Hi Jeff,
Thanks for the suggestion. I did a bootstrap x86_64 build before and after my
patch and looked for differences in the last stage object files and there were
plenty of them. I chose a nice simple function (check_callers) from
ipa-inline-analysis.c and reduced it to a small test case. Hope this is ok.
Testing done:
* aarch64 built, "make check" no regressions
* aarch64_be built, "make check" no regressions
* x86_64 built, "make check" no regressions
ChangeLog:
2015-05-15 David Sherwood <david.sherw...@arm.com>
* loop-invariant.c (create_new_invariant): Don't calculate address cost
if mode is not a scalar integer.
(get_inv_cost): Increase computational cost for unused invariants.
* testsuite/gcc.dg/loop-invariant.c: New testcase.
Thanks. Installed on the trunk after fixing a couple trivial whitespace
nits.
Jeff
