dlang runtime编译

[lotusdeng]

缘由

• 查找dlang像golang gctrace那样的功能，打印每次GC的时间、对象数，网上找遍了也没找到，没办法想着在drutime代码里添加

下载dmc

• http://ftp.digitalmars.com/dmc.zip
• 将C:\dmc\bin目录添加到PATH

方法

• 例如修改C:\D\dmd2\src\druntime\src\gc\impl\conservative\gc.d fullcollect函数里最后添加打印

    size_t fullcollect(bool nostack = false) nothrow
    {
        .....
        if(config.profile)
        {
            printf("Gcx.fullcollect, use:%d, freePages:%d\n", (stop-start), (freedLargePages + 
            freedSmallPages));
        }
        return freedLargePages + freedSmallPages;
    }

• 执行C:\D\dmd2\build.bat

cd C:\D\dmd2\src\druntime
make -f win32.mak

cd C:\D\dmd2\src\phobos
make -f win32.mak

copy /Y phobos.lib C:\D\dmd2\windows\lib
