[Transforms] Convert some tests to opaque pointers (NFC)

2023-01-05T11:43:45+00:00

These are all tests where conversion worked automatically, and
required no manual fixup.

[llvm] Update tests that got missed in adee485adf84ae8a.

[SCEV] Pass NoWrapFlags when expanding an AddExpr

2019-06-14T09:19:41+00:00

InsertBinop now accepts NoWrapFlags, so pass them through when
expanding a simple add expression.

This is the first re-commit of the functional changes from rL362687,
which was previously reverted.

Revert "[SCEV] Use wrap flags in InsertBinop"

2019-06-06T12:35:46+00:00

This reverts commit r362687. Miscompiles llvm-profdata during selfhost.

[SCEV] Use wrap flags in InsertBinop

2019-06-06T08:56:26+00:00

If the given SCEVExpr has no (un)signed flags attached to it, transfer
these to the resulting instruction or use them to find an existing
instruction.

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.

llvm-svn: 358552

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.

[LSR] Don't force bases of foldable formulae to the final type.

2018-02-01T06:38:34+00:00

Summary:
Before emitting code for scaled registers, we prevent
SCEVExpander from hoisting any scaled addressing mode
by emitting all the bases first. However, these bases
are being forced to the final type, resulting in some
odd code.

For example, if the type of the base is an integer and
the final type is a pointer, we will emit an inttoptr
for the base, a ptrtoint for the scale, and then a
'reverse' GEP where the GEP pointer is actually the base
integer and the index is the pointer. It's more intuitive
to use the pointer as a pointer and the integer as index.

[x86] auto-generate complete checks; NFC

2018-01-26T22:06:07+00:00

llvm-svn: 323571

Reapply fix PR23384 (part 3 of 3) r304824 (was reverted in r305720).

2017-08-07T19:56:34+00:00

The root cause of reverting was fixed - PR33514.

Summary:
The patch makes instruction count the highest priority for
 LSR solution for X86 (previously registers had highest priority).
