[TableGen][MacroFusion] Predicate if the first inst has the same register (#137778) 2025-05-13T11:05:42+00:00 Pengcheng Wang wangpengcheng.pp@bytedance.com 2025-05-13T11:05:42+00:00 9570bf978d77aa53fffb50c60388da8f1bd71e4c We rename `SameReg` to `SecondInstHasSameReg ` and add `FirstInstHasSameReg ` which has the logic but applies to the first instruction. We have some cases that require the first instruction has the same input/output register.

Change `getValueAsListOfDefs` to return a vector of const Record
pointer, and remove `getValueAsListOfConstDefs` that was added as a
transition aid.

This is a part of effort to have better const correctness in TableGen
backends:

Adopt scaled indent in PredicateExpander.
Added pre/post inc/dec operators to `indent` and related unit tests.
Verified by comparing *.inc files generated by LLVM build with/without
the change.

This suppresses warning `unused variable 'MRI' [-Wunused-variable]`
for those fusions that don't need `MRI`.

Refactor of the llvm-tblgen source into:
- a "Basic" library, which contains the bare minimum utilities to build
`llvm-min-tablegen`
- a "Common" library which contains all of the helpers for TableGen
backends. Such helpers can be shared by more than one backend, and even
unit tested (e.g. CodeExpander is, maybe we can add more over time)

Fixes #80647

[MacroFusion] Support commutable instructions (#82751)

If the second instruction is commutable, we should be able to check
its commutable operands.

A simple RISCV fusion is contained in this PR to show the functionality
is correct, I may remove it when landing.

Fixes #82738

We should generate the `MCInstPredicate` twice, one with `FirstMI`
and another with `SecondMI`.
