--- Comment #2 from Hans-Peter Nilsson <hp at gcc dot gnu.org> ---
Bisecting shows that revision r221859 is the culprit, adding Honza to CC.
I hope to add analysis of the compiled code showing (an example of) the
regressed code, but it would be really nice if Someone could
performance-regression test r221859 (compared to r221858) on another target.
Weird that a performance-regression of 16% is supposed to be *fixed* by that
commit (see PR65076). While it refers to *compile-time* regression, that is
just another name for a *run-time* performance-regression of the bootstrapped
compiler, apparently typical for at least the execution-path when compiling
tramp3d-v4.cpp supposedly for x86_64-linux and
26_numerics/random/negative_binomial_distribution/operators/values.cc for
cris-elf.
Note that the regression is not fixed for cris-elf at r222305 (a later
additional commit referencing PR65076).
Revision-numbers and cycle numbers while bisecting follows. Note the very
stable numbers:
r221618 34633750695
r221758 34633750695
r221828 34633750695

Something supposedly very good happened recently, because:
r223225 18369501023
I'll just have to find out what caused that 50% cut! The test-case is
unchanged.
If the cause is related to inlining heuristics, I'll close this PR for sure.
