[CodeGen] Remove static member function Register::virtReg2Index. NFC (#127962)

2025-02-20T07:34:55+00:00

Use the nonstatic member instead.

I'm pretty sure the code in SPRIV is a layering violation. MC layer
files are using a CodeGen header.

[CodeGen] Use non-static Register::virtRegIndex() instead of static Register::virtReg2Index. NFC (#125031)

2025-01-30T08:14:08+00:00

These are the the ones where we already had a Register object being
used. Some places are still using unsigned which I did not convert.

[CodeGen][NewPM] Port `machine-block-freq` to new pass manager (#98317)

2024-07-12T07:45:01+00:00

- Add `MachineBlockFrequencyAnalysis`.
- Add `MachineBlockFrequencyPrinterPass`.
- Use `MachineBlockFrequencyInfoWrapperPass` in legacy pass manager.
- `LazyMachineBlockFrequencyInfo::print` is empty, drop it due to new
pass manager migration.

[WebAssembly] Add exnref type (#93586)

2024-05-28T23:10:11+00:00

This adds (back) the exnref type restored in the new EH proposal adopted
in Oct 2023 CG meeting:

[WebAssembly] Create separation between MC and CodeGen layers

2023-08-18T21:08:37+00:00

Move WebAssemblyUtilities from Utils to the CodeGen library. It
primarily deals in MIR layer types, so it really lives in the CodeGen
library.

Move a variety of other things around to try create better separation.

See issue #64166 for more info on layering.

Move llvm/include/CodeGen/WasmAddressSpaces.h back to
llvm/lib/Target/WebAssembly/Utils.

[WebAssembly] Add comments on local.tee transformation

2023-03-18T03:16:16+00:00

We have a good comment on `TEE` transformation in `RegStackify`:
https://github.com/llvm/llvm-project/blob/547e3456660000a16fc5c2a2f819f1a2b5d35b5d/llvm/lib/Target/WebAssembly/WebAssemblyRegStackify.cpp#L613-L632

And I think it can be helpful to have some more comments on how the
`TEE`s created in `RegStackify` are converted into `LOCAL_TEE`s.

Variable `OldReg` is changed to `DefReg` to be consistent with
`RegStackify`'s comment.

[WebAssembly] Fix debug locations for ExplicitLocals pass

2021-11-04T18:38:03+00:00

This is a reworked version of the reverted patch: https://reviews.llvm.org/D112487
Note that
a) it doesn't need the test changes anymore, and
b) I checked at least locally it passes other.test_pthread_lsan_leak
