From 6590a8c953ac7537b79cde4e6ed9d825721fedeb Mon Sep 17 00:00:00 2001 From: Steve Chamberlain Date: Tue, 28 Jan 1992 06:01:25 +0000 Subject: [PATCH] New entry point in the transfer vector - bfd_relax_section. * aout-target.h: add to vector, call generic_relax * bfd-in.h: add to vector * bfd.c: add #define for vector * bout.c: add to vector, call generic_relax * coffcode.h: add to vector, also now has coff specific relax code for the relaxable H8/300 relocs. Also clean up abs section cruft. * elf.c: call generic_relax * ieee.c: call new vector, clean up some bugs due to the creation of bfd_abs_section * libbfd.h: add bfd_generic_relax_section EXFUN * oasys.c: call generic_relax * reloc.c: implement generic_relax * seclet.c: moved much of this into coffcode.h * srec.c: call generic_relax * targets.c: define new transfer vector --- bfd/ChangeLog | 22 +++ bfd/bfd.c | 4 + bfd/coffcode.h | 492 +++++++++++++++++++++++++++++++++++++++++++++++++++++---- bfd/seclet.c | 241 ---------------------------- 4 files changed, 485 insertions(+), 274 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index 2f73749..f53aa5e 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,25 @@ +Mon Jan 27 19:44:08 1992 Steve Chamberlain (sac at rtl.cygnus.com) + + New entry point in the transfer vector - bfd_relax_section. + + * aout-target.h: add to vector, call generic_relax + * bfd-in.h: add to vector + * bfd.c: add #define for vector + * bout.c: add to vector, call generic_relax + * coffcode.h: add to vector, also now has coff specific relax code + for the relaxable H8/300 relocs.
