Hi,
As discussed in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68644,
the test case gcc.dg/tree-ssa/ivopts-lt-2.c does not apply to POWER
targets, as the cost model properly shows the pre-increment approach
to be preferable and results in ideal code generation. Thus, adding
powerpc*-*-* to the list of targets to skip for this test.
Verified on powerpc64le-unknown-linux-gnu. Is this ok for trunk?
ENOPATCH, but it's obvious what the patch should be, so OK.
