Nick Lewycky 51a009092c Make _mm_cmpgt_epi8 immute to -funsigned-char.

Bob Wilson c9b97cc1da Fix vector macros to correctly check argument types. <rdar://problem/10261670>

Eli Friedman 89c11337ba Add _mm_comige_sd to emmintrin.h, since I apparently forgot to do this in r138769.

Eli Friedman 9bb51adcce Tweak *mmintrin.h so that they don't make any bad assumptions about alignment (which probably has little effect in practice, but better to get it right). Make the load in _mm_loadh_pi and _mm_loadl_pi a single LLVM IR instruction to make optimizing easier for CodeGen.

Eli Friedman f8cb480528 Add missing function _mm_ucomige_sd to emmintrin.h. PR10803.

Bill Wendling 03e7e430c3 Add 'may_alias' attribute. Noticed by Eli. 
llvm-svn: 131278

Bill Wendling 502931fad9 Represent the unaligned loads natively. These are converted into a call to the 
correct unaligned load.

Bill Wendling e106c34817 LLVM doesn't always optimize away the four loads from this: 
(__m128){ p[0], p[1], p[2], p[3] }

which produces really bad code. This could be done in instcombine, but it's
probably better to do it in the front-end instead.

Eli Friedman 8ba29d8e7f PR9866: Fix the implementation of _mm_loadl_pd and _mm_loadh_pd to not make 
bad assumptions about the alignment of the double* argument.

Chris Lattner f03406f103 don't use compound literals in MM macros, since they will be instantiated 
into user code which may warn about them with -pedantic.  Patch by Jonathan Sauer!

Bill Wendling b9c9e34cb3 Just use a native "load" instead of translating the builtin later. Clang can 
take it!

I wasn't able to get __builtin_ia32_loaddqu to transform into an unaligned
load...I'll have to look into it further.

Chris Lattner 1750cb037d __builtin_ia32_psrldqi128 too 
llvm-svn: 115301
 2010-10-01 06:58:49 +00:00
Chris Lattner 81f347fe6d the second argument to __builtin_ia32_pslldqi128 must be an immediate, 
so it needs to be called from a macro, not a function.  This is a necessary
but insufficient step towards fixing PR8221

Eric Christopher 2a9898f0a2 Move some type defines from smmintrin.h to emmintrin.h to match where 
gcc defines them.

 2010-08-20 16:47:17 +00:00
Chris Lattner 9052c35479 fix some vector extractions to return properly zero extended values 
(instead of sign extending) to match ICC.  GCC is changing this in 
a series of their own PRs (e.g. 41323).

Eli Friedman 07c89c6b3e PR7588: Fix the _mm_shufflehi_epi16 macro. (The issue was an oversight 
involving operator precedence.)

llvm-svn: 107902
 2010-07-08 20:09:45 +00:00
Chris Lattner 8b3b145342 fix _mm_shuffle_pd too, thanks to Joel Falcou for pointing this out.

 2010-05-15 16:54:46 +00:00
Chris Lattner 7eac805bb0 fix PR6658: inline isn't a keyword in C89 mode, use __inline__ instead.

Eric Christopher 33124e20c7 Migrate typedefs to the top level of xmmintrin.h and remove the same 
one from emmintrin.h.

Anders Carlsson dfa3117085 Fix PR4923.
