9815 – atomicity.h - fails to compile with -O3 -masm=intel (original) (raw)

| C:\Temp/cceyaaaa.s: Assembler messages: C:\Temp/cceyaaaa.s:59: Error: no such instruction: `xaddl ebx,DWORD PTR [eax-4]' C:\Temp/cceyaaaa.s:199: Error: no such instructio n: `addl eax,DWORD PTR [ecx]' Release: gcc-3.2.2 (mingw special 20030208-1) Environment: x86, win32 (windows 2000 pro) How-To-Repeat: a.cpp: #include int main(int argc, char *argv[]) { std::string a="a"; } Command line: gcc -O3 a.cpp -lstdc++ -masm=intel Comment 1 kfoltman 2003-02-23 09:16:01 UTC Fix: Use different versions of atomicity.h for intel and AT&T syntax. It will probably need to make the compiler issue a #define when -masm=intel is used.
