See musl commit 05870abeaac0588fb9115cfd11f96880a0af2108 by Rich Felker. Commit message from musl reproduced here: fix code path where child function returns in arm __clone built as thumb mov lr,pc is not a valid way to save the return address in thumb mode since it omits the thumb bit. use a chain of bl and bx to emulate blx. this could be avoided by converting to a .S file with preprocessor conditions to use blx if available, but the time cost here is dominated by the syscall anyway. while making this change, also remove the remnants of support for pre-bx ISA levels. commit 9f290a49bf9ee247d540d3c83875288a7991699c removed the hack from the parent code paths, but left the unnecessary code in the child. keeping it would require rewriting two code paths rather than one, and is useless for reasons described in that commit. |

Building from Source
Note that you can download a binary of master branch.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 8.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 2.8.5
- Microsoft Visual Studio 2017 (version 15.8)
- LLVM, Clang, LLD development libraries == 8.x, compiled with the same MSVC version above
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install
MacOS
brew install cmake llvm@8
brew outdated llvm@8 || brew upgrade llvm@8
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
Windows

Stage 2: Build Self-Hosted Zig from Zig Source Code
Note: Stage 2 compiler is not complete. Beta users of Zig should use the Stage 1 compiler for now.
Dependencies are the same as Stage 1, except now you can use stage 1 to compile Zig code.
bin/zig build --prefix $(pwd)/stage2
This produces ./stage2/bin/zig which can be used for testing and development.
Once it is feature complete, it will be used to build stage 3 - the final compiler
binary.
Stage 3: Rebuild Self-Hosted Zig Using the Self-Hosted Compiler
Note: Stage 2 compiler is not yet able to build Stage 3. Building Stage 3 is not yet supported.
Once the self-hosted compiler can build itself, this will be the actual compiler binary that we will install to the system. Until then, users should use stage 1.
Debug / Development Build
./stage2/bin/zig build --prefix $(pwd)/stage3
Release / Install Build
./stage2/bin/zig build install -Drelease
