Generated tests t154 and t199 from gcc.dg/compat/struct-layout-1 fail
with an ICE compiling c_compat_y_tst.o with -m64 on powerpc64-linux.
The first started failing on 20050424, the second on 20050501, and both
have failed regularly since then, but it seems to be a latent bug
because results for regression hunts don't match up with those dates.
I'll attach minimized test cases for both. Here's the output I get from
today's mainline:
elm3b11% /opt/gcc-nightly/mline/bin/gcc -m64 -c bug_t154.c

simplify_gen_subreg of a complex MEM creates a SUBREG that cannot be recognized.
