Remove explicit uses of -emit-llvm, the test infrastructure adds it automatically. Use -S with llvm-gcc rather than -c, so tests can work when llvm-gcc is really dragonegg (which can output IR with -S but not -c). llvm-svn: 120158 2010-11-25 21:24:35 +00:00			`// RUN: %llvmgcc %s -S -o - \| FileCheck %s`
This test passes now on ppc darwin; if it doesn't pass on some other ppc say something on the list. llvm-svn: 95265 2010-02-03 22:33:17 +00:00			`// XFAIL: sparc`
