[ASan] Honor `allocator_may_return_null` when set through user-function and fix large alloc edge case (#117929) **Related:** #117925 **About this PR:** This PR performs 3 small but related fixes for ASan users on Windows: 1. It ensures that the `allocator_may_return_null` flag is honored when set through the user function `__asan_default_options`. For more details, please see: #117925 2. It adds a missing `AllocatorMayReturnNull()` check inside `InternalAlloc` that's needed to avoid error'ing out when the allocator _correctly_ returns `null` when `allocator_may_return_null` is set. 3. In `sanitizer_win`'s `ReturnNullptrOnOOMOrDie`, it allows returning `null` when the last error is set to `ERROR_INVALID_PARAMETER` which may be set by `VirtualAlloc` on WIndows when attempting to allocate exceedingly large memory. I've added test cases that should cover these new behaviors. Happy to take on any feedback as well. Thank you :-) --------- Co-authored-by: David Justo <dajusto@microsoft.com>
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.
