- Subject: [tree-ssa]: Add timevars for tree optimizers
Diego, thoughts?
Otherwise, this stuff gets thrown in "expand".
2002-10-21 Daniel Berlin <dberlin@dberlin.org>
* timevar.def: Add TV_TREE_{PRE,CCP,DCE,CFG,SSA} timevars.
* tree-optimize.c (optimize_function_tree): Push and pop timevars
for the tree optimizers.
