* ld-elfvsb/elfvsb.exp (support_protected): New variable. Check
and set to "yes" if the protected visibility is expected to
pass.
(visibility_run): Set expected to fail for the "protected"
and "protected_undef_def" tests only if $support_protected is
"no".
* ld-elfvsb/main.c (PROTECTED_CHECK): Check for the protected
visibility support if defined.
* ld-elfvsb/elfvsb.exp (visibility_run): Set expected failure
for "protected_undef_def".
* ld-elfvsb/main.c: Don't define HIDDEN_UNDEF_TEST when
PROTECTED_WEAK_TEST is defined.
Don't define PROTECTED_UNDEF_TEST when PROTECTED_WEAK_TEST is
defined.
Define PROTECTED_TEST when PROTECTED_UNDEF_TEST is defined.
* ld-elfvsb/sh1.c (visibility): Mark protected only if
PROTECTED_TEST, PROTECTED_UNDEF_TEST or PROTECTED_WEAK_TEST
is defined.
(visibility_var): Likewise.
* rs6000-tdep.c (DEFAULT_LR_SAVE): Move to config/*/tm-*.h.
(rs6000_gdbarch_init): Use generic_pc_in_call_dummy instead of
rs6000_pc_in_call_dummy.
* config/rs6000/tm-rs6000.h (DEFAULT_LR_SAVE): Move here from
rs6000-tdep.c.
* config/powerpc/tm-ppc-eabi.h: Remove various definitions
handled by multi-arched rs6000-tdep.c.
* 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.
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.
