[SPIR-V] Implement OpSpecConstantOp with ptr-cast operation (#109979) This PR reworks implementation of OpSpecConstantOp with ptr-cast operation (PtrCastToGeneric, GenericCastToPtr). Previous implementation didn't take into account a lot of use cases, including multiple inclusion of pointers, reference to a pointer from OpName, etc. A reproducer is attached as a new test case. This PR also fixes wrong type inference for IR patterns which generate new virtual registers without SPIRV type. Previous implementation assumed always that result has the same address space as a source that is not the fact, and, for example, led to impossibility to emit a ptr-cast operation in the reproducer, because wrong type inference rendered source and destination with the same address space, eliminating translation of G_ADDRSPACE_CAST.
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.
Consult the Getting Started with LLVM page for information on building and running LLVM.
