------- Additional Comments From rakdver at gcc dot gnu dot org 2004-12-19 22:04 ------- With minor adjustment in ivopts, we get the same code as in 3.3 with fno-split- ivs-in-unroller, and more reasonably looking code without; I'm testing the patch just now.
Of course we cannot have autoincrements and iv splitting at the same time. It might be possible to use some heuristics to disable iv splitting if it does not seem useful. Possibly even better would be to add generation of autoincrements to loop optimizer, but this would require fixing cse so that it handles them correctly. -- What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |rakdver at gcc dot gnu dot |dot org |org Status|NEW |ASSIGNED http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19078
