I think this patch is causing an ICE while building glibc on MIPS.  I am
building a toolchain for mips-mti-linux-gnu and when compiling
sysdeps/gnu/siglist.c from glibc for mips64r2 (N32 ABI) I get the
following ICE.

I will try to create a preprocessed source file for this but I wanted
to report it first to see if anyone else is seeing it on other
