[SystemZ] Handle IR struct arguments correctly. (#169583)

- The size of the stack slot was previously computed in LowerCall() by using
  the original type, but that didn't work for a struct. Compute the size
  by looking at the VT of each part and the number of them instead.

- All the members of a struct have the same OrigArgIndex, so it doesn't work
  to assume that following parts belong to a split argument until another
  OrigArgIndex is encountered. Use the isSplit() and isSplitEnd() flags
  instead.

- Detect any scalar integer argumet >64 bits in CanLowerReturn() instead of
  just i128, in order to let all of them be passed on stack.

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
