Hello, I am a Chinese developer.When compiling the gcc source code, I
encountered a rather confusing problem, but I don't know it was a bug or
not.

I compile Gcc with MSYS2 on Windows， 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 don't known why!!
