It used to be that LTO could quite increase linking time, is there some
visible compil time difference for lyx?
Yes, the link time is longer, but it seems that one can use -flto=4 to use
4 CPUS.
For reference, the configure line I used was:
../master/configure --enable-build-type=rel --with-version-suffix=-master
CXX='g++ -flto' AR='gcc-ar' RANLIB=gcc-ranlib LD='g++ -flto'
I could try to include that in configure (and test it with clang too).
I am excited to see how this flies on my 10y old laptop.
If no other mail comes it means I got swapped to death :)
I guess that memory is the difficult point.
