From 4a378b13e498c735d6f51c546466d4d6a06da74c Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Thu, 9 Nov 1995 19:44:09 +0000 Subject: * coffcode.h (coff_set_alignment_hook): Write RS6000COFF_C version which checks for STYP_OVRFLO sections. (coff_compute_section_file_positions): If RS6000COFF_C, handle reloc and lineno count overflows. (coff_write_object_contents): Call coff_count_linenumbers before coff_compute_section_file_positions. If RS6000COFF_C, handle reloc and lineno count overflows. * xcofflink.c (_bfd_xcoff_bfd_final_link): Count line numbers and relocs before dealing with .pad sections. Count overflow section headers when handling .pad sections. --- bfd/ChangeLog | 11 +++++ bfd/xcofflink.c | 133 +++++++++++++++++++++++++++++--------------------------- 2 files changed, 80 insertions(+), 64 deletions(-) (limited to 'bfd') diff --git a/bfd/ChangeLog b/bfd/ChangeLog index f3ad724..47e3865 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,5 +1,16 @@ Thu Nov 9 13:01:31 1995 Ian Lance Taylor + * coffcode.h (coff_set_alignment_hook): Write RS6000COFF_C version + which checks for STYP_OVRFLO sections. + (coff_compute_section_file_positions): If RS6000COFF_C, handle + reloc and lineno count overflows. + (coff_write_object_contents): Call coff_count_linenumbers before + coff_compute_section_file_positions.
