Not just one of them Summary: The multiversioning code repurposed the code from __builtin_cpu_supports for checking if a single feature is enabled. That code essentially performed (_cpu_features & (1 << C)) != 0. But with the multiversioning path, the mask is no longer guaranteed to be a power of 2. So we return true anytime any one of the bits in the mask is set not just all of the bits. The correct check is (_cpu_features & mask) == mask Reviewers: erichkeane, echristo Reviewed By: echristo Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D53460 ------------------------------------------------------------------------ llvm-svn: 344923
*	[X86] Add support for __builtin_cpu_init	Craig Topper	2017-08-28	1	-0/+4
\| \| \| \| \| \| \| \| \| \|	This adds builtin_cpu_init which will emit a call to cpu_indicator_init in libgcc or compiler-rt. This is needed to support builtin_cpu_supports/builtin_cpu_is in an ifunc resolver. Differential Revision: https://reviews.llvm.org/D36336 llvm-svn: 311874
*	Fix CHECK directives that weren't checking.	Hans Wennborg	2015-08-31	1	-1/+1

*	Add support for the x86 builtin __builtin_cpu_supports.	Eric Christopher	2015-06-29	1	-0/+16
	This matches the implementation of the gcc support for the same feature, including checking the values set up by libgcc at runtime. The structure looks like this: unsigned int __cpu_vendor; unsigned int __cpu_type; unsigned int __cpu_subtype; unsigned int __cpu_features[1]; with a set of enums to match various fields that are field out after parsing the output of the cpuid instruction. This also adds a set of errors checking for valid input (and cpu). compiler-rt support for this and the other builtins in this family (__builtin_cpu_init and __builtin_cpu_is) are forthcoming. llvm-svn: 240994
