* tree-ssa-pre.c (do_regular_insertion): Only insert if a
redundancy along a path in the CFG we want to optimize for speed
is going to be removed.
(execute_pre): Do partial-PRE only if the function is to be
optimized for speed.
(gate_pre): Do not turn off all of PRE when not optimizing a
function for speed.
* gcc.dg/tree-ssa/ssa-pre-26.c: New testcase.
