[Sema] Note member decl when initializer list default constructs member (#121854)
Recently I had a scenario where I had:
1. A class C with many members m_1...m_n of the same type T
2. T's default constructor was deleted
3. I accidentally omitted an explicitly constructed member in the
initializer list C() : m_1(foo), m_2(bar), ... { }
Clang told me that T's default constructor was deleted, and told me that
the call to T() was in C() (which it implicitly was), but didn't tell me
which member was being default constructed.
It was difficult to fix this problem because I had no easy way to list
all the members of type T in C and C's superclasses which would have let
me find which member was missing,
clang/test/CXX/class/class.init/p1.cpp is a simplified version of this
problem (a2 is missing from the initializer list of B)
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.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
