[CodeGen] Remove unused includes (NFC) (#115996)

2024-11-13T07:15:06+00:00

Identified with misc-include-cleaner.

[DwarfEhPrepare] Assign dummy debug location for more inserted _Unwind_Resume calls (#105513)

2024-08-22T15:13:20+00:00

Similar to the fix for #57469, ensure that the other `_Unwind_Resume`
call emitted by DwarfEHPrepare has a debug location if needed.

This fixes https://github.com/nbdd0121/unwinding/issues/34.

Reapply "[LLVM][LTO] Factor out RTLib calls and allow them to be dropped (#98512)"

2024-07-20T14:29:31+00:00

This reverts commit 740161a9b98c9920dedf1852b5f1c94d0a683af5.

I moved the `ISD` dependencies into the CodeGen portion of the handling,
it's a little awkward but it's the easiest solution I can think of for
now.

[LLVM][LTO] Factor out RTLib calls and allow them to be dropped (#98512)

2024-07-16T11:22:09+00:00

Summary:
The LTO pass and LLD linker have logic in them that forces extraction
and prevent internalization of needed runtime calls. However, these
currently take all RTLibcalls into account, even if the target does not
support them. The target opts-out of a libcall if it sets its name to
nullptr. This patch pulls this logic out into a class in the header so
that LTO / lld can use it to determine if a symbol actually needs to be
kept.

This is important for targets like AMDGPU that want to be able to use
`lld` to perform the final link step, but does not want the overhead of
uncalled functions. (This adds like a second to the link time trivially)

[NFC][RemoveDIs] Use iterators for insertion at various call-sites (#84736)

2024-03-19T16:36:29+00:00

These are the last remaining "trivial" changes to passes that use
Instruction pointers for insertion. All of this should be NFC, it's just
changing the spelling of how we identify a position.

In one or two locations, I'm also switching uses of getNextNode etc to
using std::next with iterators. This too should be NFC.

[CodeGen] Update DwarfEHPreparePass references in `CodeGenPassBuilder.h` (#74068)

2023-12-11T01:26:01+00:00

Forgot to update the counterpart in `CodeGenPassBuilder.h`. Also Rename `dwarfehprepare` -> `dwarf-eh-prepare`.

[CodeGen] Port DwarfEHPrepare to new pass manager (#72500)

[NFC] Remove Type::getInt8PtrTy (#71029)

2023-11-07T16:26:26+00:00

Replace this with PointerType::getUnqual().
Followup to the opaque pointer transition. Fixes an in-code TODO item.

[NFC][CodeGen] Change CodeGenOpt::Level/CodeGenFileType into enum classes (#66295)

2023-09-14T21:10:14+00:00

This will make it easy for callers to see issues with and fix up calls
to createTargetMachine after a future change to the params of
TargetMachine.

This matches other nearby enums.

For downstream users, this should be a fairly straightforward
replacement,
e.g. s/CodeGenOpt::Aggressive/CodeGenOptLevel::Aggressive
or s/CGFT_/CodeGenFileType::
