From: Ian Lance Taylor Date: Mon, 17 Jul 1995 17:33:37 +0000 (+0000) Subject: * stabsread.h (struct stab_section_list): Define. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f779e99f2ab25060486dc11ab2fcddba0cacf918;p=binutils-gdb.git * stabsread.h (struct stab_section_list): Define. (coffstab_build_psymtabs): Remove staboff and stabsize parameters. Add textaddr, textsize, and stabs parameters. * gdb-stabs.h (struct dbx_symfile_info): Remove text_sect field. Add text_addr and text_size fields. (DBX_TEXT_SECT): Don't define. (DBX_TEXT_ADDR, DBX_TEXT_SIZE): Define. * coffread.c: Include . (struct coff_symfile_info): Remove stabsect and stabindexsect fields. Add textaddr, textsize, and stabsects fields. (coff_locate_sections): Record the address of the .text section, and total the sizes of all sections with names beginning with ".text". Don't bother to record a .stab.index section (COFF doesn't use them). Make a linked list of all sections with names beginning with ".stab". (coff_symfile_read): Adjust call to coffstab_build_psymtabs for new parameters. * dbxread.c (dbx_symfile_read): Use DBX_TEXT_ADDR and DBX_TEXT_SIZE, rather than getting both from DBX_TEXT_SECT. (dbx_symfile_init): Set DBX_TEXT_ADDR and DBX_TEXT_SIZE, not DBX_TEXT_SECT. (elfstab_build_psymtabs): Likewise. (stabsect_build_psymtabs): Likewise. (symbuf_sections, symbuf_left, symbuf_read): New static variables. (fill_symbuf): If symbuf_sections is not NULL, read symbols from multiple sections. (coffstab_build_psymtabs): Remove staboffset and stabsize parameters. Add textaddr, textsize, and stabsects parameters. Set DBX_TEXT_ADDR and DBX_TEXT_SIZE, not DBX_TEXT_SECT. Handle multiple stabs sections. * os9kread.c (os9k_symfile_read): Use DBX_TEXT_ADDR and DBX_TEXT_SIZE, rather than getting both from DBX_TEXT_SECT. (os9k_symfile_init): Set DBX_TEXT_ADDR and DBX_TEXT_SIZE, not DBX_TEXT_SECT.
