Revert "[NFCI] Regenerate SROA/LoopVectorize test checks"

2022-04-03T23:15:30+00:00

This reverts commit 14e3450fb57305aa9ff3e9e60687b458e43835c9.

[NFCI] Regenerate LoopVectorize test checks

2022-04-03T19:56:24+00:00

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.

[DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label.

2018-05-09T02:40:45+00:00

In order to set breakpoints on labels and list source code around
labels, we need collect debug information for labels, i.e., label
name, the function label belong, line number in the file, and the
address label located. In order to keep these information in LLVM
IR and to allow backend to generate debug information correctly.
We create a new kind of metadata for labels, DILabel. The format
of DILabel is

!DILabel(scope: !1, name: "foo", file: !2, line: 3)

We hope to keep debug information as much as possible even the
code is optimized. So, we create a new kind of intrinsic for label
metadata to avoid the metadata is eliminated with basic block.
The intrinsic will keep existing if we keep it from optimized out.
The format of the intrinsic is

llvm.dbg.label(metadata !1)

It has only one argument, that is the DILabel metadata. The
intrinsic will follow the label immediately. Backend could get the
label metadata through the intrinsic's parameter.

We also create DIBuilder API for labels to be used by Frontend.
Frontend could use createLabel() to allocate DILabel objects, and use
insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.

[LV] Move isLegalMasked* functions from Legality to CostModel

2018-02-26T11:06:36+00:00

All SIMD architectures can emulate masked load/store/gather/scatter
through element-wise condition check, scalar load/store, and
insert/extract. Therefore, bailing out of vectorization as legality
failure, when they return false, is incorrect. We should proceed to cost
model and determine profitability.

This patch is to address the vectorizer's architectural limitation
described above. As such, I tried to keep the cost model and
vectorize/don't-vectorize behavior nearly unchanged. Cost model tuning
should be done separately.

Please see
http://lists.llvm.org/pipermail/llvm-dev/2018-January/120164.html for
RFC and the discussions.

Closes D43208.

Reapply "[LV] Enable vectorization of loops with conditional stores by default"

2016-12-16T19:12:02+00:00

This patch reapplies r289863. The original patch was reverted because it
exposed a bug causing the loop vectorizer to crash in the Python runtime on
PPC. The underlying issue was fixed with r289958.
