[LLVMdev] about llvm2.7's inline assembly
Hello,
Whenever I compile a C program containing "FD_SET" function using llvm-gcc
2.7 (with -emit-llvm option), I got the following inline assembly in my
llvm byte code:
%asmtmp = call %struct.__mbstate_t asm sideeffect "cld; rep; stosl",
"={cx},={di},{ax},0,1,~{dirflag},~{fpsr},~{flags},~{memory}"(i32 0, i32
32, i32* getelementptr inbounds (%struct.__sigset_t*
