Thanks, I installed that patch, as well as the patch for microblazeel.

Thanks. Going a step further, I searched for all "#define STACK_GROWS_DOWNWARD 1"
in the GCC 11 sources, and added the info for these embedded CPUs as well
(translating the CPU names in the same way as config.sub does).


2021-12-05  Bruno Haible  <bruno@clisp.org>

	sigsegv: Fix build on some more embedded CPUs.
	* m4/stack-direction.m4 (SV_STACK_DIRECTION): Assume the stack grows
	negative, when the GCC 11 sources say so.
