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.
