This changes target_section_table to wrap a std::vector. This simplifies some code, and also enables the simplifications coming in the subsequent patches. Note that for solib, I chose to have it use a pointer to a target_section_table. This is more convoluted than would be ideal, but I didn't want to convert solib to new/delete as a prerequisite for this series. gdb/ChangeLog 2020-10-12 Tom Tromey <tom@tromey.com> * target.c (target_section_by_addr, memory_xfer_partial_1): Update. * target-section.h (struct target_section_table): Use std::vector. * symfile.h (build_section_addr_info_from_section_table): Take a target_section_table. * symfile.c (build_section_addr_info_from_section_table): Take a target_section_table. * solist.h (struct so_list) <sections>: Change type. <sections_end>: Remove. * solib.c (solib_map_sections, clear_so, solib_read_symbols) (solib_contains_address_p): Update. * solib-svr4.c (scan_dyntag): Update. * solib-dsbt.c (scan_dyntag): Update. * remote.c (remote_target::remote_xfer_live_readonly_partial): Update. * record-full.c (record_full_core_start, record_full_core_end): Remove.
