From: Jeff Law Date: Thu, 7 Apr 1994 18:12:25 +0000 (+0000) Subject: * elfcode.h (elf_set_section_contents): Support calling the backend X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=99a6c7613c5c91c5c9b7738b85cc118116afaf65;p=binutils-gdb.git * elfcode.h (elf_set_section_contents): Support calling the backend function elf_backend_begin_write_processing when just beginning to write an object file. * libelf.h (elf_backend_begin_write_processing): Declare. * elf{32,64}-target.h (elf_backend_begin_write_processing): Provide a default definition. (elf{32,64}_bed): Add elf_backend_begin_write_processing. * elf32-hppa.h (elf_hppa_tc_symbol): Delete extern declaration. (elf_hppa_tc_make_sections): Likewise. * elf32-hppa.c (symext_chain_built): Delete. (symext_chain_size): Renamed from symextn_contents_real_size. (elf32_hppa_backend_{begin,final}_write_processing): New functions. (add_entry_to_symext_chain): New function. (hppa_elf_set_section_contents): Ignore writes to the symbol extension section until it's been rebuilt internally. (hppa_elf_get_section_contents): Symbol extension section is no longer special. (elf_backend_{begin,final}_write_processing): Define. (elf_hppa_tc_make_sections): Simplify now that much code has migrated into elf32_hppa_backend_{being,final}_write_processing. --- diff --git a/bfd/ChangeLog b/bfd/ChangeLog index f2f946d7927..085fc8403d9 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,30 @@ +Thu Apr 7 11:10:51 1994 Jeffrey A.
