[PATCH][ARM] Tests for arm_restrict_it patterns in thumb2.md
Fri Feb 5 10:00:00 GMT 2016
I've been auditing the patterns in the arm backend that were added/modified for -mrestrict-it
and I've come up with a few runtime tests that end up generating those patterns.
This patch contains 4 tests for 4 patterns that have paths specific to -mrestrict-it.
There were some patterns like thumb2_mov_negscc_strict_it and thumb2_mov_notscc_strict_it
that I could not generate at all, because the earlier RTL optimisers always generated some
equivalent but different (and at least as good) so these splitters never matched.
I think we could safely remove them, but not at this stage.
These tests should give us a bit more test coverage into the -mrestrict-it functionality.
Ok for trunk?
