[gcc] 01/01: Add __builtin_stack_top

by git

This is an automated email from the git hooks/post-receive script. unknown user pushed a commit to branch hjl/pr66960 in repository gcc. commit 53c2dd6e303d48eccf050696020b3765d3c4c382 Author: H.J. Lu <hjl.tools(a)gmail.com> Date: Tue Jul 21 14:32:09 2015 -0700 Add __builtin_stack_top When __builtin_frame_address is used to retrieve the address of the function stack frame, the frame pointer is always kept, which wastes one register and 2 instructions. For x86-32, one less register means significant negative impact on performance. This patch adds a new builtin function, __builtin_stack_top. It returns the stack address when the function is called. This patch only enables __builtin_stack_top for x86 backend. Using __builtin_stack_top with other backends will lead to sorry, unimplemented: ‘__builtin_stack_top’ not supported on this target TARGET_STACK_TOP_RTX must be defined to enable __builtin_stack_top. default_stack_top_rtx may be extended to support more backends, including those with INITIAL_FRAME_ADDRESS_RTX. gcc/ PR target/66960 * builtin-types.def (BT_FN_PTR_VOID): New function type. * builtins.c (expand_builtin): Handle BUILT_IN_STACK_TOP.
