[lldb][Format] Display only the inlined frame name in backtraces if available (#135343) When a frame is inlined, LLDB will display its name in backtraces as follows: ``` * thread #1, queue = 'com.apple.main-thread', stop reason = breakpoint 1.3 * frame #0: 0x0000000100000398 a.out`func() [inlined] baz(x=10) at inline.cpp:1:42 frame #1: 0x0000000100000398 a.out`func() [inlined] bar() at inline.cpp:2:37 frame #2: 0x0000000100000398 a.out`func() at inline.cpp:4:15 frame #3: 0x00000001000003c0 a.out`main at inline.cpp:7:5 frame #4: 0x000000026eb29ab8 dyld`start + 6812 ``` The longer the names get the more confusing this gets because the first function name that appears is the parent frame. My assumption (which may need some more surveying) is that for the majority of cases we only care about the actual frame name (not the parent). So this patch removes all the special logic that prints the parent frame. Another quirk of the current format is that the inlined frame name does not abide by the `${function.name-XXX}` format variables. We always just print the raw demangled name. With this patch, we would format the inlined frame name according to the `frame-format` setting (see the test-cases). If we really want to have the `parentFrame [inlined] inlinedFrame` format, we could expose it through a new `frame-format` variable (e..g., `${function.inlined-at-name}` and let the user decide where to place things.
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.
