The LLVM Project is a collection of modular and reusable compiler and toolchain technologies.
Hi all, I just discovered that the implementation of GNU statement expressions differs from GCC in C++ mode. The following C++ code compiles in GCC but not in Clang: ```cpp...
When InstCombine sees an addition of two sign-extended values and can prove that the addition won't overflow if done with the original width, it transforms the code to perform the...
Clang fails on this code with ```-std=c++20```: ```c++ template T nnn() { return 0; } void x() { nnn(); } ``` error: ```console testcase.cpp:8:2: error: no matching function for call...
For a given code in `foo.c` file ```c int foo() { some_type *bar; } ``` `clang` gives a cascade of confusing diagnostics: ```console foo.c:2:3: error: use of undeclared identifier 'some_type'...
Consider this C++17 code, which compiles fine with GCC but fails with Clang (at least Clang 9 to Clang 15). It is an MWE that I condensed from GCC's STL...
It seems like `ld.lld` will accept armeb input files, but proceeds to handle the relocations in little-endian (?) and silently produces invalid encodings for branches: ```console $ clang --target=armebv5te-none-eabi -mcpu=arm926ej-s...

Clang supports `-u` as a linker flag that accepts an argument: https://github.com/llvm/llvm-project/blob/aa5bc41b765694696ff05c3448247f7525577657/clang/include/clang/Driver/Options.td#L4258 Clang handles that option as a `JoinedOrSeparate` option which means that there does not need to be whitespace...

Here's a slightly modified version of a function found in the LLVM test suite: ```llvm define i32 @f(i32 %0) { %2 = ashr i32 %0, 32 %3 = freeze i32...
