* 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.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
