Remove GlobalObject::getAlign/setAlignment (#143188)

2025-06-09T20:51:03+00:00

Currently, GlobalObject has an "alignment" property... but it's
basically nonsense: alignment doesn't mean the same thing for variables
and functions, and it's completely meaningless for ifuncs.

This "removes" (actually marking protected) the methods from
GlobalObject, adds the relevant methods to Function and GlobalVariable,
and adjusts the code appropriately.

This should make future alignment-related cleanups easier.

[SystemZ] Add support for new cpu architecture - arch15

2025-01-20T18:30:21+00:00

This patch adds support for the next-generation arch15
CPU architecture to the SystemZ backend.

This includes:
- Basic support for the new processor and its features.
- Detection of arch15 as host processor.
- Assembler/disassembler support for new instructions.
- Exploitation of new instructions for code generation.
- New vector (signed|unsigned|bool) __int128 data types.
- New LLVM intrinsics for certain new instructions.
- Support for low-level builtins mapped to new LLVM intrinsics.
- New high-level intrinsics in vecintrin.h.
- Indicate support by defining  __VEC__ == 10305.

Note: No currently available Z system supports the arch15
architecture.  Once new systems become available, the
official system name will be added as supported -march name.

[Target] Remove unused includes (NFC) (#116577)

[IR] Add getDataLayout() helpers to Function and GlobalValue (#96919)

2024-06-28T06:36:49+00:00

Similar to https://github.com/llvm/llvm-project/pull/96902, this adds
`getDataLayout()` helpers to Function and GlobalValue, replacing the
current `getParent()->getDataLayout()` pattern.

[NFC] Remove unused parameter from shouldAssumeDSOLocal()

[SystemZ][NFC] Fix a couple of style issues (#69958)

2023-10-25T13:09:04+00:00

Some fixes for style issues pointed out by clang-tidy:

- Upper case/lower case fixes
- No else after return
- Removed unused #include's
- Added NOLINTNEXTLINE() for the LLVM* functions

All changes are NFC.

[SystemZ][z/OS] z/OS ADA codegen and emission

2023-07-05T17:21:52+00:00

This patch adds support for the ADA (associated data area), doing the following:

-Creates the ADA table to handle displacements
-Emits the ADA section in the SystemZAsmPrinter
-Lowers the ADA_ENTRY node into the appropriate load instruction
