| ## `@GLOBAL_SOURCE_ROOT@` and `@DIRNAME@` in machine files |
| |
| Some tokens are now replaced in the machine file before parsing it: |
| - `@GLOBAL_SOURCE_ROOT@`: the absolute path to the project's source tree |
| - `@DIRNAME@`: the absolute path to the machine file's parent directory. |
| |
| It can be used, for example, to have paths relative to the source directory, or |
| relative to toolchain's installation directory. |
| ```ini |
| [binaries] |
| c = '@DIRNAME@/toolchain/gcc' |
| exe_wrapper = '@GLOBAL_SOURCE_ROOT@' / 'build-aux' / 'my-exe-wrapper.sh' |
| ``` |
