From 3e80841e27fd46016d2529eac7eb4f9f7cf1fc05 Mon Sep 17 00:00:00 2001 From: Jeff Law <law@redhat.com> Date: Thu, 11 Nov 1993 23:17:51 +0000 Subject: * elf32-hppa.c (hppa_elf_reloc): Remove DEFUN crud. Remove code which is either commented out or ifdef'd out. Add, update and clean comments. Fix various indention and spacing problems. Handle problems related to using "ble" to jump to a stub rather than "bl" (%r31 is trashed by "ble", but not by "bl"). (NEW_INSTRUCTION): Put inside curly braces. (CURRENT_STUB_OFFSET): Fix indention problems. (hppa_elf_build_arg_reloc_stub): Fix indention and spacing problems. Add, update and clean comments. Handle "ble" %r31 lossage problems. (hppa_elf_build_long_branch_stub): Likewise. (hppa_look_for_stubs_in_section): Likewise. (hppa_elf_stub_check): Remove obsolete function. * hppa_stubs.h: Add new instructions to deal with %r31 lossage problems. Delete unused instructions. --- bfd/ChangeLog | 18 +++++++++++++++++ bfd/hppa_stubs.h | 61 +++++++++++++------------------------------------------- 2 files changed, 32 insertions(+), 47 deletions(-) (limited to 'bfd') diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 120927b..8fb5d56 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,21 @@ +Thu Nov 11 15:16:28 1993 Jeffrey A.
