Sorry about this.

I was able to reproduce this build error with configure
--target=mips-linux-elf:
../../src/gcc/config/mips/mips.c:16379:28: error: expected
primary-expression before ‘.’ token

I'm attaching a patch which fixes that issue for me.  Only lightly
tested (build&host=x86_64, target as above) - I'm able to build stage1,
and cc1 appears to generate assembler on a simple test case.  I stepped
through the changed code in the debugger and it appears to do the right
thing.  However I'm not familiar with the internals of the pass in
question.

OK.  Thanks for the quick fix!
