Aditya Nandakumar	3ba0d94bce	[GISel]: Change how CSE is enabled by default for each pass https://reviews.llvm.org/D57178 Now add a hook in TargetPassConfig to query if CSE needs to be enabled. By default this hook returns false only for O0 opt level but this can be overridden by the target. As a consequence of the default of enabled for non O0, a few tests needed to be updated to not use CSE (by passing in -O0) to the run line. reviewed by: arsenm llvm-svn: 352126	2019-01-24 23:11:25 +00:00

[GISel]: Change how CSE is enabled by default for each pass

https://reviews.llvm.org/D57178

Now add a hook in TargetPassConfig to query if CSE needs to be
enabled. By default this hook returns false only for O0 opt level but
this can be overridden by the target.
As a consequence of the default of enabled for non O0, a few tests
needed to be updated to not use CSE (by passing in -O0) to the run
line.
