Compare:
https://gcc.gnu.org/pipermail/gcc-testresults/2025-April/845489.html
(checking=yes,extra,rtl,df,gcac - shortly over 2 hours and 15 minutes)
with:
https://gcc.gnu.org/pipermail/gcc-testresults/2025-May/845705.html
(checking=yes,extra,rtl,df,gcac,fold - almost 7 hours wall clock time).
A large part of the difference is explained by one of the emit-insn-N.cc
files takes over an hour to compile (twice, of course) - mostly on its
own ...
In the manual "checking=fold" is not indicated as one of the checking
options that takes a lot of time ... but that was perhaps in the dim and
distant past.
Aside from that, the split of emit-insn.cc on AArch64 seems suboptimal -
perhaps someone can point me to the algorithm behind the splitting so
that I can experiment with it ?
Thanks in advance,
