This removes the remaining cleanups from coffread.c. Tested by the buildbot and also some manual testing. This version includes the fix provided by Joel. gdb/ChangeLog 2019-03-06 Joel Brobecker <brobecker@adacore.com> Tom Tromey <tom@tromey.com> * stabsread.h (struct stab_section_list): Remove. (coffstab_build_psymtabs): Update. * dbxread.c (symbuf_sections): Now a std::vector. (sect_idx): New global. (fill_symbuf): Update. (coffstab_build_psymtabs): Change type of stabsects parameter. Update. * coffread.c (struct coff_symfile_info) <stabsects>: Now a std::vector. (linetab, linetab_offset, linetab_size, stringtab): Move earlier. (coff_locate_sections): Update. (coff_symfile_read): Remove cleanups. Update. (init_stringtab): Add storage parameter. (free_stringtab, free_stringtab_cleanup): Remove. (init_lineno): Add storage parameter. (free_linetab, free_linetab_cleanup): Remove.
