* 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.
|
||||
|
||||
* elf32-hppa.c (elf32_hppa_link_hash_table): Add text_segment_base,
|
||||
and data_segment_base fields.
