SystemZ: Migrate to newer relocation specifier representation

2025-06-16T02:26:40+00:00

z/OS creates SystemZMCExpr objects (https://reviews.llvm.org/D153788)
while ELF doesn't. Define the SystemZMCAsmInfoGOFF hooks
instead of the legacy MCSpecifierExpr:: hooks.

SystemZ: Rename SystemZMCExpr::VK_ to SystemZ::S_

2025-06-16T01:59:16+00:00

Prepare for removing SystemZMCExpr. Adopt the newer naming convention
used by most other targets.

Move SystemZ-specific MCSymbolRefExpr::VariantKind to SystemZMCExpr::Specifier

2025-03-23T01:05:40+00:00

Similar to previous migration done for other targets (PowerPC, X86, ARM,
etc). Switch from the confusing VariantKind to Specifier, which aligns
with Arm and IBM AIX's documentation.

In addition, rename *MCExpr::getKind, which confusingly shadows the base class getKind.

In the future, relocation specifiers should be encoded as part of
SystemZMCExpr instead of MCSymbolRefExpr.

Update the file headers across all of the LLVM projects in the monorepo

2019-01-19T08:50:56+00:00

to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

[SystemZ] Support all TLS access models - CodeGen part

2015-02-18T09:13:27+00:00

The current SystemZ back-end only supports the local-exec TLS access model.
This patch adds all required CodeGen support for the other TLS models, which
means in particular:

- Expand initial-exec TLS accesses by loading TLS offsets from the GOT
  using @indntpoff relocations.

- Expand general-dynamic and local-dynamic accesses by generating the
  appropriate calls to __tls_get_offset.  Note that this routine has
  a non-standard ABI and requires loading the GOT pointer into %r12,
  so the patch also adds support for the GLOBAL_OFFSET_TABLE ISD node.

- Add a new platform-specific optimization pass to remove redundant
  __tls_get_offset calls in the local-dynamic model (modeled after
  the corresponding X86 pass).

- Add test cases verifying all access models and optimizations.

Move the llvm mangler to lib/IR.

This makes it available to tools that don't link with target (like llvm-ar).
