[llvm-objdump] -d: don't display mapping symbols as labels Similar to D96617 for llvm-symbolizer. This patch matches the GNU objdump -d behavior to suppress printing labels for mapping symbols. Mapping symbol names don't convey much information. When --show-all-symbols (not in GNU) is specified, we still print mapping symbols. Note: the `for (size_t SI = 0, SE = Symbols.size(); SI != SE;)` loops needs to iterate all mapping symbols, even if they are not displayed. We use the new field `IsMappingSymbol` to recognize mapping symbols. This field also enables simplification after D139131. ELF/ARM/disassemble-all-mapping-symbols.s is enhanced to add `.space 2`. If `End = std::min(End, Symbols[SI].Addr);` is not correctly set, we would print a `.word`. Reviewed By: jhenderson, jobnoorman, peter.smith Differential Revision: https://reviews.llvm.org/D156190
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.
