Kostya Serebryany 3386d25257 [asan] Optimize accesses to global arrays with constant index ... Summary: Given a global array G[N], which is declared in this CU and has static initializer avoid instrumenting accesses like G[i], where 'i' is a constant and 0<=i<N. Also add a bit of stats. This eliminates ~1% of instrumentations on SPEC2006 and also partially helps when asan is being run together with coverage.

Hello
InstCombine	Remove x86_sse42_crc32_64_8 intrinsic. It has no functional difference from x86_sse42_crc32_32_8 and was not mapped to a clang builtin. I'm not even sure why this form of the instruction is even called out explicitly in the docs. Also add AutoUpgrade support to convert it into the other intrinsic with appropriate trunc and zext.	2013-10-15 05:20:47 +00:00
