Anna Zaks 492074fb03 [asan] Skip promotable allocas to improve performance at -O0 ... Currently, the ASan executables built with -O0 are unnecessarily slow. The main reason is that ASan instrumentation pass inserts redundant checks around promotable allocas. These allocas do not get instrumented under -O1 because they get converted to virtual registered by mem2reg. With this patch, ASan instrumentation pass will only instrument non promotable allocas, giving us a speedup of 39% on a collection of benchmarks with -O0. (There is no measurable speedup at -O1.) llvm-svn: 230724		2015-02-27 03:12:36 +00:00
