[PATCH] D103550: [SampleFDO] New hierarchical discriminator for FS SampleFDO (llvm-profdata part)

[Wenlei He via Phabricator via llvm-commits]

wenlei added inline comments.


================
Comment at: llvm/include/llvm/Support/Discriminator.h:59
   Base = 0,
   Pass0 = 0,
   Pass1 = 1,
----------------
The cl::opt FSDiscriminatorPassOption doesn't have Pass0. Was it intentional to allow Pass0 as alias for Base?
