``` SanitizerCommon-ubsan-sparc-Linux :: Linux/signal_send.cpp ``` currently `FAIL`s on Linux/sparc64 (32 and 64-bit). Instead of the expected values for `SIGUSR1` (`10`) and `SIGUSR1` (`12`), that target uses `30` and `31`. On Linux/x86_64, the signals get their values from `x86_64-linux-gnu/bits/signum-generic.h`, to be overridden in `x86_64-linux-gnu/bits/signum.h`. On Linux/sparc64 OTOH, the definitions are from `sparc64-linux-gnu/bits/signum-arch.h` and remain that way. There's no `signum.h` at all. The patch allows for both values. Tested on `sparc64-unknown-linux-gnu` and `x86_64-pc-linux-gnu`.
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.
