CRT library functions _adj_fdiv_m* and _adj_fdivr_m* have custom calling convention. These functions take two arguments. First argument is passed in x87 st(0) register and second argument on the stack (either 4 or 8 bytes). Function itself pops the stack (like stdcall convention) and return value is stored in x87 st(0) register.
CL.EXE compiler when invoked with flag /QIfdiv generates calls to these functions. Generated symbol names are without @SIZE suffix decoration. So for compatibility with msvc, do not decorate these symbols with @SIZE suffix (the suffix used for stdcall) in all def files. Note that neither gcc, nor clang does not provide a way to define C function declaration with this calling convention, so currently the only way how to call these functions from the assembler or via gcc inline assembly in C/C++. And therefore mingw-w64 does not provide declaration for these functions in header files. --- mingw-w64-crt/lib-common/msvcrt.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcr70.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcr71.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcr80.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcr90.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcr90d.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcrt20.def.in | 16 ++++++++-------- mingw-w64-crt/lib32/msvcrt40.def.in | 16 ++++++++-------- 8 files changed, 64 insertions(+), 64 deletions(-) diff --git a/mingw-w64-crt/lib-common/msvcrt.def.in b/mingw-w64-crt/lib-common/msvcrt.def.in index e39a0c1b8aac..b5b971d2052c 100644 --- a/mingw-w64-crt/lib-common/msvcrt.def.in +++ b/mingw-w64-crt/lib-common/msvcrt.def.in @@ -419,15 +419,15 @@ F_I386(_abnormal_termination) _access _acmdln DATA #ifdef DEF_I386 -_adj_fdiv_m16i@4 -_adj_fdiv_m32@4 -_adj_fdiv_m32i@4 -_adj_fdiv_m64@8 +_adj_fdiv_m16i ;
