hi, When I compile Gcc with MSYS2 on Windows.I have encountered a thorny
issue.
In order to output the Intel assembly file by default, I modified the
gcc/config/i386/i386.opt file as follows
masm=
Target RejectNegative Joined Enum(asm_dialect) Var(ix86_asm_dialect)
Init(ASM_INTEL)
Use given assembler dialect.
however, An error occurred when compiling to
libgcc/config/i386/sfp-exceptions.c
file， it tell me :
C:\MSYS\MSYS32\tmp\cctIKXUx.s: Assembler messages:
C:\MSYS\MSYS32\tmp\cctIKXUx.s:69: Error: no such instruction: `fdivs DWORD
PTR [esp]'
C:\MSYS\MSYS32\tmp\cctIKXUx.s:135: Error: no such instruction: `fdivs DWORD
PTR [esp]'
I checked Intel's developer's manual，I can't find a description of this
directive. So I want to know what's going on.
