libgcc/:
	PR libgcc/86213
	* generic-morestack.c (allocate_segment): Move calls to getenv and
	getpagesize to __morestack_load_mmap.
	(__morestack_load_mmap) Initialize static_pagesize and
	use_guard_page here so as to avoid clobbering SSE regs during a
	__morestack call.
gcc/testsuite/:
	* gcc.dg/split-8.c: New.
