Can you also try with --enable-checking=release to double check that it is not
the extra compile time checks which is causing issues ...

Note prev-gcc/cc1plus is compiled at -O0 also which definitely makes things
worse here.

I am not sure there is not much to be done here really since the issue is
profilingbootstrap will use -O0 for stage1 to make sure we don't run into bugs
in host compiler (though we still run into issues there).

--- Comment #8 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
Looks like it's mainly -O0.
Why not try to use at least -O1 for bootstrap? Perhaps it was a safe default to
workaround host compiler bugs in C days.
But nowadays gcc uses -std=c++11 with quite a bit of abstractions to remove at
-O0. Maybe having a disableable -O1 (or even default -O2) would be a better
default?

PRE : 444.33 ( 55%) 0.19 ( 4%) 444.86 ( 54%)
216k ( 0%)
There's a few other bugs about RTL PRE being slow (it's usually the dataflow
parts implemented with big sbitmaps and expression hashes). I've tried a
few times to get my hands into that but it's somewhat difficult.
For profile-generate we have a lot more memory ops which is what likely
kills us here (lots of bitmap iteration with disabled inlining/optimization).
Is this really a regression in GCC 14?
Note we are already using -fno-checking for building stage2.

--- Comment #11 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
Tried releases/gcc-12 branch and it's twice as bad: 20 minutes. Removing
`Regression` from the subject.

Yeah, ISTR I fixed the dataflow processing order in PREs LCM
(r14-131-ga322f37a57bc16), maybe that helped.

--- Comment #13 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note I also said in this commit:
"The LCM iteration has very many other issues ..."
but I don't exactly remember what I stumbled upon. Re-profiling (a release
checking, properly optimized compiler!) will point to bitmap stuff but the
actual iteration performing those is the interesting bit to look at.
