[PAC] Make ValueMapper handle ConstantPtrAuth values (#129088)

2025-02-28T20:48:01+00:00

Fix assertion failure when building PAuth-hardened code with LTO. W/o assertions we end with invalid codegen.

[DebugInfo] Map VAM args to `poison` instead of `undef` [NFC] (#122756)

2025-01-13T21:38:40+00:00

If an argument cannot be mapped in `Mapper::mapValue`, it can be mapped
to `poison` instead of `undef`.

[unittests] Use {} instead of std::nullopt to initialize empty ArrayRef (#109388)

Follow up to #109133.

[IR] Disallow ZeroInit for spirv.Image (#73887)

2023-12-19T05:54:25+00:00

According to spirv spec, OpConstantNull's result type can't be image
type. So we can't generate zeroinitializer for spirv.Image.

[ValueMapper] allow mapping ConstantTargetNone to its layout type

2023-04-25T07:48:28+00:00

zeroinitializer is allowed for spirv TargetExtType.
This PR allows ValueMapper to map TargetExtType ConstantTargetNone to '0' constant of its layout type.

[ValueMapper] Preserve poison types during value mapping

2023-03-06T05:21:09+00:00

Poison needs to be treated directly during type remap otherwise
it will be considered an instance of undef.

[llvm/unittests] Use std::nullopt instead of None (NFC)

2022-12-03T06:10:37+00:00

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

[DebugInfo] ValueMapper impl for DIArgList respects IgnoreMissingLocals

2022-01-17T17:17:32+00:00

This patch fixes an issue in which SSA value reference within a
DIArgList would be unnecessarily dropped by llvm-link, even when
invoking on a single file (which should be a no-op). The reason for the
difference is that the ValueMapper does not refer to the
RF_IgnoreMissingLocals flag for LocalAsMetadata contained within a
DIArgList; this flag is used for direct LocalAsMetadata uses to preserve
SSA references even when the ValueMapper does not have an explicit
mapping for the referenced SSA value, which appears to always be the
case when using llvm-link in this manner.

ValueMapper: Rename RF_MoveDistinctMDs => RF_ReuseAndMutateDistinctMDs, NFC

2021-02-11T00:53:21+00:00

Rename the `RF_MoveDistinctMDs` flag passed into `MapValue` and
`MapMetadata` to `RF_ReuseAndMutateDistinctMDs` in order to more
precisely describe its effect and clarify the header documentation.

Found this while helping to investigate PR48841, which pointed out an
unsound use of the flag in `CloneModule()`. For now I've just added a
FIXME there, but I'm hopeful that the new (more precise) name will
prevent other similar errors.
