tree-sra.c (struct access): Rename total_scalarization to grp_total_scalarization
2011-06-30 Martin Jambor <mjambor@suse.cz>
* tree-sra.c (struct access): Rename total_scalarization to
grp_total_scalarization
(completely_scalarize_var): New function.
(sort_and_splice_var_accesses): Set total_scalarization in the
representative access.
(analyze_access_subtree): Propagate total scalarization accross the
tree, no holes in totally scalarized trees, simplify coverage
computation.
(analyze_all_variable_accesses): Call completely_scalarize_var instead
of completely_scalarize_record.
While it could be possible to output_set_got such that we can
individually annotate the instructions, it's simpler to simply
admit that all processors currently being manufactured do want
deep branch prediction. At which point all of the complication
simply goes away.
* config/i386/i386.h (X86_TUNE_DEEP_BRANCH_PREDICTION): Remove.
(TARGET_DEEP_BRANCH_PREDICTION): Remove.
* config/i386/i386.c: Don't include dwarf2out.h.
(initial_ix86_tune_features): Remove X86_TUNE_DEEP_BRANCH_PREDICTION.
(output_set_got): Don't test TARGET_DEEP_BRANCH_PREDICTION, delete
all code dead thereafter. Don't do dwarf2out_flush_queued_reg_saves.
(ix86_expand_prologue): Set REG_CFA_FLUSH_QUEUE on set_got insn.
(machopic_output_stub): Don't test TARGET_DEEP_BRANCH_PREDICTION.

dwarf2out_frame_debug before the insn if found.
* dwarf2out.c (struct reg_saved_in_data): Provide a typedef.
