This module removes the redundant stops while +preserving genuine re-entries (loop back-edges). + +It complements the MLIR passes ``CanonicalizeDebugLocationsPass`` and +``DeduplicateDebugNopsPass``: those clean up locations *before* bishengir; this +cleans up the residual scatter bishengir introduces *after* them, at the binary +level. + +Mechanism (length-preserving, relocation-safe) + bishengir encodes the line program as a single relocated + ``DW_LNE_set_address`` followed by ``DW_LNS_fixed_advance_pc`` per row, + whose operands are symbol differences patched by ``.rela.debug_line``. + Regenerating the program would reorder those relocations and corrupt the + table, so instead each dropped stop has its ``DW_LNS_copy`` opcode (0x01) + overwritten with ``DW_LNS_set_basic_block`` (0x07) -- both one-byte, zero + argument. ``set_basic_block`` emits no row, so the stop disappears and its + address folds into the previous row. No byte shifts, so ``.rela.debug_line`` + is never touched and stays valid. + +Demotion rules, applied to ``is_stmt=1`` rows in program order: + 1. Scatter -- within a sequence keep the first row per ``(file, line)``, + drop the rest. + 2. Loops -- keep every occurrence of a ``for``/``while`` header line + (detected from the source AST), so the back-edge re-stops each iteration. + 3a. Foreign -- drop rows whose file is not the user source file. + 3b. line==0 -- drop compiler-generated rows. + 3c. Over-len -- drop rows whose line exceeds the source length (safety net + for binaries built before ``CanonicalizeDebugLocationsPass`` or without + ``--enable-ms-debug``; normally a no-op). + +Rows emitted by a DWARF special opcode (e.g. the line-0 function-entry row) +cannot be edited length-preserving and are left as-is; this is harmless because +execution begins there and ``next`` never returns to it. + +Public API + rewrite_debug_line(artifact, metadata=None, options=None) + Pipeline entry.

The dunder +# builtin is reached only from the user's operator syntax. +# +# * The *entry layer* wraps ``CodeGenerator.call_Function`` and validates +# named builtins (``tl.*``), ``@jit`` composite ops (``tl.max``, +# ``tl.sum`` ...) and cann extension builtins before they run. +# +# The rules themselves live in ``op_dtype_config.py``.

The fix strips every +// non-zero-stride axis, checked or not. +// +// 2. (incidental) A zero-stride (broadcast) axis listed in boundary_check +// reached divOpFoldResult(offsetShift, 0), which emits "cannot div 0!" +// and returns an empty OpFoldResult, crashing the compiler. The fix +// skips such axes (emitting a warning) and keeps the current block size. +// +// 3. Logical axis order need not be physical major-to-minor order.
