            Bug ID: 20385
           Summary: LLVM (through clang) doesn't distinguish between -fpic
                    and -fPIC
           Product: libraries
           Version: trunk
          Hardware: Macintosh
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: Common Code Generator Code
          Assignee: unassignedbugs at nondot.org

    Classification: Unclassified

Clang has preliminary support for -fpic vs -fPIC, but the flag is not
propagated to the LLVM libraries in any way.  A quick code check shows it
enabling flag '-pic-level' setting it to 1 or 2 (1 for -fpic, 2 for -fPIC).

The distinction between -fpic and -fPIC is relevant to RISC architectures
primarily, in my use case it's PowerPC (32-bit).
