[TableGen] Use range-based for loops (NFC) (#144283)

2025-06-16T04:00:29+00:00

[GISel][AArch64] Allow PatLeafs to be imported in GISel which were previously causing warnings (#140935)

2025-06-09T08:02:56+00:00

Previously PatLeafs could not be imported, causing the following
warnings to be emitted when running tblgen with
`-warn-on-skipped-patterns:`
```
/work/clean/llvm/lib/Target/AArch64/AArch64InstrInfo.td:2631:1: warning: Skipped pattern: Src pattern child has unsupported predicate
def : Pat<(i64 (mul top32Zero:$Rn, top32Zero:$Rm)),
^
```
These changes allow the patterns to now be imported successfully.

[LLVM][TableGen] Use StringRef for various members `CGIOperandList::OperandInfo` (#140625)

2025-05-21T13:23:01+00:00

- Change `Name`, `SubopNames`, `PrinterMethodName`, and
`EncoderMethodNames` to be stored as StringRef.
- Also changed `CheckComplexPatMatcher::Name` to StringRef as a fallout
from the above.

Verified that all the tablegen generated files within LLVM are
unchanged.

[NFC][TableGen] Use StringRef::str() instead of casting (#139332)

2025-05-12T22:41:27+00:00

- Also eliminate unneeded std::string() around some literal strings.

[TableGen] Add declarations to silence gcc warning. NFC (#125892)

2025-02-05T19:22:48+00:00

Add declarations of SDTypeConstraint's operator== and operator< to the
llvm namespace. These are declared as friends inside the class which
makes them part of the enclosing namespace, but gcc wants it to be more
explicit.

Fixes #125537.

[TableGen] Add a backend generating SDNode descriptions (#123002)

2025-01-22T06:01:08+00:00

This patch adds a simplistic backend that gathers all target-specific
SelectionDAG nodes and emits descriptions for most of them.

This includes generating node enumeration, node names, and information
about node "prototype" that can be used to verify that a node is valid.

The patch also extends SDNode by adding target-specific flags, which are
also included in the generated tables.

Part of #119709,
[RFC](https://discourse.llvm.org/t/rfc-tablegen-erating-sdnode-descriptions/83627).
