[PATCH] D13363: [DeadStoreElimination] Add support for non-local DSE

[Ivan Baev via llvm-commits]

ivanbaev updated this revision to Diff 40106.
ivanbaev added a comment.

Added option -enable-nonlocal-dse to enable/disable the feature.

All QuIC internal correctness and performance tests are good. 
On Arm/AArch64 processor at -O2, the patch improves run-time performance of:
eembc/networking_suite/qos by 8%,
eembc/comsumer_suite/cjpegv2data7 by 16%,
spec2006/sjeng by 1.5%

Please, take another look at the patch. I think all suggestions and comments have been addressed.
I appreciate if you could run the patch on your applications on additional targets and measure the impact.

Best regards,
Ivan
