Use SEGREL32 relocs for elf32-hppa unwind
- To: binutils at sourceware dot cygnus dot com
- Subject: Use SEGREL32 relocs for elf32-hppa unwind
- From: Alan Modra <alan at linuxcare dot com dot au>
- Date: Sun, 14 Jan 2001 18:00:52 +1100 (EST)
Hi,
This patch changes the reloc used in elf32-hppa .PARISC.unwind sections
from DIR32 to SEGREL32. The segment relative reloc is nicer as the
dynamic linker doesn't need to adjust them.
bfd/ChangeLog
* elf32-hppa.c (elf32_hppa_link_hash_table): Add text_segment_base,
and data_segment_base fields.
(elf32_hppa_link_hash_table_create ): Init them.
(elf32_hppa_check_relocs): Update comments.
(hppa_record_segment_addr): New function.
(elf32_hppa_relocate_section): Call it.
(final_link_relocate): Handle R_PARISC_SEGREL32.
(elf32_hppa_final_link): New function.
(bfd_elf32_bfd_final_link): Define to call it.
(hppa_unwind_entry_compare): New function.
* cache.c (bfd_open_file): Create files in write+read mode.
* elf-hppa.h (elf_hppa_howto_table): Set bitsize value for
SEGREL32 and numerous other relocs. Change duplicate
R_PARISC_NONE relocs to R_PARISC_UNIMPLEMENTED.
gas/ChangeLog
* config/tc-hppa.c (pa_build_unwind_subspace): Use SEGREL32 for
both 32 and 64 bit ELF.
