Revert change for revision.

Fix typo in ChangeLog entry.

* ppc-linux-tdep.c (ppc64_linux_bfd_entry_point): New function.
(ppc_linux_init_abi): Register it as our bfd_entry_point address.

* gdbarch.sh (gdbarch_bfd_entry_point): New gdbarch method.
* arch-utils.c (generic_bfd_entry_point): New function.
* arch-utils.h (generic_bfd_entry_point): New declaration.
* gdbarch.c, gdbarch.h: Regenerated.
* solib-svr4.c (enable_break): Call it, instead of accessing
tmp_bfd->start_address directly.

Revert patch for revision.

* ppc-linux-tdep.c (ppc64_linux_convert_from_func_ptr_addr): New
function.
(ppc_linux_init_abi): Register it as the
CONVERT_FROM_FUNC_PTR_ADDR method under the PPC64 Linux ABI.

Revert for revision.

Revert call to set_gdbarch_long_double_bit; rs6000-tdep.c handles this
correctly.

* gdbarch.sh (gdbarch_bfd_entry_point): New gdbarch method.
* arch-utils.c (generic_bfd_entry_point): New function.
* arch-utils.h (generic_bfd_entry_point): New declaration.
* gdbarch.c, gdbarch.h: Regenerated.
* solib-svr4.c (enable_break): Call it, instead of accessing
tmp_bfd->start_address directly.

* solib-svr4.c (solib_break_names): Recognize the 64-bit PowerPC
Linux entry point symbols for _dl_debug_state, too.

* solib-svr4.c (bfd_lookup_symbol): New SECT_FLAGS argument.
(enable_break): Pass SEC_CODE as the SECT_FLAGS argument to
bfd_lookup_symbol, since we only want symbols in code sections.
(look_for_base): Pass zero as the SECT_FLAGS argument to
bfd_lookup_symbol, since we're not concerned about which section
the symbol is in.

* ppc-linux-tdep.c (ppc64_linux_convert_from_func_ptr_addr): New
function.
(ppc_linux_init_abi): Register it as the
CONVERT_FROM_FUNC_PTR_ADDR method under the PPC64 Linux ABI.

* ppc-linux-tdep.c (ppc_linux_init_abi): long doubles are 16 bytes
long.

* arch-utils.c (always_use_struct_convention): New function.
* arch-utils.h (always_use_struct_convention): New prototype.
* alpha-tdep.c (alpha_use_struct_convention): Delete.
(alpha_gdbarch_init): Register always_use_struct_convention,
instead of alpha_use_struct_convention.
* cris-tdep.c (cris_use_struct_convention): Delete.
(cris_gdbarch_init): Register always_use_struct_convention,
instead of cris_use_struct_convention.
* frv-tdep.c (frv_use_struct_convention): Delete.
(frv_gdbarch_init): Register always_use_struct_convention,
instead of frv_use_struct_convention.
* h8300-tdep.c (h8300_use_struct_convention): Delete.
(h8300_gdbarch_init): Register always_use_struct_convention,
instead of h8300_use_struct_convention.
* mips_o32-tdep.c (mips_o32_use_struct_convention): Delete.
(mips_o32_gdbarch_init): Register always_use_struct_convention,
instead of mips_o32_use_struct_convention.

* ppc-linux-tdep.c (ppc64_call_dummy_address): New function.
(ppc_linux_init_abi): Set it as the gdbarch's call_dummy_address
method.

* ppc-linux-tdep.c (ppc64_desc_entry_point): New function.
(ppc64_standard_linkage_target): Use it.

Recognize and skip 64-bit PowerPC Linux linkage functions.
* ppc-linux-tdep.c (insn_d, insn_ds, insn_xfx, read_insn, struct
insn_pattern, insns_match_pattern, d_field, ds_field): New
functions, macros, and types for working with PPC instructions.
(ppc64_standard_linkage, PPC64_STANDARD_LINKAGE_LEN,
ppc64_in_solib_call_trampoline, ppc64_standard_linkage_target,
ppc64_skip_trampoline_code): New functions, variables, and macros
for recognizing and skipping linkage functions.
(ppc_linux_init_abi): Use ppc64_in_solib_call_trampoline and
ppc64_skip_trampoline_code for the 64-bit PowerPC Linux ABI.

* ppc-linux-nat.c (ppc_register_u_addr): Correctly compute u-area
offsets for floating-point registers in both 32- and 64-bit
interfaces.

insn_pattern, insns_match_pattern, d_field, ds_field): New
functions, macros, and types for working with PPC instructions.
(ppc64_standard_linkage, PPC64_STANDARD_LINKAGE_LEN,

Use gdbarch methods for solib stuff on PowerPC Linux.
* config/powerpc/tm-linux.h (IN_SOLIB_CALL_TRAMPOLINE,
SKIP_TRAMPOLINE_CODE): #undef these, so the gdbarch methods will
show through. Remove later #definition of SKIP_TRAMPOLINE_CODE.
(ppc_linux_skip_trampoline_code): Delete declaration.
* ppc-linux-tdep.c (ppc_linux_init_abi): Register
IN_SOLIB_CALL_TRAMPOLINE and SKIP_TRAMPOLINE_CODE methods here,
giving the same effect as the #definitions above.
(ppc_linux_skip_trampoline_code): Make this static.
