File that shows the problem
Compiling the attached file will generate an insn not found error message if it
is compiled with the following options: -std=c99 -fno-strict-aliasing -Wall
-m32 -mpowerpc64 foo.c -S -O2.
The problem is inside of rs6000_secondary_reload, there is code for 64-bit and
32-bit. The reload insn that is returned is looking for a 64-bit scratch
register, but the combination of switches -m32 -mpowerpc64 it should be
generating a 32-bit scratch register.
