[NFC] remove explicit default value for strboolattr attribute in tests

2021-05-24T17:31:04+00:00

Since d6de1e1a71406c75a4ea4d5a2fe84289f07ea3a1, no attributes is quivalent to
setting attribute to false.

This is a preliminary commit for https://reviews.llvm.org/D99080

Migrate function attribute "no-frame-pointer-elim" to "frame-pointer"="all" as cleanups after D56351

Revert "Temporarily Revert "Add basic loop fusion pass.""

2019-04-17T04:52:47+00:00

The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Temporarily Revert "Add basic loop fusion pass."

2019-04-17T02:12:23+00:00

As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Remove irrelevant references to legacy git repositories from

2019-01-15T16:18:52+00:00

compiler identification lines in test-cases.

(Doing so only because it's then easier to search for references which
are actually important and need fixing.)

[InstCombine] Rewrite bswap/bitreverse handling completely.

2016-01-15T09:20:19+00:00

There are several requirements that ended up with this design;
  1. Matching bitreversals is too heavyweight for InstCombine and doesn't really need to be done so early.
  2. Bitreversals and byteswaps are very related in their matching logic.
  3. We want to implement support for matching more advanced bswap/bitreverse patterns like partial bswaps/bitreverses.
  4. Bswaps are best matched early in InstCombine.

The result of these is that a new utility function is created in Transforms/Utils/Local.h that can be configured to search for bswaps, bitreverses or both. InstCombine uses it to find only bswaps, CGP uses it to find only bitreversals.

We can then extend the matching logic in one place only.
