Subject: Enhance 'diagtool list-warnings' to report number of diagnostics covered directly... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a437b84765d6b98d57f2789435ad641f1dd61474;p=clang

Enhance 'diagtool list-warnings' to report number of diagnostics covered directly under -Wpedantic, and enhance warning-flags.c test to test that this set does not grow.

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159893 91177308-0d34-0410-b5e6-96231b3b80d8
