Subject: [ThinLTO] Use decimal suffix for promoted values to match demanglers
X-Git-Tag: llvmorg-6.0.0-rc1~6891
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0d0ba25470154bc775f6e17d852b195af0cccf67;p=platform%2Fupstream%2Fllvm.git

[ThinLTO] Use decimal suffix for promoted values to match demanglers

Summary:
Demanglers such as libiberty know how to strip suffixes of the form
\.[a-zA-Z]+\.\d+, but our current promoted value suffixes are
.llvm.${modulehash}, where the module hash is in hex. Change the
module hash to decimal to allow demanglers to handle this.
