Hi,
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79160 records that
gcc.target/powerpc/vsx-elemrev-4.c fails on powerpc64 big-endian. The
test was developed just prior to the introduction of D-form memory
access instructions lxv and stxv, so it relied on output of X-form
instructions lxvx and stxvx. Either would be acceptable, but with the
introduction of the D-form instructions, they are preferred by the code
generator when they apply. I've changed the test case to accept either
the D-form or the X-form instructions.
Tested adn veriried on powerpc64-unknown-linux-gnu. Ok for trunk?
Thanks,
Bill
