(uintptr_type): Define. (struct initial_sp): Add dont_block_signals field. Reduce size of extra array by 1. (allocate_segment): Set prev field to NULL. Don't set __morestack_current_segment or __morestack_segments. (__generic_morestack): Update current->prev and *pp after calling allocate_segment. (__morestack_block_signals): Don't do anything if dont_block_signals is set. (__morestack_unblock_signals): Likewise. (__generic_findstack): Check for initial_sp == NULL. Add casts to uintptr_type. (__splitstack_block_signals): New function. (enum __splitstack_content_offsets): Define. (__splitstack_getcontext, __splitstack_setcontext): New functions. (__splitstack_makecontext): New function. (__splitstack_block_signals_context): New function. (__splitstack_find_context): New function. * config/i386/morestack.S (__morestack_get_guard): New function. (__morestack_set_guard, __morestack_make_guard): New functions. * libgcc-std.ver.in: Add new functions to GCC_4.7.0. gcc/testsuite/: * lib/target-supports.exp (check_effective_target_ucontext_h): New procedure. * gcc.dg/split-5.c: New test.
