[LLVMdev] Help with gcc SSE intrinsics
...is for hours and can't figure it out. I know I'm
missing something obvious.
I've been spending the past few days beefing up the vector support in the C
Backend. This should help us debug vector code that's miscompiled. But
gcc doesn't like this fragment:
((double *)(&llvm_cbe_r1147))[0u] =
(((llvm_cbe_r1146__BITCAST_TEMPORARY.Int64 = 4ull,
llvm_cbe_r1146__BITCAST_TEMPORARY .Double)));
llvm_cbe_r1148 = __builtin_ia32_movddup(llvm_cbe_r1147);

__vector__'
from type 'int'

I don't see __builtin_ia32_movddup defined anywhere in the llvm-gcc
sources. That's probably it.
