Try changing inliner parameters, e.g. add --param=max-inline-insns-single=400 option to the commandline. (The default was switched from 400 to 200 in GCC-9)

So that people in community can really do some help, orelse we didn't even know what regression it is.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91433 --- Comment #2 from George Fan --- The compiler option for botan is "-fstack-protector -m64 -pthread -lbotan-2 -ldl -lrt", which the compiler option for crafty is "-pthread -lstdc++ -fprofile-use -lm". While the sub-architecture is coffee lake.

I assume you tested on x86_64-linux. What compile-flags did you use and what machine sub-architecture are you running on (in case phoronix uses -march=native).
