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.

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.

[Target] Remove unused forward declarations (NFC)

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.

Canonicalize header guards into a common format.

2014-08-13T16:26:38+00:00

Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

Re-sort all of the includes with ./utils/sort_includes.py so that

subsequent changes are easier to review. About to fix some layering
issues, and wanted to separate out the necessary churn.

Also comment and sink the include of "Windows.h" in three .inc files to
match the usage in Memory.inc.

[SystemZ] Define the call instructions as pseudo aliases.

2013-09-25T10:37:17+00:00

Similar to r191364, but for calls.  This patch also removes the shortening
of BRASL to BRAS within a TU.  Doing that was a bit controversial internally,
since there's a strong expectation with the z assembler that WYWIWYG.

[SystemZ] Fix parsing of inline asm registers

2013-07-12T09:08:12+00:00

GPR and FPR constraints like "{r2}" and "{f2}" weren't handled correctly
because the name-to-regno mapping depends on the value type and
(because of that) the internal names in RegStrings are not the
same as the AsmName.

CC constraints like "{cc}" didn't work either because there was no
associated register class.

[SystemZ] Add back end

2013-05-06T16:15:19+00:00

This adds the actual lib/Target/SystemZ target files necessary to
implement the SystemZ target.  Note that at this point, the target
cannot yet be built since the configure bits are missing.  Those
will be provided shortly by a follow-on patch.

This version of the patch incorporates feedback from reviews by
Chris Lattner and Anton Korobeynikov.  Thanks to all reviewers!

Patch by Richard Sandiford.
