MaskRay added inline comments.

Comment at: clang/lib/Driver/ToolChains/Gnu.cpp:1964
for (StringRef Candidate : CandidateBiarchTripleAliases)
ScanLibDirForGCCTriple(TargetTriple, Args, LibDir, Candidate,
/*NeedsBiarchSuffix=*/ true);
----------------
Its use of GCCDirExists is uninitialized. I suggest that you set GCCDirExists
and GCCCrossDirExists to be conservative.

Comment at: clang/lib/Driver/ToolChains/Gnu.cpp:2469
} Suffixes[] = {
- // This is the normal place.
- {"gcc/" + CandidateTriple.str(), "../..", true},
+ // This is the normal place if Clang is installed alongside with GCC,
+ // probably with the same prefix. But it's likely does not exists in
----------------
> Clang is installed alongside with GCC
This is not correct. (1) clang does not need to be installed (it can be used in
the build directory) (2) You can set --prefix (-B) and --sysroot to affect
detected prefixes. Clang does not need to be beside GCC.
