcconfig*_bin_ghc*.mk mk/ghcconfig*_bin_ghc*.exe.mk mk/ghcconfig*_test___spaces_ghc*.mk diff --git a/testsuite/driver/testlib.py b/testsuite/driver/testlib.py index 9651ee439fa6..eb982ed1ecb2 100644 --- a/testsuite/driver/testlib.py +++ b/testsuite/driver/testlib.py @@ -663,7 +663,19 @@ def collect_size ( deviation, path ): return collect_size_func(deviation, lambda: path) def collect_size_func ( deviation, path_func ): - return collect_generic_stat ( 'size', deviation, lambda way: os.path.getsize(in_testdir(path_func())) ) + # Wrap path resolution to avoid passing None/invalid paths to Path APIs. + def current(_way): + p = path_func() + if p is None: + raise StatsException("No path returned for size collection") + # If p looks absolute, use it directly; else resolve relative to testdir + pth = Path(p) + if not pth.is_absolute(): + pth = in_testdir(p) + if not pth.exists(): + raise StatsException(f"Path not found for size collection: {pth}") + return os.path.getsize(pth) + return collect_generic_stat ( 'size', deviation, current ) def get_dir_size(path): total = 0 @@ -676,7 +688,7 @@ def get_dir_size(path): total += get_dir_size(entry.path) return total except FileNotFoundError: - print("Exception: Could not find: " + path) + raise StatsException(f"Directory not found for size collection: {path}") def collect_size_dir ( deviation, path ): return collect_size_dir_func ( deviation, lambda: path ) @@ -708,7 +720,12 @@ def collect_size_ghc_pkg (deviation, library): # same for collect_size and find_so def collect_object_size (deviation, library, use_non_inplace=False): if use_non_inplace: - return collect_size_func(deviation, lambda: find_non_inplace_so(library)) + try: + return collect_size_func(deviation, lambda: find_non_inplace_so(library)) + except Exception as _: + # should we fail to find inplace, let's try to find non-inplace. + # FIXME: remove the whole inplace nonsense outright. + return collect_size_func(deviation, lambda: find_so(library)) else: return collect_size_func(deviation, lambda: find_so(library)) @@ -725,21 +742,20 @@ def path_from_ghcPkg (library, field): try: result = subprocess.run(ghcPkgCmd, capture_output=True, shell=True) - # check_returncode throws an exception if the return code is not 0. result.check_returncode() - - # if we get here then the call worked and we have the path we split by - # whitespace and then return the path which becomes the second element - # in the array - return re.split(r'\s+', result.stdout.decode("utf-8"))[1] + out = result.stdout.decode("utf-8").strip() + # Expected format: ": " possibly spanning lines; grab text after first colon. + m = re.split(r"^\s*[^:]+:\s*", out, maxsplit=1, flags=re.MULTILINE) + if len(m) == 2: + val = m[1].strip().splitlines()[0].strip() + if val: + return val + raise StatsException(f"ghc-pkg returned no {field} for {library}.

