# Compiler extra flags
It is possible to add compiler flags for the entire build by wrapping toolchain binaries in script and hardlinking them.
### How to install
1. Build the toolchain
2. Move original binaries from `toolchain/out/bin` to `toolchain/out/bin_original`
3. Copy `wrapper.sh` and `setup_hardlinks.sh` to `toolchain/out/bin`
4. Execute `setup_hardlinks.sh`
5. Edit compiler and linker flags (`-O3` by default) in `wrapper.sh` to suit your needs
