Create .cargo/config.toml in your project directory with the following:
[target.x86_64-unknown-linux-gnu]
linker = “clang”
rustflags = [“-C”, “link-arg=-fuse-ld=/path/to/mold”]
where /path/to/mold is an absolute path to the mold executable. In the example above, we use clang as a linker driver since it always accepts the -fuse-ld option. If your GCC is recent enough to recognize the option, you may be able to remove the linker = “clang” line.
[target.x86_64-unknown-linux-gnu]
rustflags = [“-C”, “link-arg=-fuse-ld=/path/to/mold”]
If you want to use mold for all projects, add the above snippet to ~/.cargo/config.toml
Cool. Any idea how would i use this with rustc?
