Re: X86 Built-in Functions

[Kimmo Fredriksson <kfredrik at cs dot joensuu dot fi>]

Ok, I partially solved this with:

#define	_mm_setzero_si128	__builtin_ia32_setzero128
#define	_mm_or_si128		__builtin_ia32_por128
#define	_mm_xor_si128		__builtin_ia32_pxor128
#define	_mm_and_si128		__builtin_ia32_pand128
#define	_mm_andnot_si128       	__builtin_ia32_pandn128
#define	_mm_srli_epi64		__builtin_ia32_psrlqi128
#define	_mm_slli_epi64		__builtin_ia32_psllqi128
#define	_mm_slli_si128		__builtin_ia32_pslldqi128
#define	_mm_srli_si128		__builtin_ia32_psrldqi128
#define	_mm_add_epi64		__builtin_ia32_paddq128
#define	_mm_sub_epi64		__builtin_ia32_psubq128

But I still haven't figured out the following:

_mm_cvtsi32_si128, _mm_cvtsi128_si32, _mm_set_epi32

Anyone?
