[SystemZ] Support PrintBranchImmAsAddress in disassembler (#141064)

As noticed in https://github.com/llvm/llvm-project/pull/140471, the
SystemZ target currently implements disassembly of PC-relative target
addresses differently from other back-ends. This patch brings SystemZ in
line with other targets.

Specifically, this patch changes the relevant MCInst instructions to
carry a PC-relative displacement instead of an absolute target address
in their immediate fields. When printing the instruction, this
displacement will either be shown as is (e.g. for llvm-mc), or else
translated into an absolute address at print time (e.g. for
llvm-objdump).

The existing llvm-mc based tests using PC-relative operands no longer
work and have to be rewritten, but printing displacements makes those
tests easier to maintain anyway.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch
