[NFC][TableGen] Add accessors for various instruction subclasses (#146615)

2025-07-02T19:49:27+00:00

- Add various instruction subclass/sub-slice accessors to
`CodeGenTarget`.
- Delete unused `inst_begin` and `inst_end` iterators.
- Rename `Instructions` to `InstructionMap` and `getInstructions` to
`getInstructionMap` to better represent their meaning.
- Use these new accessors in InstrInfoEmitter

[NFC][TableGen] Use ArrayRef instead of const vector reference (#145323)

2025-06-24T14:30:00+00:00

- Use `ArrayRef` instead of `SmallVector` reference in a few places.
- Drop redundant `llvm::` in a few places.

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

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

[TableGen] Use `contains` instead of `count`. NFC. (#143156)

2025-06-07T08:31:42+00:00

[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.

[NFC][TableGen] Add {} for `else` when `if` body has {} (#139420)

2025-05-12T15:34:12+00:00

[TableGen] Avoid repeated hash lookups (NFC) (#126433)

2025-02-09T21:35:58+00:00

[TableGen] Add a SmallPtrSet to track WriteRes that are referenced by some ReadAdvance. NFC (#124160)

2025-01-23T20:48:59+00:00

Use this to remove a linear scan from CodeGenProcModel::hasReadOfWrite.

This reduces build time of RISCVGenSubtargetInfo.inc on by machine from
~6 seconds to ~3 seconds.

[TableGen] Pass CodeGenProcModel reference instead of index to addWriteRes/addReadAdvance. NFC

2025-01-23T17:11:29+00:00

2 of the 3 callers of each of these already had a reference they
converted to index. Use that reference and make the one caller
that only has an index responsible for looking up the reference from it.

[TableGen] Add maps from Write/ReadType to the parent WriteRes/ReadAdvance. NFC (#123876)

2025-01-22T21:41:42+00:00

Use this to improve performance of SubtargetEmitter::findWriteResources
and SubtargetEmitter::findReadAdvance. Now we can do a map lookup
instead of a linear search through all WriteRes/ReadAdvance records.
    
This reduces the build time of RISCVGenSubtargetInfo.inc on my
machine from 43 seconds to 10 seconds.
