defined before the statement using DEFINED yield 1.
* ldexp.c (fold_name) <case DEFINED>: In lang_first_phase_enum,
call lang_track_definedness on symbol. In subsequent phases, use
lang_symbol_definition_iteration and lang_statement_iteration to
check whether the symbol was defined before the current statement.
(exp_fold_tree) <case etree_assign et al>: Call
lang_update_definedness before updating symbol type when setting
symbol.
* ldlang.c (lang_definedness_table): New variable.
(lang_definedness_newfunc, lang_track_definedness)
(lang_symbol_definition_iteration, lang_update_definedness): New
functions.
(lang_init): Initialize lang_definedness_table and
lang_statement_iteration.
(lang_finish): Destroy bfd_hash_table_free.
(lang_size_sections): Increment lang_statement_iteration.
(lang_do_assignments_1): New function with former
lang_do_assignments contents. Change recursive calls to call this
function.
(lang_do_assignments): Evacuate contents. Increment
lang_statement_iteration, then just call lang_do_assignments_1.
* ldlang.h (struct lang_definedness_hash_entry)
(lang_statement_iteration, lang_track_definedness)
(lang_symbol_definition_iteration, lang_update_definedness):
Declare.
* gcore.c (make_mem_sec): Function removed, folded into ...
(gcore_create_callback): ... here. To omit a section, clear its
SEC_LOAD bit rather than zeroing its size.
Omit read-only sections only if they correspond to a known disk file.
(gcore_copy_callback): Ignore sections without SEC_LOAD flag set.
* rs6000-tdep.c (e500_store_return_value): Delete function.
(e500_extract_return_value): Delete function.
(rs6000_gdbarch_init): When SYSV, set "extract_return_value" and
"restore_return_value" to "ppc_sysv_abi_extract_return_value" and
"ppc_sysv_abi_restore_return_value" where applicable.
* ppc-tdep.h: (ppc_sysv_abi_store_return_value): Declare.
(ppc_sysv_abi_extract_return_value): Declare.
(ppc_sysv_abi_broken_store_return_value): Declare.
(ppc_sysv_abi_broken_extract_return_value): Declare.
(ppc_sysv_abi_broken_use_struct_convention:) Delete declaration.
* ppc-sysv-tdep.c (return_value_convention): Move definition to
start of file.
(do_ppc_sysv_return_value): New function.
(ppc_sysv_abi_extract_return_value): New function.
(ppc_sysv_abi_store_return_value): New function.
(ppc_sysv_abi_broken_extract_return_value): New function.
(ppc_sysv_abi_broken_store_return_value): New function.
(ppc_sysv_abi_use_struct_convention): Call
do_ppc_sysv_return_value.
* sim/frv/testutils.inc (or_gr_immed): New macro.
* sim/frv/fp_exception-fr550.cgs: Write insns using
unaligned registers into the program in order to
cause the required exceptions.
* sim/frv/fp_exception.cgs: Ditto.
* sim/frv/regalign.cgs: Ditto.
* Makefile.in (ppc-sysv-tdep.o): Add $(gdb_assert_h).
* rs6000-tdep.c (rs6000_gdbarch_init): When 64 bit SysV ABI, set
push_dummy_call to ppc64_sysv_abi_push_dummy_call.
* ppc-sysv-tdep.c: Include "gdb_assert.h".
(ppc64_sysv_abi_push_dummy_call): New function.
(ppc64_sysv_abi_broken_push_dummy_call): New function.
* ppc-tdep.h (ppc64_sysv_abi_push_dummy_call): Declare.
(ppc64_sysv_abi_broken_push_dummy_call): Declare.
* sh-tdep.c (sh_gdbarch_init): Delete setting of push_dummy_code.
(sh_gdbarch_init): Delete function, it's only used for dummy calls
on stack.
Based on input by Stephen Clarke (stephen.clarke@superh.com):
* sh-tdep.c (sh_use_struct_convention): Add comment explaining ABI
in detail.
