From b26059aa449b61de921a90e76e8efcd75dd772a6 Mon Sep 17 00:00:00 2001 From: Ian Lance Taylor Date: Fri, 23 Oct 1992 15:28:15 +0000 Subject: [PATCH] Fri Oct 23 08:15:56 1992 Ian Lance Taylor (ian@cygnus.com) * changes to support i386-sysv with shared libraries: * coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined, check for .data2; if _LIB is defined, check for it; map SEC_NEVER_LOAD to STYP_NOLOAD. (styp_to_sec_flags): map STYP_NOLOAD to SEC_NEVER_LOAD. (make_a_section_from_file): if TWO_DATA_SECS, accept .data2. (coff_write_object_contents): force vaddr of .lib to 0; set scnptr if section has contents, not just if it is loadable; if TWO_DATA_SECS, check for .data2 (coff_set_section_contents): set vma of .lib section to number of .lib sections. * coff-i386.c: define TWO_DATA_SECS; use a special CALC_ADDEND; don't define coff_write_armap to bsd_write_armap. * hosts/i386v.h: don't include , since it is not provided by SVR3.2. --- bfd/ChangeLog | 27 +++++++++++++++++++++ bfd/coffcode.h | 61 +++++++++++++++++++++++++++++++++++++++++------ bfd/hosts/i386v.h | 1 - 3 files changed, 81 insertions(+), 8 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 820a64b7eba..8f08a881816 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,30 @@ +Fri Oct 23 08:15:56 1992 Ian Lance Taylor (ian@cygnus.com) + + * changes to support i386-sysv with shared libraries: + * coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined, + check for .data2; if _LIB is defined, check for it; map + SEC_NEVER_LOAD to STYP_NOLOAD. + (styp_to_sec_flags): map STYP_NOLOAD to SEC_NEVER_LOAD. + (make_a_section_from_file): if TWO_DATA_SECS, accept .data2. + (coff_write_object_contents): force vaddr of .lib to 0; set scnptr + if section has contents, not just if it is loadable; if + TWO_DATA_SECS, check for .data2 + (coff_set_section_contents): set vma of .lib section to number of + .lib sections. + * coff-i386.c: define TWO_DATA_SECS; use a special CALC_ADDEND; + don't define coff_write_armap to bsd_write_armap. + * hosts/i386v.h: don't include , since it is not provided + by SVR3.2. + +Thu Oct 22 22:40:20 1992 Brendan Kehoe (brendan@lisa.cygnus.com) + + * solaris2.h: Get the definition of alloca from alloca.h if we + aren't using gcc. + +Thu Oct 22 03:07:28 1992 John Gilmore (gnu@cygnus.com) + + * configure.in (i960-*-{aout,bout}): Support these. + Wed Oct 21 03:46:34 1992 John Gilmore (gnu@cygnus.com) * config/a29k-aout.mt (DEFAULT_TARGET): Set to one that exists. diff --git a/bfd/coffcode.h b/bfd/coffcode.h index 1fef14854b5..af9cef65e12 100644 --- a/bfd/coffcode.h +++ b/bfd/coffcode.h @@ -1,5 +1,5 @@ /* Support for the generic parts of most COFF variants, for BFD. - Copyright (C) 1990-1991 Free Software Foundation, Inc. + Copyright 1990, 1991, 1992 Free Software Foundation, Inc.
