[libc++][test] Use ASSERT_WITH_LIBRARY_INTERNAL_ALLOCATIONS in more places (#144339) ASSERT_WITH_LIBRARY_INTERNAL_ALLOCATIONS allows waiving asserts, for cases when we can't count allocations that happen within the libc++ shared library. When compiling with optimization, it is possible that some calls end up generated inline, where the overridden operator new/delete do get called (counting those calls), whereas the compiler may decide to leave some calls to the external definition (inside the shared library, where we can't count the calls). In particular, in one case, a non-optimized build calls _ZNSt3__112basic_stringIcNS_11char_traitsIcEENS_9allocatorIcEEED1Ev from the DLL, while it gets inlined (including direct calls to operator delete) when built with optimization. Therefore; for the cases where we can't count allocations internally within the library, waive these asserts. This fixes all testcases in mingw mode, when built with optimization enabled.
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.
