[OpenMP] Fixup bugs found during fuzz testing (#143455) A lot of these only trip when using sanitizers with the library. * Insert forgotten free()s * Change (-1) << amount to 0xffffffffu as left shifting a negative is UB * Fixup integer parser to return INT_MAX when parsing huge string of digits. e.g., 452523423423423423 returns INT_MAX * Fixup range parsing for affinity mask so integer overflow does not occur * Don't assert when branch bits are 0, instead warn user that is invalid and use the default value. * Fixup kmp_set_defaults() so the C version only uses null terminated strings and the Fortran version uses the string + size version. * Make sure the KMP_ALIGN_ALLOC is power of two, otherwise use CACHE_LINE. * Disallow ability to set KMP_TASKING=1 (task barrier) this doesn't work and hasn't worked for a long time. * Limit KMP_HOT_TEAMS_MAX_LEVEL to 1024, an array is allocated based on this value. * Remove integer values for OMP_PROC_BIND. The specification only allows strings and CSV of strings. * Fix setting KMP_AFFINITY=disabled + OMP_DISPLAY_AFFINITY=TRUE
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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
