The addition of v2f32 as a legal type, supported by the B64 register class, has caused performance regressions, broken inline assembly, and resulted in a couple (now fixed) mis-compilations. In order to mitigate these issues, only mark this as a legal type when there exist operations that support it, since for targets where this is not the case it serves no purpose. To enable further debugging, add an option to disable v2f32. In order to allow for a target-dependent set of legal types, ComputePTXValueVTs has been fully re-written to take advantage of TargetLowering call-lowering APIs.
The LLVM Compiler Infrastructure
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.
