Options

configure.in: Set with_gnu_as, with_gnu_ld, with_newlib earlier. 

2006-01-26  Paolo Bonzini  <bonzini@gnu.org>

	* configure.in: Set with_gnu_as, with_gnu_ld, with_newlib earlier.
	Set md_exec_prefix.  Use ACX_CHECK_INSTALLED_TARGET_TOOL to find
	the assembler, linker and binutils.
	* configure: Regenerate.

2006-01-26  Paolo Bonzini  <bonzini@gnu.org>

	* config/acx.m4 (NCN_STRICT_CHECK_TARGET_TOOLS): Test
	$with_build_time_tools.
	(ACX_PATH_SEP): New.
	(ACX_TOOL_DIRS): Move here from the gcc directory.
	(ACX_CHECK_INSTALLED_TARGET_TOOL): New.
	(GCC_TARGET_TOOL): Do not use a host tool if we found a target tool
	with a complete path in either $with_build_time_tools or $exec_prefix.

2006-01-26  Paolo Bonzini  <bonzini@gnu.org>

	* configure.ac: Expect target tools paths to be passed from the toplevel
	and wrap the detection into AS_SET_VAR_IF.  Extract side-effects out of
	AS_SET_VAR_IF.
	* acinclude.m4 (gcc_AC_TOOL_DIRS, gcc_AC_CHECK_TOOL): Remove.

# Searching for installed target binutils. We need to take extra care,
# else we may find the wrong assembler, linker, etc., and lose.
#
# First try --with-build-time-tools, if specified.
#
# For build != host, we ask the installed GCC for the name of the tool it
# uses, and accept it if it is an absolute path. This is because the
# only good choice for a compiler is the same GCC version that is being
# installed (or we couldn't make target libraries), and we assume that
# on the host system we'll have not only the same GCC version, but also
# the same binutils version.
#
# For build == host, search the same directories that the installed
# compiler will search. We used to do this for the assembler, linker,
# and nm only; for simplicity of configuration, however, we extend this
# criterion to tools (such as ar and ranlib) that are never invoked by
# the compiler, to avoid mismatches.
#
# Also note we have to check MD_EXEC_PREFIX before checking the user's path
# if build == target. This makes the most sense only when bootstrapping,
# but we also do so when build != host. In this case, we hope that the
# build and host systems will have similar contents of MD_EXEC_PREFIX.
#
# If we do not find a suitable binary, then try the user's path.
