Linux target variants for elfxx-hppa
- To: binutils at sourceware dot cygnus dot com
- Subject: Linux target variants for elfxx-hppa
- From: Alan Modra <alan at linuxcare dot com dot au>
- Date: Sun, 14 Jan 2001 22:08:19 +1100 (EST)
Hi,
These patches add elf{32,64}-hppa-linux bfd targets since the existing
targets set OSABI to ELFOSABI_HPUX, which is wrong for Linux.
bfd/ChangeLog
* config.bfd: Add linux target variant for elfxx-hppa.
* configure.in: Recognize bfd_elf32_hppa_linux_vec and
bfd_elf64_hppa_linux_vec.
* configure: Regenerate.
* elf64-hppa.c: Include elf64-target.h again to support linux
target variant.
(elf64_hppa_post_process_headers): Set ELFOSABI_LINUX for linux.
* elf32-hppa.c: Include elf32-target.h again to support linux
target variant.
(elf32_hppa_post_process_headers): New function.
(elf_backend_post_process_headers): Define.
* targets.c (bfd_target_vector): Add bfd_elf64_hppa_linux_vec and
bfd_elf32_hppa_linux_vec.
gas/ChangeLog
* config/tc-hppa.h (TARGET_FORMAT): Add hppa-linux variants.
ld/ChangeLog
* emulparams/hppalinux.sh (OUTPUT_FORMAT): Set to elf32-hppa-linux.
