Subject: Driver: Lookup program names using llvm::sys::Program::FindProgramByName
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=632f50edc08c76ebc643a0d4871bae33a55d7b4e;p=clang

Driver: Lookup program names using llvm::sys::Program::FindProgramByName
if our usual methods fail. This isn't necessary for running the tool,
but improves the accuracy of logging output.

Also, have GCC tools lookup gcc program path.
