This patch should fix the nastiest configuration bugs for no_cpu/no_bsp.
With this patch applied, configure --target=no_cpu-rtems now correctly
acknowledges its configuration, but later fails building when trying to
build libcsupport (I leave this problem for you :-).
Fixes/Changes:
* aclocal/canonicalize-target-name.m4: use RTEMS_CPU instead of
target_cpu, switch to a native compiler setup if target = no_cpu*rtems,
ie. implicitly use host=target (native) and RTEMS_CPU=no_cpu for
--target=no_cpu*rtems.
* add no_bsp/bsp_specs (Support -qrtems, -qrtems_debug; please check
before adding :-)
* Use RTEMS_CANONICALIZE_TARGET_CPU instead of AC_CANONICAL_SYSTEM in
toplevel/configure.in
* All references to $target_cpu in aclocal/*.m4, Makefile.ins and *.cfg
files changed to RTEMS_CPU
* bug fixes to exec/score/cpu/no_cpu/wrap (This part of the patch may
result into patch rejections, because your recently posted patch may
also have addressed this problem).
After applying this patch, please do:
cvs add c/src/lib/libbsp/no_cpu/no_bsp/bsp_specs