This reduces C compiler invocations from hundreds/thousands per .hsc file to just 1-2 total by batching all constant-like directives (#const, #size, #alignment, step with graceful fallback to per-directive compilation. Key changes in the fork (bf966e8): - Batch collection of all batchable directives with conditional stack tracking - Single C file generation with all constants as global variables - Assembly parsing via ATTParser to extract all values at once - Graceful try/catch around ATT.parse for compilers producing non-AT&T assembly (e.g. emcc for WebAssembly), falling through to per-directive path - --no-batch flag for debugging/fallback Performance impact per .hsc file: - Before (non-via-asm): ~28 compilations per directive (e.g. 4089 for Flags.hsc) - Before (via-asm): 1 compilation per directive (e.g. 147 for Flags.hsc) - After (batch): 2 compilations total per file (validity check + batch) Fork: https://github.com/stable-haskell/hsc2hs/tree/feat/batch-cross-compilation * fix: update hsc2hs fork with Windows CodeView debug section fix Update hsc2hs fork reference to include fix for ATT parser crash on Windows where Clang emits CodeView .debug$S sections even with -g0. The parser now filters out debug sections and handles unrecognized instruction patterns gracefully. --- cabal.project.stage2 | 138 ++++++++++++++++++++++++------------------- 1 file changed, 76 insertions(+), 62 deletions(-) diff --git a/cabal.project.stage2 b/cabal.project.stage2 index eb8d5378917f..c9cd690f7872 100644 --- a/cabal.project.stage2 +++ b/cabal.project.stage2 @@ -1,10 +1,14 @@ --- Configuration common to all stages -import: cabal.project.common -import: cabal.project.stage2.settings +allow-boot-library-installs: True +benchmarks: False +tests: False -- Disable Hackage, we explicitly include the packages we need. active-repositories: :none +-- Import configure/generated feature toggles (dynamic, etc.) if present. +-- A default file is kept in-tree; configure will overwrite with substituted values. +import: cabal.project.stage2.settings + packages: -- RTS rts-headers @@ -38,15 +42,44 @@ packages: utils/ghc-iserv utils/ghc-pkg utils/ghc-toolchain - utils/haddock - utils/haddock/haddock-api - utils/haddock/haddock-library utils/hp2ps utils/runghc utils/unlit + utils/haddock + utils/haddock/haddock-api + utils/haddock/haddock-library -- The following are packages available on Hackage but included as submodules - -- https://hackage.haskell.org/package/hsc2hs-0.68.10/hsc2hs-0.68.10.tar.gz + libraries/array + libraries/binary + libraries/bytestring + libraries/Cabal/Cabal + libraries/Cabal/Cabal-syntax + libraries/containers/containers + libraries/deepseq + libraries/directory + libraries/exceptions + libraries/file-io + libraries/filepath + libraries/haskeline + libraries/hpc + libraries/libffi-clib + libraries/mtl + libraries/os-string + libraries/parsec + libraries/pretty + libraries/process + libraries/semaphore-compat + libraries/stm + libraries/terminfo + libraries/text + libraries/time + libraries/transformers + libraries/unix + libraries/Win32 + libraries/xhtml + utils/hpc + -- hsc2hs: see source-repository-package below https://hackage.haskell.org/package/Win32-2.14.2.1/Win32-2.14.2.1.tar.gz https://hackage.haskell.org/package/array-0.5.8.0/array-0.5.8.0.tar.gz @@ -84,55 +117,6 @@ packages: https://hackage.haskell.org/package/happy-2.1.5/happy-2.1.5.tar.gz https://hackage.haskell.org/package/happy-lib-2.1.5/happy-lib-2.1.5.tar.gz --- wip/andrea/local-store -source-repository-package - type: git - location: https://github.com/stable-haskell/Cabal.git - tag: d7bf2ce3f9a7da4640833ddc5bb7740d2557b6a7 - subdir: Cabal - Cabal-syntax - -source-repository-package - type: git - location: https://github.com/stable-haskell/hpc-bin.git - tag: 5923da3fe77993b7afc15b5163cffcaa7da6ecf5 - -if !os(windows) - packages: - https://hackage.haskell.org/package/terminfo-0.4.1.7/terminfo-0.4.1.7.tar.gz - -allow-newer: hsc2hs:* - , Win32:* - , array:* - , binary:* - , bytestring:* - , containers:* - , deepseq:* - , directory:* - , exceptions:* - , file-io:* - , filepath:* - , haskeline:* - , hpc:* - , libffi-clib:* - , mtl:* - , os-string:* - , parsec:* - , pretty:* - , process:* - , semaphore-compat:* - , stm:* - , terminfo:* - , text:* - , time:* - , transformers:* - , unix:* - , xhtml:* - -if !os(windows) - package * - library-for-ghci: True - -- -- Constraints -- @@ -148,8 +132,28 @@ constraints: -- Package level configuration -- +package haddock-api + flags: +in-ghc-tree + +if !os(windows) + packages: + libraries/terminfo + +package * + library-vanilla: True + -- shared/executable-dynamic now controlled by Makefile (DYNAMIC variable) + -- so we do not pin them here; default (static) remains when DYNAMIC=0. + executable-profiling: False + executable-static: False + +if !os(windows) + package * + library-for-ghci: True + +import: cabal.project.rts + package libffi-clib - ghc-options: -no-rts -optc-Wno-error + ghc-options: -no-rts -- We end up injecting the following depednency: -- @@ -196,12 +200,15 @@ package ghc-internal flags: +bignum-native ghc-options: -no-rts -package rts - ghc-options: -no-rts - flags: +tables-next-to-code +package text + flags: -simdutf -package rts-headers - ghc-options: -no-rts +-- TODO: What is this?

If we have: assignment: = node: = then clearly the two conflict, because we cannot move one statement past the other, as they assign two different values to the same local register. (Recall that 'conflicts (local_reg,expr) node' is False if and only if the assignment 'local_reg = expr' can be safely commuted past the statement 'node'.) The fix is to update 'GHC.Cmm.Sink.localRegistersConflict' to take into account the following two situations: (1) 'node' defines the LHS local register of the assignment, (2) 'node' defines a local register used in the RHS of the assignment. The bug is precisely that we were previously missing condition (1).

