I have started with experiments on czerny. Set --param inline-min-speedup from
8 to 15 at 30th of January and to 30 yesterday.
Most of size regression comes away with 15 and I observed to off-noise

Yes, I have started experiments with adjusting inliner limits: hopefully we can
tune up speedup limit because it is now applied more agresively (due to lack of
capping) and perhaps tune down size limits becaus

Unsure what to do about this bug -- things have gone back a bit but as you say
the cap introduced artificial limit back in times. But we do have
large-function-growth to limit big_speedup for large functio

Another experiment:
r255024: 741B
r255024 + patch r255103 + patch r256072: 752B
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83665

Ok, for the gromacs
r255102: .text size: 737B
r255103 + fix for sreal (r256072): .text size: 752B (+2.03%).
Honza can you please take a look?

Bisection of one or another example with the big_speedup_p fix manually patched
in would be appreciated I guess.

I see change in r256072 that increased .text in gromacs from:
83.6% 743Ki .text 743Ki 14.4%
to
83.8% 760Ki .text 760Ki 14.4%

One potential candidate is the ipa-inline big_speedup_p fix by Richard. It
does not seem to explain all the difference though. I have quickly checked that
it does affect gzip LTO binary, but less than reported
