[PATCH] D17108: [PGO] Add another interface for annotateValueSite

[Rong Xu via llvm-commits]

xur added a comment.

my indirect-call promotion implementation supports multiple targets (specified the by an option)  for a single callsite and the transformation pass can be called multiple times. The promotion stops at the first non-promoted direct target (as it's sorted on the count).

For example, for a callsite with the the following valuedata {<func1, 100> <func2, 80> <func3,10>}, after we promote func1 and cannot promote func2, I will attach {<func2, 80> <func3, 10>} to the indirect-call instruction.
