Elad Cohen	b107a22afb	[X86] Remove the mm_malloc.h include guard hack from the X86 builtins tests ... The X86 clang/test/CodeGen/*builtins.c tests define the mm_malloc.h include guard as a hack for avoiding its inclusion (mm_malloc.h requires a hosted environment since it expects stdlib.h to be available - which is not the case in these internal clang codegen tests). This patch removes this hack and instead passes -ffreestanding to clang cc1. Differential Revision: https://reviews.llvm.org/D24825 llvm-svn: 282581	2016-09-28 11:59:09 +00:00
Michael Zuckerman	e54093fcc0	Adding front-end support to several intrinsics (bit scanning, conversion and state reading intrinsics) ... Adding LLVM front-end support to two intrinsics dealing with bit scan: _bit_scan_forward and _bit_scan_reverse. Their functionality is as described in Intel intrinsics guide: https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_bit_scan_forward&expand=371,370 https://software.intel.com/sites/landingpage/IntrinsicsGuide/#text=_bit_scan_reverse&expand=371,370 Furthermore, adding clang front-end support to these conversion intrinsics: _mm256_cvtsd_f64, _mm256_cvtsi256_si32 and _mm256_cvtss_f32. Finally, adding tests to all of the above, as well as to the state reading intrinsics _rdpmc and _rdtsc. Their functionality is also specified in the Intel intrinsics guide.
