Note I'm having a patch that adds -fuse-ld=mold: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=759cdbb29dbe8fc80ba5c1f113a015cafe9eb69c I can try suggesting that to the community for GCC 12 (and maybe backport that). Are you interested? Note the linker is very interesting, but it lacks LTO support..

I think it may be useful to simply allow -fuse-ld=word (`word` cannot include a separator). If that may be troublesome, having -fuse-ld=mold in GCC 12 is still nice. --ld-path is occasionally useful, but I can accept that GCC declines it. > Note the linker is very interesting, but it lacks LTO support.. Right...

--- Comment #15 from Fangrui Song ---
-- is definitely rare, but not non-existent.
In GCC, there is {-,--}specs.
In Clang, there are --cuda-path, --ptxas-path, --hip-path, --classpath, etc.

I do not see an objection to -fuse-ld=word.
For --ld-path, -- is definitely rare, but not non-existent.
In GCC, there are {-,--}specs --sysroot.
In Clang, there are --cuda-path, --ptxas-path, --hip-path, --classpath, etc.
-fuse-ld= users mostly care about whether another linker can build their
programs, not whether the option can bootstrap GCC. I actually think ld.lld is
quite sufficient in bootstrapping GCC but if there are edge-case extensions
which not supported, ld.lld developers may not want to the project with more
obscure options...

Clang 12 will have --ld-path.
