             Bug #: 14109
           Summary: CMake build for compiler-rt should use just-built
                    clang
           Product: compiler-rt
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: compiler-rt
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: samsonov at google.com

This would be useful as:
1) We'd be able to compile compiler-rt libraries for many targets (that is, for
targets supported by clang).
2) We'd need to support a single compiler (ToT Clang) instead of all kinds of
host compilers users may have.
3) It may simplify building ASan/(MSan?) unit tests that require
instrumentation, as just-built clang would have the "-faddress-sanitizer" flag
working.
