[GlobalISel] Put legalizer rule debug behind a verbose option. (#138277)

2025-05-17T15:48:44+00:00

With the large number of G_ opcodes now present, this debug information
emitted for checking the global isel legalizer rules are valid is quite
verbose and runs even when gisel is not being used. This makes it
especially verbose when running a single pass with -debug.

This patch puts it behind a verbose debug option so that most people
don't need to worry about it.

[GISEL][NFC] Use getElementCount instead of getNumElements in more places

2024-03-27T00:41:46+00:00

These cases in particular are  done as a precommit to support
legalization, regbank selection, and instruction selection for extends,
splat vectors, and integer compares in #85938.

[llvm] Move CodeGenTypes library to its own directory (#79444)

Finally addresses https://reviews.llvm.org/D148769#4311232 :)

No behavior change.

[GlobalISel] Add support for *_fpmode intrinsics

2023-10-09T14:14:07+00:00

The change implements support of the intrinsics `get_fpmode`,
`set_fpmode` and `reset_fpmode` in Global Instruction Selector. Now they
are lowered into library function calls.

Restore CodeGen/LowLevelType from `Support`

2023-05-02T15:13:19+00:00

This is rework of;
  - D30046 (LLT)

Since I have introduced `llvm-min-tblgen` as D146352, `llvm-tblgen`
may depend on `CodeGen`.

`LowLevlType.h` originally belonged to `CodeGen`. Almost all userse are
still under `CodeGen` or `Target`. I think `CodeGen` is the right place
to put `LowLevelType.h`.

`MachineValueType.h` may be moved as well. (later, D149024)

I have made many modules depend on `CodeGen`. It is consistent but
inefficient. It will be split out later, D148769

Besides, I had to isolate MVT and LLT in modmap, since
`llvm::PredicateInfo` clashes between `TableGen/CodeGenSchedule.h`
and `Transforms/Utils/PredicateInfo.h`.
(I think better to introduce namespace llvm::TableGen)

Depends on D145937, D146352, and D148768.

[MC] Make more use of MCInstrDesc::operands. NFC.

2023-01-23T11:31:41+00:00

Change MCInstrDesc::operands to return an ArrayRef so we can easily use
it everywhere instead of the (IMHO ugly) opInfo_begin and opInfo_end.
A future patch will remove opInfo_begin and opInfo_end.

Also use it instead of raw access to the OpInfo pointer. A future patch
will remove this pointer.
