Fix the assembler to print a better relocatable expression error diagnostic that includes location information. Currently if one has this assembly: .quad (0x1234 + (4 * SOME_VALUE)) where SOME_VALUE is undefined ones gets the less than useful error message with no location information: % clang -c x.s clang -cc1as: fatal error: error in backend: expected relocatable expression With this fix one now gets a more useful error message with location information: % clang -c x.s x.s:5:8: error: expected relocatable expression .quad (0x1234 + (4 * SOME_VALUE)) ^ To do this I plumbed the SMLoc through the MCObjectStreamer EmitValue() and EmitValueImpl() interfaces so it could be used when creating the MCFixup. rdar://12391022 llvm-svn: 206906
