patch-r262535-clang-r202177-sparc.diff revision 269012 
1Pull in r202177 from upstream clang trunk (by Roman Divacky):
2
3  Give sparcv9 the ability to set the target cpu. Change it from accepting
4  -march which doesnt exist on sparc gcc to -mcpu. While here adjust a
5  few tests to not write an unused temporary file.