Spill the data currently in the register. That is, do a spill with a format that matches what's currently in the register. 2. Update the register assignment, allocating a virtual register to this real register, but crucially **updating the format** of this assignment. Due to shadowing in the Haskell code for allocRegsAndSpill_spill, we were mistakenly re-using the old format. This could lead to a situation where: a. We were using xmm6 to store a Double#. b. We want to store a DoubleX2# into xmm6, so we spill the current content of xmm6 to the stack using a scalar move (correct). c. We update the register assignment, but we fail to update the format of the assignment, so we continue to think that xmm6 stores a Double# and not a DoubleX2#. d. Later on, we need to spill xmm6 because it is getting clobbered by another instruction. We then decide to only spill the lower 64 bits of the register, because we still think that xmm6 only stores a Double# and not a DoubleX2#.

commit ensures that if we spill a register onto the stack at a given format, we then always reload the register at this same format. This ensures we don't end up in a situation where we spill F64x2 but end up only reloading the lower F64.

This is done by introducing the 'Regs' newtype around 'UniqSet RegWithFormat', for which the combining operations take the larger of the two formats instead of overriding the format. Operations on 'Regs' are defined in 'GHC.CmmToAsm.Reg.Regs'. There is a modest compile-time cost for the additional overhead for tracking register formats, which causes the metric increases of this commit. The subtle aspects of the implementation are outlined in Note [Register formats in liveness analysis] in GHC.CmmToAsm.Reg.Liveness.

with 8-bit operands, the IMUL instruction returns the result in the lower 16 bits of %rax (also known as %ax). This is different than for the other sizes, where an input at 16, 32 or 64 bits will result in 16, 32 or 64 bits of output in both %rax and %rdx. This doesn't affect the behaviour of the compiler, because we don't allow partial writes at sub-word sizes.

For example, suppose we have stack slot assigments %v1 :: FF64 |-> StackSlot 0 %v2 :: FF64 |-> StackSlot 1 Later, we start using %v1 at a larger format (e.g. F64x2) and we need to spill it again. Then we **must not** use StackSlot 0, as a spill at format F64x2 would clobber the data in StackSlot 1. This can cause some fragmentation of the `StackMap`, but that's probably OK.

This call has been missing since 2009! commit c43c981705ec33da92a9ce91eb90f2ecf00be9fe Author: Simon Peyton Jones Date: Fri Oct 23 16:15:51 2009 +0000 Fixed by re-combining `dumpBindUDs` and `dumpUDs`. * I think there was another bug involving the quantified type variables in polymorphic specialisation. In any case I refactored `specHeader` and `spec_call` so that the former looks for the extra quantified type variables rather than the latter. This is quite a worthwhile simplification: less code, easier to grok.

This is not the case, e.g. in some situations involving exact names (see the test-case). The fix is to first check whether the node is present in the graph at all, instead of panicking, just to report that there is no path.

This accommodates the fact that pattern synonym declarations without a type signature can contain unfilled metavariables, e.g. if the RHS of the pattern synonym involves view-patterns whose type mentions promoted (level 0) metavariables. Just like we do for ordinary function bindings, we should allow these metavariables to be settled later, instead of eagerly performing a final zonk-to-type. Now, the final zonking-to-type for pattern synonyms is performed in GHC.Tc.Module.zonkTcGblEnv.

For example, if a rule is always active, we only fire rules that are themselves always active when simplifying the RHS. Ditto for inline activations. This is achieved by setting the simplifier phase to a range of phases, using the new SimplPhaseRange constructor. Then: 1. When simplifying the RHS of a rule, or of a stable unfolding, we set the simplifier phase to a range of phases, computed from the activation of the RULE/unfolding activation, using the function 'phaseFromActivation'. The details are explained in Note [What is active in the RHS of a RULE?] in GHC.Core.Opt.Simplify.Utils. 2. The activation check for other rules and inlinings is then: does the activation of the other rule/inlining cover the whole phase range set in sm_phase? This continues to use the 'isActive' function, which now accounts for phase ranges. On the way, this commit also moves the exact-print SourceText annotation from the Activation datatype to the ActivationAnn type. This keeps the main Activation datatype free of any extra cruft.

