[MemProf] Propagate size info used for hint reporting to duplicates (#172535) When we duplicate contexts (due to clones e.g. matching different inlined instances), we were propagating the allocation type but not the ContextSizeInfo, which is used for -memprof-report-hinted-sizes. This meant that we never reported hinting for any of the duplicated contexts, which can result in conservative results as in some cases only the duplicated contexts are able to be cloned and hinted. Note that this change could result in overly optimistic reporting in some cases.
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.
