731 * mn10200-tdep.c: New file.
732 * config/mn10200/tm-mn10200.h: New, REGISTER_SIZE is 24 bits not 32,
733 SP_REGNUM and FP_REGNUM are different, also no lar or lir.
734 * config/mn10200/mn10200.mt: New file.
735 * configure.tgt: add mn10200 entry.
739 * configure.in configure: Check if host has libdl if doing
744 * mn10300-tdep.c: Wrote/fixed implementations of
745 mn10300_frame_chain, mn10300_init_extra_frame_info,
746 mn10300_frame_saved_pc
747 * config/mn10300/tm-mn10300.h: Redefine INIT_EXTRA_FRAME_INFO
748 and INIT_FRAME_PC macros.
752 * configure.in configure: Check if host has libm. Make sure we
753 are using gcc when using the -export-dynamic option. Fixes a
754 problem with building under Solaris/SunPro cc.
758 * config/mips/{embed,embed64,embedl,embedl64}.mt:
759 Link in simulator on MIPS embedded targets.
763 * blockframe.c (frameless_look_for_prologue): Mark frames
764 with a zero PC as frameless to improve backtraces from core dumps
765 caused by dereferencing a NULL function pointer.
769 * config/mn10300/tm-mn10300.h: fix BREAKPOINT definition.
773 * mn10300-tdep.c: made a lot more generic, ripping out code
774 from copied target (no more mn10300_scan_prologue,
775 init_extra_frame_info, and mn10300_fix_call_dummy calls)
776 * config/mn10300/tm-mn10300.h: undefine INIT_EXTRA_FRAME_INFO
777 and INIT_FRAME_PC macros
781 * sparc-tdep.c (sparc_frame_find_saved_regs): Don't use
782 FP_REGISTER_BYTES to compute offsets into the saved frame,
783 since it fails for SPARC targets configured without any
784 FP regs. Instead, use DUMMY_STACK_REG_BUF_SIZE.
788 * symtab.c (fixup_symbol_section): Handle NULL symbols without
793 * Makefile.in configure configure.in: Remove ENABLE_CLIBS,
794 ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS

807 instead of read_memory. It takes a bfd_section arg.
808 * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove
809 unnecessary cast for assignment of struct dbx_symfile_info.
810 Struct objfile now uses a real pointer instead of PTR for this
812 * dbxread.c (dbx_symfile_init): Stash bfd section pointers for
813 text, data and bss into dbx_symfile_info.
814 * exec.c (xfer_memory): Handle transfers for user-specified

824 * (print_formatted x_command): Record current section along with
825 current address for repeated commands.
826 * sparc-nat.c (fetch_inferior_registers): Change
827 target_xfer_memory to target_{read write}_memory to allow changes
828 to target_xfer_memory interface for section info.
829 * symmisc.c (dump_msymbols print_symbol): Print section
830 assocaited with symbol.
831 * symtab.c (fixup_symbol_section): New routine to
832 add section info to symbols returned by lookup_symbol.
833 * symtab.h (struct general_symbol_info): Add bfd section to

839 * (target_memory_bfd_section): New global variable to pass bfd
840 section in to targets.
841 * valarith.c (value_add value_addr value_array): Preserve bfd
842 section when computing new value.
843 * value.h (struct value): Add bfd section to values.
844 * values.c (allocate_value value_copy): Initialize/preserve bfd
846 * (unpack_double): Clean up _MSC_VER conditionals to remove

860 * config/mn10300/tm-mn10300.h: ripped out RP_REGNUM, V0_REGNUM,
861 ARG0_REGNUM, ARGLAST_REGNUM (all not appropriate for mn10300
862 arch.), redefined SAVED_PC_AFTER_CALL, EXTRACT_RETURN_VALUE,
863 EXTRACT_STRUCT_VALUE_ADDRESS, STORE_RETURN_VALUE.