Add -dsuppress-uniques to T26349 to fix cross-platform stderr mismatch (unique suffixes differ between Linux and Windows). --- testsuite/tests/codeGen/should_run/all.T | 2 +- .../tests/simplCore/should_compile/T26349.hs | 11 + .../simplCore/should_compile/T26349.stderr | 10 + .../tests/simplCore/should_compile/T26615.hs | 6 + .../simplCore/should_compile/T26615.stderr | 2574 +++++++++++++++++ .../tests/simplCore/should_compile/T26615a.hs | 189 ++ .../tests/simplCore/should_compile/T26709.hs | 11 + .../simplCore/should_compile/T26709.stderr | 34 + .../tests/simplCore/should_compile/T26722.hs | 9 + .../simplCore/should_compile/T26722.stderr | 1 + .../tests/simplCore/should_compile/T26805.hs | 29 + .../simplCore/should_compile/T26805.stderr | 1 + .../tests/simplCore/should_compile/T26826.hs | 86 + .../simplCore/should_compile/T8331.stderr | 145 +- .../tests/simplCore/should_compile/all.T | 2 +- testsuite/tests/th/T26568.stderr | 6 +- 16 files changed, 2967 insertions(+), 149 deletions(-) create mode 100644 testsuite/tests/simplCore/should_compile/T26349.hs create mode 100644 testsuite/tests/simplCore/should_compile/T26349.stderr create mode 100644 testsuite/tests/simplCore/should_compile/T26615.hs create mode 100644 testsuite/tests/simplCore/should_compile/T26615.stderr create mode 100644 testsuite/tests/simplCore/should_compile/T26615a.hs create mode 100644 testsuite/tests/simplCore/should_compile/T26709.hs create mode 100644 testsuite/tests/simplCore/should_compile/T26709.stderr create mode 100644 testsuite/tests/simplCore/should_compile/T26722.hs create mode 100644 testsuite/tests/simplCore/should_compile/T26722.stderr create mode 100644 testsuite/tests/simplCore/should_compile/T26805.hs create mode 100644 testsuite/tests/simplCore/should_compile/T26805.stderr create mode 100644 testsuite/tests/simplCore/should_compile/T26826.hs diff --git a/testsuite/tests/codeGen/should_run/all.T b/testsuite/tests/codeGen/should_run/all.T index ea0a3ef1ecc4..fb861a8bf0a2 100644 --- a/testsuite/tests/codeGen/should_run/all.T +++ b/testsuite/tests/codeGen/should_run/all.T @@ -257,4 +257,4 @@ test('CCallConv', [req_c], compile_and_run, ['CCallConv_c.c']) test('T25364', normal, compile_and_run, ['']) test('T26061', normal, compile_and_run, ['']) test('T24016', normal, compile_and_run, ['-O1 -fPIC']) -test('T26537', js_broken(26558), compile_and_run, ['-O2 -fregs-graph']) +test('T26537', [js_broken(26558), compile_timeout_multiplier(5)], compile_and_run, ['-O2 -fregs-graph']) diff --git a/testsuite/tests/simplCore/should_compile/T26349.hs b/testsuite/tests/simplCore/should_compile/T26349.hs new file mode 100644 index 000000000000..cf916c515240 --- /dev/null +++ b/testsuite/tests/simplCore/should_compile/T26349.hs @@ -0,0 +1,11 @@ +{-# LANGUAGE DeepSubsumption, RankNTypes #-} +module T26349 where + +{-# SPECIALIZE INLINE mapTCMT :: (forall b.

The register allocator must know this to avoid clobbering live values. Update regUsageOfInstr to list the destination in both src and dst sets.

This should be SXTW (sign-extend word, 32-bit). SXTH only sign-extends the lower 16 bits, producing wrong results for 32-bit values whose bit 15 differs from bit 31. Uncomment the SXTW constructor in the Instr type and wire it through regUsageOfInstr, patchRegsOfInstr, Ppr, and instructionName. Includes assembly output test (grep for sxtw) and runtime test verifying sign extension of negative Int32 values to Int64.

This should be LSR (logical/unsigned shift right). After zero-extension the upper bits happen to be 0 so ASR produces the same result, but it is semantically wrong and would break if the zero-extension were ever optimized away. Includes assembly output test (grep for lsr) and runtime test verifying unsigned right shift of Word8 and Word16 values.

By default, this flag is disabled, as it potentially increases memory-usage. This interacts with the flag `-fno-load-initial-targets` as follows: * If no module is loaded, no module is added as an interactive import. * If a reload loads up to a module, all loaded modules are added as interactive imports. * Unloading modules removes them from the interactive context. Fixes #26866 by rendering the use of a `-ghci-script` to achieve the same thing redundant. --- compiler/GHC/Driver/Flags.hs | 2 + compiler/GHC/Driver/Session.hs | 1 + docs/users_guide/ghci.rst | 13

Previously a `--enable-dynamic` autoconf toggle, together with the `m4/accumulate.m4` helper macros, generated cabal.project.stage2.settings from a .in template, while the Makefile separately appended --enable-dynamic to GHC_CONFIGURE_ARGS when DYNAMIC=1. Keeping these two mechanisms in sync was fragile. Now the stage2 configuration is split into a shared cabal.project.stage2.common plus two thin variants that import it: - cabal.project.stage2.static (default; shared: False) - cabal.project.stage2.dynamic (shared: True, executable-dynamic: True, rts +dynamic) The Makefile selects the project file directly through DYNAMIC_SUFFIX and the new CABAL_PROJECT_FILE variable, so DYNAMIC=1 picks the dynamic file without any configure round-trip.
