Roman Lebedev	aa2009fe78	[NFCI][SimplifyCFG] Mark all the SimplifyCFG tests that already don't invalidate DomTree as such ... First step after e113317958, in these tests, DomTree is valid afterwards, so mark them as such, so that they don't regress. In further steps, SimplifyCFG transforms shall taught to preserve DomTree, in as small steps as possible.	2020-12-17 01:03:49 +03:00
Chen Zheng	e8425b27fe	[PowerPC] add store (load float*) pattern to isProfitableToHoist ... store (load float*) can be optimized to store(load i32*) in InstCombine pass. Add store (load float*) to isProfitableToHoist to make sure we don't break the opt in InstCombine pass.

Roman Lebedev	04b729d076	[NFCI][SimplifyCFG] Guard common code hoisting with a (default-on) flag ... Common code sinking is already guarded with a (with default-off!) flag, so add a flag for hoisting, too. D84108 will hopefully make hoisting off-by-default too.	2020-07-20 10:29:57 +03:00
