I have renamed ix86_split_stack_boundary to ix86_split_stack_guard
(and added missing function comment), so the new ChangeLog reads:
2017-08-10 Uros Bizjak <ubizjak@gmail.com>
* config/i386/i386-protos.h (ix86_split_stack_guard): New prototype.
* config/i386/i386.c (ix86_split_stack_guard): New function.
(ix86_xpand_split_stack_prologue): Call ix86_split_stack_guard.
(ix86_legitimate_address_p) <case UNSPEC_STACK_CHECK>: Remove.
(i386_asm_output_addr_const_extra) <case UNSPEC_STACK_CHECK>: Ditto.
(optput_pic_addr_const): Remove UNSPEC_STACK_CHECK handling.
* config/i386/i386.md (unspec): Remove UNSPEC_STACK_CHECK.
(split_stack_space_check): Call ix86_split_stack_guard.
Uros.
