[NFC][Py Reformat] Reformat lit.local.cfg python files in llvm

2023-05-17T15:03:15+00:00

This is a follow-up to b71edfaa4ec3c998aadb35255ce2f60bba2940b0
since I forgot the lit.local.cfg files in that one.

Reformatting is done with `black`.

If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours  and then reformat it
with black.

If you run into any problems, post to discourse about it and
we will try to help.

[SimplifyCFG] TryToSimplifyUncondBranchFromEmptyBlock() already knows how to preserve DomTree

2020-12-16T22:03:49+00:00

... so just ensure that we pass DomTreeUpdater it into it.

Fixes DomTree preservation for a large number of tests,
all of which are marked as such so that they do not regress.

[NFCI][SimplifyCFG] Mark all the SimplifyCFG tests that already don't invalidate DomTree as such

2020-12-16T22:03:49+00:00

First step after e1133179587dd895962a2fe4d6eb0cb1e63b5ee2,
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.

[PowerPC] add store (load float*) pattern to isProfitableToHoist

2020-07-22T00:55:13+00:00

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.

[NFCI][SimplifyCFG] Guard common code hoisting with a (default-on) flag

2020-07-20T07:29:57+00:00

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.

[PowerPC] implement target hook isProfitableToHoist

2020-03-19T04:17:25+00:00

On Powerpc fma is faster than fadd + fmul for some types,
(PPCTargetLowering::isFMAFasterThanFMulAndFAdd). we should implement target
hook isProfitableToHoist to prevent simplifyCFGpass from breaking fma
pattern by hoisting fmul to predecessor block.
