* Makefile.in configure configure.in: Remove ENABLE_CLIBS,
ENABLE_OBS, and THREAD_DB_OBS. These are consolidated into LIBS and CONFIG_OBS. * configure configure.in: Clean up test cases around thread support. start-sanitize-v850 * configure.tgt (v850-*-*): Include v850ice.o and v850.lib if host is Windows. end-sanitize-v850 * c-valprint.c ch-valprint.c cp-valprint.c eval.c expprint.c printcmd.c valops.c value.h values.c: Add bfd_section arg to value_at and value_at_lazy. * coffread.c dbxread.c elfread.c mdebugread.c minsyms.c symtab.h: Add bfd_section arg to prim_record_minimal_symbol_and_info. * corefile.c gdbcore.h printcmd.c valops.c: Use read_memory_section instead of read_memory. It takes a bfd_section arg. * coffread.c dbxread.c elfread.c gdb-stabs.h objfiles.h: Remove unnecessary cast for assignment of struct dbx_symfile_info. Struct objfile now uses a real pointer instead of PTR for this element. * dbxread.c (dbx_symfile_init): Stash bfd section pointers for text, data and bss into dbx_symfile_info. * exec.c (xfer_memory): Handle transfers for user-specified sections. * findvar.c (read_var_value locate_var_value): Copy bfd section from the symbol to the value. * gdb-stabs.h: Add section pointers for text, data and bss sections. * maint.c (translate address command): Add test code for overlay address translation. * printcmd.c (do_examine do_one_display): Now takes a bfd section arg. * (print_formatted x_command): Record current section along with current address for repeated commands. * sparc-nat.c (fetch_inferior_registers): Change target_xfer_memory to target_{read write}_memory to allow changes to target_xfer_memory interface for section info. * symmisc.c (dump_msymbols print_symbol): Print section assocaited with symbol. * symtab.c (fixup_symbol_section): New routine to add section info to symbols returned by lookup_symbol. * symtab.h (struct general_symbol_info): Add bfd section to symbols. * target.c target.h (target_xfer_memory): Add bfd section to args. * (target_read_memory_section): New routine to read data from a specific section. * (target_memory_bfd_section): New global variable to pass bfd section in to targets. * valarith.c (value_add value_addr value_array): Preserve bfd section when computing new value. * value.h (struct value): Add bfd section to values. * values.c (allocate_value value_copy): Initialize/preserve bfd section. * (unpack_double): Clean up _MSC_VER conditionals to remove duplicate code. start-sanitize-v850 * v850ice.c: New module to support communication with NEC's PC-based ICE. * config/v850/tm-v850.h (REGISTER_NAMES): Replace sp, gp, fp, and ep names with rxx names. sp and fp are renamed via a different mechanism. end-sanitize-v850
