--- Comment #4 from Fangrui Song <i at maskray dot me> ---
https://sourceware.org/pipermail/gcc-patches/2020-July/550659.html [PATCH v3]
Add --ld-path= to specify an arbitrary executable as the linker
I changed the title to --ld-path because -fuse-ld=/absolute/path/to/ld is not a
good design. -fuse-ld= can mean the linker flavor (there can be option dispatch
on this option) & --ld-path can specify the path overriding -fuse-ld='s default
choice.
-f* options are usually about code generation or language features. --ld-path
does not belong to the category so -f is not very appropriate.
Clang 12 will have --ld-path.

There are people wanting to use mold
https://www.reddit.com/r/rust/comments/rhcnzt/mold_a_modern_linker_10_release/
"clang does support it but gcc: --ld-path patch has been declined by GCC
maintainers, instead they advise to use a workaround: create directory
<dirname>, then ln -s <path-to-mold> <dirname>/ld, and then pass -B<dirname>
(-B tells GCC to look for ld in specified location)."

I agree that's unfortunate. 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.

-- 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...
