This fixes test errors like this, at least for a mingw target, if
building with Clang 21 instead of Clang 20, as in the CI environment:
# .---command stderr------------
# | error: 'expected-error' diagnostics seen but not expected:
# | File C:\a\llvm-mingw\llvm-mingw\llvm-project\libcxx\test\std\input.output\file.streams\c.files\gets-removed.verify.cpp Line 16: cannot initialize a parameter of type 'char *' with an lvalue of type 'const char *'
# | 1 error generated.
# `-----------------------------
# error: command failed with exit status: 1
This extra, unexpected diagnostic appears in Clang 21, since commit
9eef4d1c5fa6b1bcbbe675c14ca8301d5d346f7b ("Remove delayed typo
expressions"). Before this, we got the expected diagnostic `error: no
member named 'gets' in namespace 'std'`, with the typo correction hint
`did you mean 'puts'?`. After this change, we get the typo correction
hint `did you mean simply 'gets'?` instead. And with the typo correction
finding `::gets`, it goes on to produce a second diagnostic about
mismatched parameter for that function.
Avoid these unexpected diagnostics by passing the right type of
parameter to the gets function.
The LLVM Compiler Infrastructure
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.
