Alexandre Oliva 5153284539 2003-12-17 Alexandre Oliva <aoliva@redhat.com>
* elf32-frv.c (_frv_osec_readonly_p): New.

undefweak symbol.
(_frv_count_got_plt_entries): Adjust expected count accordingly.
(elf32_frv_relocate_section): Likewise.  Error out if attempting
to emit rofixups or dynamic relocs in read-only segments.  Use
_bfd_elf_section_offset to adjust r_offsets in rofixups and
dynamic relocations.
2003-12-12  Alexandre Oliva  <aoliva@redhat.com>
* elf32-frv.c (elf32_frv_relocate_section): Compute dynamic
relocations or fixups involving merged sections correctly.  Avoid
crash when undefined symbol is referenced by R_FRV_32 or
R_FRV_FUNCDESC_VALUE.
2003-12-02  Alexandre Oliva  <aoliva@redhat.com>
* elf32-frv.c (elf32_frv_relocate_section): Add output_offset of
input section holding local symbol to addend of R_FRV_32 or
R_FRV_FUNCDESC_VALUE dynamic relocation.

of the lazy PLT entry, not only its offset, as the low word of a
function descriptor.
2003-11-10  Alexandre Oliva  <aoliva@redhat.com>

(_frv_emit_got_relocs_plt_entries): Use NULL as funcdesc address
for undefweak symbols.
(elf32_frv_relocate_section): Avoid crash while computing
relocation when linking with shared library.  Only emit rofixups
and dynamic relocations for alloc&load sections.  Mark binaries
with inter-segment relocations for relocation as a unit.
(_frv_create_got_section): Rename .rofixup.got to .rofixup.
(DEFAULT_STACK_SIZE): New.

shared libraries.  Emit rofixup for R_FRV_32 only if input object
is not FDPIC.
(_frv_create_got_section): Define _gp symbol in the rofixup
section.
(elf32_frv_finish_dynamic_sections): If rofixups needed but
dynamic sections missing, error out requesting -melf32frvfd.
2003-09-19  Alexandre Oliva  <aoliva@redhat.com>
* elf32-frv.c (_frv_emit_got_relocs_plt_entries): Rearrange
computation of addends from section and global or local symbol
value.  Change return type to bfd_boolean, and return a failure if
a dynamic FUNCDESC or FUNCDESC_VALUE relocation that requires a
nonzero addend is required.

unsupported nonzero addends.

relocations in fdpic.
(_frv_create_got_section): Create .rofixup.got section.
(struct _frv_dynamic_got_info): Added fixups.
(_frv_count_got_plt_entries): Account in-GOT relocations into

argument, so as to not call _bfd_elf_rel_local_sym to compute it.
(elf32_frv_relocate_section): Pass relocation addend in.  Use
original relocation addend to look up the got relocs/plt entries
table.  Do not call _bfd_elf_rel_local_sym.  Don't error out when
processing relocations that reference .scommon symbols.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
