[AMDGPU] gfx1250 64-bit relocations and fixups (#148951)

2025-07-16T00:13:42+00:00

MCFixup: Replace getTargetKind with getKind

2025-07-15T07:21:07+00:00

AMDGPU: Replace deprecated FK_PCRel_ with FK_Data_ fixup and PCRel flag

2025-07-05T05:45:52+00:00

We will unify the generic fixup kinds FK_Data_ and FK_PCRel_. A
FK_PCRel_ kind is essentially the corresponding FK_Data_ fixup with the
PCRel flag set.

ELFObjectWriter: Remove the MCContext argument from getRelocType

2025-05-25T04:48:11+00:00

Additionally, swap MCFixup/MCValue order to match addReloc/recordRelocation.

ELFObjectWriter: Replace Ctx.reportError with reportError

2025-05-25T04:11:17+00:00

Prepare for removing MCContext from getRelocType functions.

ELFObjectWriter: Make .reloc test generic

2025-04-13T06:02:24+00:00

Move `Fixup.getKind() >= FirstLiteralRelocationKind` from target hooks
to ELFObjectWriter::recordRelocation.

Currently, getRelocType cannot be skipped for LoongArch due to #135519

MCValue: Replace getAccessVariant with getSpecifier

2025-04-06T06:55:35+00:00

Commit 52eb11f925ddeba4e1b3840fd636ee87387f3ada temporarily introduced
getSymSpecifier to prepare for "MCValue: Replace MCSymbolRefExpr members
with MCSymbol" (d5893fc2a7e1191afdb4940469ec9371a319b114). The
refactoring is now complete.

[AMDGPU,MC] Replace getSymA()->getSymbol() with getAddSym. NFC

2025-04-05T21:04:00+00:00

We will replace the MCSymbolRefExpr member in MCValue with MCSymbol.
This change reduces dependence on MCSymbolRefExpr.

Move relocation specifiers to AMDGPUMCExpr::Specifier

2025-03-30T19:12:38+00:00

Similar to previous migration done for all other ELF targets.
Switch from the confusing `VariantKind` to `Specifier`, which aligns
with Arm and IBM AIX's documentation.

Moving forward, relocation specifiers should be integrated into
AMDGPUMCExpr rather than MCSymbolRefExpr::SubclassData.

(Note: the term AMDGPUMCExpr::VariantKind is for expressions
without relocation specifiers:
https://github.com/llvm/llvm-project/pull/82022

It's up to AMDGPU maintainers to integrate these constants into Specifier.

[AMDGPU] Add an asm directive to track code_object_version (#76267)

2024-01-21T16:54:47+00:00

Named '.amdhsa_code_object_version'. This directive sets the
e_ident[ABIVERSION] in the ELF header, and should be used as the assumed
COV for the rest of the asm file.

This commit also weakens the --amdhsa-code-object-version CL flag.
Previously, the CL flag took precedence over the IR flag. Now the IR
flag/asm directive take precedence over the CL flag. This is implemented
by merging a few COV-checking functions in AMDGPUBaseInfo.h.
