[Bug tree-optimization/21831] [4.1 Regression] gcc.dg/vect/vect-97.c fails
--- Additional Comments From kbesaw at us dot ibm dot com 2005-06-06 23:45 --- I tried vect-97.c on power-pc and couldn't reproduce the problem. I don't know if this means that the problem goes away with recent patches or that it only occurs when vectorizing on ia64. I don't have the ability to build and test on ia64. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21831

My monitoring has never shown this as an i686-pc-linux-gnu failure, but it still fails on ia64-hpux, both -milp32 and -mlp64, as of today's mainline. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21831

--- Additional Comments From janis at gcc dot gnu dot org 2005-09-16 00:45 --- Test vect-97.c currently passes on ia64-linux and passed on alpha-dec-osf5.1b on 20050805, and the submitter said it passes on ia64-hpux; this PR can probably be closed. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21831

I.e., caused by: Changes by: [EMAIL PROTECTED] 2005-05-29 13:14:43 Modified files: gcc: ChangeLog tree-flow.h tree-optimize.c tree-ssa-alias.c tree-vect-transform.c Log message: 2005-05-29 Keith Besaw <[EMAIL PROTECTED]> * tree-ssa-alias.c (new_type_alias): New procedure to create a type memory tag for a pointer with a may-alias set determined from a variable declaration. * tree-flow.h: export declaration of new_type_alias * tree-optimize.c (init_tree_optimization_passes): document that pass_may_alias cannot be called after pass_vectorize. * tree-vect-transform (vect_create_data_ref_ptr): Call new_type_alias when an type memory tag isn't available for a reference. (vectorizable_store): Use copy_virtual_operands to update virtual defs in place (so that loop_version can be called). Call mark_for_renaming for the virtual defs in case peeling is done and virtual uses outside the loop need to be updated. The problem ought to be reproducible with a cross-compiler cc1. -- What|Removed |Added CC||dorit at gcc dot gnu dot ||org, kbesaw at us dot ibm ||dot com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21831
