(struct gdbarch_tdep): Define.
Remove all unnecessary defines.
* remote-e7000.c ({PR,GBR,SR,MACL,VBR,MACH}_REGNUM): Define to -1,
for h8300 case.

runtime check instead.
(e7000_wait): Ditto.
* sh3-rom.c (sh3_supply_register): Use gdbarch_tdep to get the SSR
and SPC register numbers.
(sh3_regnames, sh3e_regnames): Don't specify a size.
* config/h8300/tm-h8300.h: Add comment.

bfd_elf_get_arch_size to bfd_get_arch_size.
|
|
|

* dwarf2read.c (dwarf2_empty_hash_tables): Renamed from
dwarf2_empty_die_ref_table; zero dwarf2_cached_types as well.
Update all callers.

* regcache.c (registers_changed, registers_fetched): Use
ARCH_NUM_REGS directly, eliminating an unnecessary variable.
This change adds pseudo-register capability to GDB.
Pseudo-registers are handled like registers, but they
don't come from or live on the target. They may be
aliases for an existing register, or they may be computed.
* defs.h (NUM_PSEUDO_REGISTERS): Define default of zero.
(ARCH_FETCH_PSEUDO_REGISTERS): Define default of no-op.
(ARCH_STORE_PSEUDO_REGISTERS): Define default of no-op.
# regcache.c (registers_changed): Mark pseudo-registers
invalid, as well as real registers.
(registers_fetched): Do not mark pseudo-registers as fetched
at the same time as other (real) registers.
(read_register_bytes): Fetch pseudo-registers (if any) from
the target architecture module instead of from the target.
(read_register_gen): Ditto.
(read_register): Ditto.
(write_register_bytes): Store pseudo-registers (if any) to
the target architecture module instead of to the target.
(write_register_gen): Ditto.
(write_register): Ditto.
(build_regcache): Allocate enough register_valid space for
pseudo-registers as well as normal (real) ones.

POINTER.
|
|
* command.c (do_setshow_command): Fix typo in var_auto_boolean
case.
|
|
all old style K&R function definitions to ISO-C.
(struct gdbarch_tdep): Add mips_abi_string.
(mips_gdbarch_init): Initialize.
(mips_dump_tdep): Print mips_abi_string and other values.
(mips_push_arguments): Add more detailed tracing.

from here.
(print_address_numeric): To here.
* TODO: Update.

read_register{,_pid}() to ULONGEST.
|
|
16 byte boundary. Align allocated argument space using
MIPS_STACK_ARGSIZE. Reserve space on stack for the struct return
and floating-point registers. Use fp_register_arg_p to determine
if float_argreg should be aligned.
|
|
* config/sh/tm-sh.h (STORE_RETURN_VALUE): Redefine as
sh_store_return_value().
* sh-tdep.c (sh_store_return_value): New function. Store the
value returned by a function into the appropriate register.

* sh-tdep.c (sh_skip_prologue): Before looking at the actual
instructions, try to see if the symbol table can be of help, by
calling after_prologue(). If this doesn't work, call
skip_prologue_hard_way().
(skip_prologue_hard_way): Renamed from sh_skip_prologue. Add some
more instruction pattern matching for pushing of arguments, and
manipulation of r14.
(after_prologue): New function. Use symbol table info to determine
the end of the prologue, if possible.

Move from this file into new file regcache.c.

equivalence.
(rank_one_type): Use strcmp instead of == to compare type names.
Don't swap parm with arg when checking TYPE_CODE_REF types.
* valops.c (find_overload_match): Fix indentation. Compare
parameter rankings to 0..9, 10..99, and 100+ instead of 0, 10,
and 100.

spelling.
(test_enums): New procedure. Move enum tests from end of script
to here. Set breakpoint on function name instead of line number.
* gdb.c++/misc.cc (ClassWithEnum): Move past Foo definitions.
(enums2): New marker function.
(enums1): New function.
(main): Call enums1(). Move enum tests to enums1().
