Remove the space in the asm check so that the expression is more general and can also capture MIPS labels which can be surrounded by braces, e.g.: .4byte ($tmp1) # DW_AT_low_pc Also change optimization level to O0 because the DW_TAG_label does not appear on MIPS when -O2 is used. Patch by Milos Stojanovic. Differential Revision: https://reviews.llvm.org/D52901 llvm-svn: 343999
