Subject: [PATCH 1/4] [SPIR-V] Fix structurizer issues
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The "topological" sorting was behaving incorrectly in some cases:
the exit of a loop could have a lower rank than a node in the loop.
This causes issues when structurizing some patterns, and also codegen
issues as we could generate BBs in the incorrect order in regard to the
SPIR-V spec.
Fixing this ordering alone broke other parts of the structurizer, which
by luck worked. Had to fix those.
Added more test cases, especially to test basic patterns.
I also needed to tweak/disable some tests for 2 reasons:
- SPIR-V now required reg2mem/mem2reg to run. Meaning dead stores
are optimized away. Some tests require tweaks to avoid having the
whole function removed.
- Mem2Reg will generate variable & load/stores. This generates
G_BITCAST in several cases. And there is currently something wrong
we do with G_BITCAST which causes MIR verifier to complain.
Until this is resolved, I disabled -verify-machineinstrs flag on
those tests.
