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, ...
