             Bug #: 11924
           Summary: clang makefile assumes all powerpc systems have
                    altivec
           Product: clang
           Version: unspecified
          Platform: Macintosh
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Frontend
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: wala1 at illinois.edu
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Compiling clang 3.0 with g++ 4.4.5 on a PowerPC G3 system (no AltiVec) running
Linux results in a clang binary which crashes when the lexer runs. The problem
is these lines in lib/Lex/Makefile which cause the compiler to compile a
section with AltiVec instructions in Lexer.cpp:

ifeq ($(ARCH),PowerPC)
CXX.Flags += -maltivec
endif

These lines are still in trunk. When I remove them then the compiled binary
runs fine. Not all PowerPC systems have AltiVec support, so these lines should
be removed or replaced with a more intelligent test.
