The -save-temps option now behaves like described in GCC 4.5 release notes (you can specify output directory for temporary files with -save-temps=obj -o $DIRNAME). I do not have GCC 4.5 installed, so if there are any inconsistencies between llvmc and GCC in the implementation of this feature, please let me know. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74190 91177308-0d34-0410-b5e6-96231b3b80d8
