Subject: [PGO] Use rsplit to parse value-data line in text profile file.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=3a963d121a2e690698987c175ca9760007e87935;p=llvm

[PGO] Use rsplit to parse value-data line in text profile file.
The value-data line is <PGOFuncName>:<Count_Value>. PGOFuncName might contain
':' for the internal linkage functions. We therefore need to use rsplit,
rather split, to extract the data from the line. This fixes the error when
merging a text profile file to an indexed profile file.
