[PATCH] D97106: [UpdateTestChecks] Warn if any function conflicts under the same prefix

[Roman Lebedev via Phabricator via llvm-commits]

lebedev.ri added a comment.

This should only warn if said occurrence would lead to the loss of the checks for the function.
I.e. it should not warn on prefix `ALL` given

  ; RUN: opt < %s -instcombine -S | FileCheck --check-prefixes=ALL,IC %s
  ; RUN: opt < %s -vectorize-slp -S | FileCheck --check-prefixes=ALL,SLP %s
