Alan Modra 499766a6d7 Re: The problem with warning in elf_object_p
Commit 5aa0f10c42 added a per_xvec_warn array to provide support for
warnings from elf_object_p (and a later patch for warnings from
pe_bfd_object_p) to be cached and then only printed if the target
matches.  It was quite limited in the style of message supported, only
one message could be printed, and didn't really meet the stated aim of
only warning when a target matches:  There are many other errors and
warnings that can be emitted by functions called from elf_object_p.

So this patch extends the error handler functions to support printing
to a string buffer, extends per_xvec_warn to support multiple errors/
warnings, and hooks this all into bfd_check_format_matches.  If
bfd_check_format_matches succeeds then any errors/warnings are printed
for the matching target.  If bfd_check_format_matches fails either due
to no match or to multiple matches and only one target vector produced
errors, then those errors are printed.

	* bfd.c (MAX_ARGS): Define, use throughout.
	(print_func): New typedef.
	(_bfd_doprnt): Add new print param.  Replace calls to fprintf
	with print.
	(PRINT_TYPE): Similarly.
	(error_handler_fprintf): Renamed from error_handler_internal.
	Use _bfd_get_error_program_name.  Add fprintf arg.  Move code
	setting up args..
	(_bfd_doprnt_scan): ..to here.  Add ap param.
	(struct buf_stream): New.
	(err_sprintf): New function.
	(error_handler_bfd): New static variable.
	(error_handler_sprintf): New function.
	(_bfd_set_error_handler_caching): New function.
	(_bfd_get_error_program_name): New function.
	* elfcode.h (elf_swap_shdr_in): Use _bfd_error_handler in
	warning messages.
	(elf_object_p): Likewise.
	* format.c (print_warnmsg): New function.
	(clear_warnmsg): Rewrite.
	(null_error_handler): New function.
	(bfd_check_format_matches): Ignore warnings from recursive calls
	checking first element of an archive.  Use caching error handler
	otherwise.  Print warnings on successful match, or when only one
	target has emitted warnings/errors.
	* peicode.h (pe_bfd_object_p): Use _bfd_error_handler in
	warning messages.
	* targets.c (per_xvec_warn): Change type of array elements.
	(struct per_xvec_message): New.
	(_bfd_per_xvec_warn): Rewrite.
	* Makefile.am (LIBBFD_H_FILES): Add bfd.c.
	* Makefile.in: Regenerate.
	* bfd-in2.h: Regenerate.
	* libbfd.h: Regenerate.

		   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.
