Fetch varobj values from memory in a single place,
and only fetch the values that are really needed.
* varobj.c (struct varobj): Clarify comment.
(my_value_equal): Remove.
(install_new_value): New function.
(type_of_child): Remove.
(varobj_create): Use install_new_value.
(varobj_set_value): Use value_contents_equal, not
my_value_equal.
(varobj_update): Use install_new_value.
(create_child): Likewise. Inline type_of_child here.
(value_of_child): Don't fetch the value.
(c_value_of_root): Likewise.
(c_value_of_variable): Likewise.
(type_changeable): Improve comments.
(compare_pnums): New function.
(init_remote_state): Only allocate packet_reg structures for raw
registers. Define the g/G packet format separately from creating
packet_reg. Don't use DEPRECATED_REGISTER_BYTE.
(packet_reg_from_regnum, packet_reg_from_pnum): Only iterate over
raw registers.
(register_bytes_found): Delete.
(fetch_register_using_p): Take a struct packet_reg. Handle disabled
'p' packet here. Use packet_ok.
(fetch_registers_using_g): New function, split out of
remote_fetch_registers. Check the 'g' packet more strictly. Save
its actual size and contents. Eliminate BUF. Only iterate over
raw registers.
(remote_fetch_registers): Use the new functions for 'p' and 'g'.
Mark unavailable registers.
(store_register_using_P): Likewise to fetch_register_using_p.
(store_registers_using_G): New function, split out of
remote_store_registers. Only iterate over raw registers. Don't
use register_bytes_found.
(remote_store_registers): Likewise to remote_fetch_registers.
* coffread.c (cs_to_bfd_section): New function.
(cs_to_section): Use cs_to_bfd_section.
(record_minimal_symbol): Take the coff_symbol* parameter instead
of the symbol's name as a char*.
Add 'int section' parameter. Call prim_record_minimal_symbol_and_info
instead of prim_record_minimal_symbol_and_info.
Change return type to struct minimal_symbol *.
(coff_symtab_read): Adapt to new record_minimal_symbol's signature.
Make all minimal symbol creations go through record_minimal_symbol.
* elf32-xtensa.c (elf_xtensa_special_sections): Add .xtensa.info.
gas/
* config/tc-xtensa.c (XSHAL_ABI): Add default definition.
(directive_state): Disable scheduling by default.
(xtensa_add_config_info): New.
(xtensa_end): Call xtensa_add_config_info.
gas/testsuite/
* gas/elf/section2.e-xtensa: New file.
* gas/elf/elf.exp: Use it.
include/
* xtensa-config.h (XSHAL_ABI): New.
(XTHAL_ABI_WINDOWED, XTHAL_ABI_CALL0): New.
ld/
* emultempl/xtensaelf.em (XSHAL_ABI): Add default definition.
(replace_insn_sec_with_prop_sec): Use bfd_make_section_with_flags.
Delete redundant code to set sections flags and alignment.
(xt_config_info_unpack_and_check, check_xtensa_info): New.
(elf_xtensa_after_open): Iterate over input statements instead of
link_info.input_bfds.
(elf_xtensa_before_allocation): Likewise. Call check_xtensa_info for
each input, and write a new .xtensa.info section in the output.
* elf.c (IS_SECTION_IN_INPUT_SEGMENT): New.
(INCLUDE_SECTION_IN_SEGMENT): Use IS_SECTION_IN_INPUT_SEGMENT.
(rewrite_elf_program_header): Don't preserve segment physical
address in the output segment if the first section in the
corresponding input segment is removed.
* arm-dis.c (last_is_thumb): Delete.
(enum map_type, last_type): New.
(print_insn_data): New.
(get_sym_code_type): Take MAP_TYPE argument. Check the type of
the right symbol. Handle $d.
(print_insn): Check for mapping symbols even without a normal
symbol. Adjust searching. If $d is found see how much data
to print. Handle data.
gas/
* config/tc-arm.h (md_cons_align): Define.
(mapping_state): New prototype.
* config/tc-arm.c (mapping_state): Make global.
gas/testsuite/
* gas/arm/arm7t.d, gas/arm/neon-ldst-rm.d, gas/arm/thumb2_pool.d,
gas/arm/tls.d: Update for $d support.
