Hello.
I've got a patch candidate that leverages partial linking for a couple of
selected object files.
I'm sending make all-host- jX results for my machine:
before: 3m18s (user 32m52s)

So why did you go from applying this per-file to multiple files?
When I did per-file for {gimple,generic}-match.c I hit the following issue with
lto.priv symbols:
/usr/lib64/gcc/x86_64-suse-linux/10/../../../../x86_64-suse-linux/bin/ld:

Please remember that not all targets support LTO so a fallback to a
non-partial-LTO build needs to be provided and automatically invoked
for those targets.
Sure, for now it's definitely going to be a opt-in, enabled by something like:
make PARTIAL_LTO=1

I've tested the patch and apparently it's not enough for
{gimple,generic}-match.o not clashing
in symbol names. Apparently there are more IPA clones that collide.
Leaving that for now.
