Hello,
2012-08-19 Dimitrios Apostolou <ji...@gmx.net>
* gcc/cselib.c (cselib_init): Make allocation pools larger since
they are too hot and show to expand often on the profiler.
* gcc/df-problems.c (df_chain_alloc): Same.
* gcc/et-forest.c (et_new_occ, et_new_tree): Same.
* gcc/tree-ssa-pre.c (init_pre): Same
These allocation pools are the ones that I've noticed calling malloc() too
often, for expanding their size. Also I don't like the way the pools are
created in et_new_{occ,tree}() but couldn't find a single point to move
the initialisation either. Any ideas on this one?
Thanks,
Dimitris
