This revision is now accepted and ready to land.
================
Comment at: llvm/lib/CodeGen/TargetPassConfig.cpp:1116-1118
+ if (EnableFSDiscriminator)
+ addPass(createMIRAddFSDiscriminatorsPass(
+ sampleprof::FSDiscriminatorPass::Pass1));
----------------
How about adding a comment that the pass is intentionally placed before regalloc, in case some other passes are inserted in between in the future.
