This is an automated email from the git hooks/post-receive script. unknown user pushed a commit to branch hjl/pr66960/x86 in repository gcc. commit 89073ca538c3c21d840debb6d5a18ff35ce5eccf 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 register is required, 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, to x86 backend. It returns the stack address when the function is called. gcc/ PR target/66960 * config/i386/i386.c (ix86_expand_prologue): Sorry if DRAP is used and the stack address has been taken.

That is to say, some revisions that were in the old version of the branch are not in the new version. This situation occurs when a user --force pushes a change and generates a repository containing something like this: * -- * -- B -- O -- O -- O (2ad19db) \ N -- N -- N refs/heads/hjl/pr66960/generic (f2f00c3) You should already have received notification emails for all of the O revisions, and so the following emails describe only the N revisions from the common base, B. Any revisions marked "omits" are not gone; other references still refer to them. Any revisions marked "discards" are gone forever. The 1 revisions listed above as "new" are entirely new to this repository and will be described in separate emails. The revisions listed as "adds" were already present in the repository and have only been added to this reference.

[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/generic in repository gcc. commit f2f00c36688f3827c602990c17ee23da6a974deb 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 register is required, 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.
