Andrea Di Biagio dae3a5b91a [X86] Add support for Read Time Stamp Counter x86 builtin intrinsics. ... This patch: - Adds two new X86 builtin intrinsics ('int_x86_rdtsc' and 'int_x86_rdtscp') as GCCBuiltin intrinsics; - Teaches the backend how to lower the two new builtins; - Introduces a common function to lower READCYCLECOUNTER dag nodes and the two new rdtsc/rdtscp intrinsics; - Improves (and extends) the existing x86 test 'rdtsc.ll'; now test 'rdtsc.ll' correctly verifies that both READCYCLECOUNTER and the two new intrinsics work fine for both 64bit and 32bit Subtargets. llvm-svn: 207127		2014-04-24 17:18:27 +00:00
