* separate initialization routines into _start and do_start for all architectures. * lift do_start as a separate object library to avoid code duplication. * (addtionally) address the problem of building hermetic libc with -fstack-pointer-* The `crt1.o` is now a merged result of three components: ``` ___ |___ x86_64 | |_______ start.cpp.o <- _start (loads process initial stack and aligns stack pointer) | |_______ tls.cpp.o <- init_tls, cleanup_tls, set_thread_pointer (TLS related routines) |___ do_start.cpp.o <- do_start (sets up global variables and invokes the main 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.
Getting the Source Code and Building LLVM
