Given all of the above testing I'm reasonably confident that this works.
However this is such a large change [1] that there's a non-zero chance
of at least one glitch - let me know if you see any breakages.
The mips*-*-* targets are not building. It looks like the mips reorg
pass (pass_mips_machine_reorg2) in config/mips/mips.c was not converted
and/or was not converted correctly.
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 (buildhost=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.
