2002-07-15 Michael Matz <matz@suse.de>,
Daniel Berlin <dberlin@dberlin.org>,
Denis Chertykov <denisc@overta.ru>
Add a new register allocator.
* ra.c: New file.
* ra.h: New file.
* ra-build.c: New file.
* ra-colorize.c: New file.
* ra-debug.c: New file.
* ra-rewrite.c: New file.
* Makefile.in (ra.o, ra-build.o, ra-colorize.o, ra-debug.o,
(ra-rewrite.o): New .o files for libbackend.a.
(GTFILES): Add basic-block.h.
* toplev.c (flag_new_regalloc): New.
(f_options): New option "new-ra".
(rest_of_compilation): Call initialize_uninitialized_subregs()
only for the old allocator. If flag_new_regalloc is set, call
new allocator, instead of local_alloc(), global_alloc() and
friends.
* doc/invoke.texi: Document -fnew-ra.
* basic-block.h (FOR_ALL_BB): New.
* config/rs6000/rs6000.c (print_operand): Write small constants
as @l+80.
* df.c (read_modify_subreg_p): Narrow down cases for a rmw subreg.
(df_reg_table_realloc): Make size at least as large as max_reg_num().
(df_insn_table_realloc): Size argument now is absolute, not relative.
Changed all callers.
* gengtype.c (main): Add the pseudo-type "HARD_REG_SET".
* regclass.c (reg_scan_mark_refs): Ignore NULL rtx's.
2002-06-20 Michael Matz <matz@suse.de>
* df.h (struct ref.id): Make unsigned.
* df.c (df_bb_reg_def_chain_create): Remove unsigned cast.
2002-06-13 Michael Matz <matz@suse.de>
* df.h (DF_REF_MODE_CHANGE): New flag.
* df.c (df_def_record_1, df_uses_record): Set this flag for refs
involving subregs with invalid mode changes, when
CLASS_CANNOT_CHANGE_MODE is defined.
2002-05-07 Michael Matz <matz@suse.de>
* reload1.c (fixup_abnormal_edges): Don't insert on NULL edge.
2002-05-03 Michael Matz <matz@suse.de>
* sbitmap.c (sbitmap_difference): Accept sbitmaps of different size.
Sat Feb 2 18:58:07 2002 Denis Chertykov <denisc@overta.ru>
* regclass.c (regclass): Work with all regs which have sets or
refs.
(reg_scan_mark_refs): Count regs inside (clobber ...).
2002-01-04 Michael Matz <matzmich@cs.tu-berlin.de>
* df.c (df_ref_record): Correctly calculate SUBREGs of hardregs.
(df_bb_reg_def_chain_create, df_bb_reg_use_chain_create): Only
add new refs.
(df_bb_refs_update): Don't clear insns_modified here, ...
(df_analyse): ... but here.
* sbitmap.c (dump_sbitmap_file): New.
(debug_sbitmap): Use it.
* sbitmap.h (dump_sbitmap_file): Add prototype.
2001-08-07 Daniel Berlin <dan@cgsoftware.com>
* df.c (df_insn_modify): Grow the UID table if necessary, rather
than assume all emits go through df_insns_modify.
2001-07-26 Daniel Berlin <dan@cgsoftware.com>
* regclass.c (reg_scan_mark_refs): When we increase REG_N_SETS,
increase REG_N_REFS (like flow does), so that regclass doesn't
think a reg is useless, and thus, not calculate a class, when it
really should have.
2001-01-28 Daniel Berlin <dberlin@redhat.com>
* sbitmap.h (EXECUTE_IF_SET_IN_SBITMAP_REV): New macro, needed for
dataflow analysis.
