Diego Novillo 9bbd13f9a0 SamplePGO - Reduce memory utilization by 10x. ... DenseMap is the wrong data structure to use for sample records and call sites. The keys are too large, causing massive core memory growth when reading profiles. Before this patch, a 21Mb input profile was causing the compiler to grow to 3Gb in memory. By switching to std::map, the compiler now grows to 300Mb in memory. There still are some opportunities for memory footprint reduction. I'll be looking at those next. llvm-svn: 255389		2015-12-11 23:21:38 +00:00
