Rong Xu 4e30d875bf [SampleFDO] New hierarchical discriminator for Flow Sensitive SampleFDO ... This patch implements first part of Flow Sensitive SampleFDO (FSAFDO). It has the following changes: (1) disable current discriminator encoding scheme, (2) new hierarchical discriminator for FSAFDO. For this patch, option "-enable-fs-discriminator=true" turns on the new functionality. Option "-enable-fs-discriminator=false" (the default) keeps the current SampleFDO behavior. When the fs-discriminator is enabled, we insert a flag variable, namely, llvm_fs_discriminator, to the object. This symbol will checked by create_llvm_prof tool, and used to generate a profile with FS-AFDO discriminators enabled. If this happens, for an extbinary format profile, create_llvm_prof tool will add a flag to profile summary section. Differential Revision: https://reviews.llvm.org/D102246		2021-05-18 16:23:43 -07:00
