[AsmPrinter] Always emit global equivalents if there is non-global uses (#145648) A case found from https://github.com/rust-lang/rust/issues/142752: https://llvm.godbolt.org/z/T7ce9saWh. We should emit `@bar_0` for the following code: ```llvm target triple = "x86_64-unknown-linux-gnu" @rel_0 = private unnamed_addr constant [1 x i32] [ i32 trunc (i64 sub (i64 ptrtoint (ptr @bar_0 to i64), i64 ptrtoint (ptr @rel_0 to i64)) to i32)] @bar_0 = internal unnamed_addr constant ptr @foo_0, align 8 @foo_0 = external global ptr, align 8 define void @foo(ptr %arg0) { store ptr @bar_0, ptr %arg0, align 8 ret void } ```
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.
