Without a linker script, `--orphan-handling=error` or `=warn` reports all input sections, including even well-known sections like `.text`, `.bss`, `.dynamic`, or `.symtab`. However, in this case, no sections should be considered orphans because they all are placed with the same default rules. This patch suppresses errors/warnings for placing orphan sections if no linker script with the `SECTIONS` command is provided. The proposed behavior matches GNU gold. GNU ld in the same scenario only reports sections that are not in its default linker script, thus, it avoids complaining about `.text` and similar.
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.
