It looks like there's yet more fallout from your PR target/19653
patch. This time I'm seeing three new testsuite failures on
FAIL: gcc.c-torture/execute/20050121-1.c execution, -O0
FAIL: gcc.c-torture/execute/complex-6.c execution, -O0
FAIL: gcc.target/x86_64/abi/test_complex_returning.c execution, -O0
Andrew Pinksi has managed to narrow down the regression to between
I investigated the problem with complex-6.c and the point of divergence
is in .136r.lreg where we choose different register preferences
from before your change. I also tried the "force_reg" fix that
David Edelsohn and I looked into for the AIX fallout, but this
failure seems unrelated to his incorrect SUBREG issue.
I was wondering if you could a look? It may be another latent bug
that's been exposed by your and Dale's changes.
