           Summary: The mod vpt does not work on PPC
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Keywords: pessimizes-code, patch
          Severity: enhancement
          Priority: P2
         Component: optimization
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: pinskia at gcc dot gnu dot org
                CC: gcc-bugs at gcc dot gnu dot org
GCC target triplet: powerpc-*-*

This is to keep track of two patches: <http://gcc.gnu.org/ml/gcc-patches/2003-10/
msg02412.html> and <http://gcc.gnu.org/ml/gcc-patches/2003-10/msg02414.html> which 
have the mod Value based feeedback work on PPC and other targets that do not have a MOD or an 
UMOD rtl.  Note I will fix up the first patch to use find_reg_equiv_note instead.

Waiting to VPT is implemented on the tree level, then this does not need to happen at all.

Fixed in 4.1.0 by:
2005-03-29  Dale Johannesen <dalej@apple.com>

        * Makefile.in (value-prof.o): New dependencies on $(DIAGNOSTIC_H)
        $(TREE_H) and $(COVERAGE_H).
        * coverage.c (compute_checksum): Use DECL_NAME not DECL_ASSEMBLER_NAME.
        * opts.c (common_handle_option): Enable tree-based value transforms.
        * toplev.c (process_options): Ditto.
        * value-prof.h (struct histogram_value_t): Redefine. "Adjust" below
        refers to references to this type.
        * tree-flow.h: (struct stmt_ann_d): Add histograms field.
        * rtl-profile.c (rtl_gen_interval_profiler): Adjust. Remove checks
        for may_be_more, may_be_less.
        (rtl_gen_pow2_profiler): Adjust.
        (rtl_gen_one_value_profiler_no_edge_manip): Adjust.
        (rtl_gen_one_value_profiler): Adjust.
        (rtl_gen_const_delta_profiler): Adjust.
        * tree-profile.c (tree_gen_interval_profiler): Implement.
        (tree_gen_pow2_profiler): Ditto.
