...} I used llvm-2.6 compiled from source and the latest llvm-gcc binaries for Linux x86_64. This code worked just fine with older versions of llvm-gcc on 32 bit Linux. FD_ZERO is defined in /usr/include/bits/select.h like this: # if __WORDSIZE == 64 # define __FD_ZERO_STOS "stosq" # define __FD_SET_BTS "btsq" # define __FD_CLR_BTR "btrq" # define __FD_ISSET_BT "btq" # else # define __FD_ZERO_STOS "stosl" # define __FD_SET_BTS "btsl" # define __FD_CLR_BTR "btrl" # define __FD_ISSET_BT "b...

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*

...lvm option), I got the following inline assembly in my > llvm byte code: this comes directly from your system headers (/usr/include/bits/select.h) and as such doesn't really have anything to do with llvm-gcc: #if defined __GNUC__ && __GNUC__ >= 2 # if __WORDSIZE == 64 # define __FD_ZERO_STOS "stosq" # else # define __FD_ZERO_STOS "stosl" # endif # define __FD_ZERO(fdsp) \ do { \ int __d0, __d1; \ __asm__ __volatile__ ("...
