-From: "H.J. Lu" <hjl.tools@gmail.com>
-To: gcc-patches@gcc.gnu.org
-Subject: [1/3] GCC 7: i386: Move struct ix86_frame to machine_function
-Date: Sun, 14 Jan 2018 07:02:35 -0800
-
-Make ix86_frame available to i386 code generation.  This is needed to
-backport the patch set of -mindirect-branch= to mitigate variant #2 of
-the speculative execution vulnerabilities on x86 processors identified
-by CVE-2017-5715, aka Spectre.
-
-	Backport from mainline
-	* config/i386/i386.c (ix86_frame): Moved to ...
-	* config/i386/i386.h (ix86_frame): Here.
-	(machine_function): Add frame.
-	* config/i386/i386.c (ix86_compute_frame_layout): Repace the
-	frame argument with &cfun->machine->frame.
-	(ix86_can_use_return_insn_p): Don't pass &frame to
-	ix86_compute_frame_layout.  Copy frame from cfun->machine->frame.
-	(ix86_can_eliminate): Likewise.
-	(ix86_expand_prologue): Likewise.
-	(ix86_expand_epilogue): Likewise.
-	(ix86_expand_split_stack_prologue): Likewise.

-Subject: [2/3] GCC 7: i386: Use reference of struct ix86_frame to avoid copy
-Date: Sun, 14 Jan 2018 07:02:36 -0800
-
-When there is no need to make a copy of ix86_frame, we can use reference
-of struct ix86_frame to avoid copy.
-
-Tested on x86-64.
-
-	Backport from mainline
-	* config/i386/i386.c (ix86_can_use_return_insn_p): Use reference
-	of struct ix86_frame.
-	(ix86_initial_elimination_offset): Likewise.
-	(ix86_expand_split_stack_prologue): Likewise.

-Subject: [PATCH] x86: Add -mindirect-branch=
-
-Add -mindirect-branch= option to convert indirect call and jump to call
-and return thunks.  The default is 'keep', which keeps indirect call and
-jump unmodified.  'thunk' converts indirect call and jump to call and
-return thunk.  'thunk-inline' converts indirect call and jump to inlined
-call and return thunk.  'thunk-extern' converts indirect call and jump to
-external call and return thunk provided in a separate object file.  You
-can control this behavior for a specific function by using the function
-attribute indirect_branch.
-
-2 kinds of thunks are geneated.  Memory thunk where the function address
-is at the top of the stack:
-
-__x86_indirect_thunk:
-	call L2
-L1:
-	pause
-	lfence
-	jmp L1
-L2:
-	lea 8(%rsp), %rsp|lea 4(%esp), %esp
-	ret
-
-Indirect jmp via memory, "jmp mem", is converted to
-
-	push memory
-	jmp __x86_indirect_thunk
-
-Indirect call via memory, "call mem", is converted to
-
-	jmp L2
-L1:
-	push [mem]
-	jmp __x86_indirect_thunk
-L2:
-	call L1
-
-Register thunk where the function address is in a register, reg:
-
-__x86_indirect_thunk_reg:
-	call	L2
-L1:
-	pause
-	lfence
-	jmp	L1
-L2:
-	movq	%reg, (%rsp)|movl    %reg, (%esp)
-	ret
-
-where reg is one of (r|e)ax, (r|e)dx, (r|e)cx, (r|e)bx, (r|e)si, (r|e)di,
-(r|e)bp, r8, r9, r10, r11, r12, r13, r14 and r15.

-Subject: [PATCH] x86: Add -mfunction-return=
-
-Add -mfunction-return= option to convert function return to call and
-return thunks.  The default is 'keep', which keeps function return
-unmodified.  'thunk' converts function return to call and return thunk.
-'thunk-inline' converts function return to inlined call and return thunk.
-'thunk-extern' converts function return to external call and return
-thunk provided in a separate object file.  You can control this behavior
-for a specific function by using the function attribute function_return.
-
-Function return thunk is the same as memory thunk for -mindirect-branch=
-where the return address is at the top of the stack:
-
-__x86_return_thunk:
-	call L2
-L1:
-	pause
-	lfence

-i386: Don't use ASM_OUTPUT_DEF for TARGET_MACHO
-
-ASM_OUTPUT_DEF isn't defined for TARGET_MACHO.  Use ASM_OUTPUT_LABEL to
-generate the __x86_return_thunk label, instead of the set directive.
-Update testcase to remove the __x86_return_thunk label check.  Since
--fno-pic is ignored on Darwin, update testcases to sscan or "push"
-only on Linux.

-Subject: [PATCH] x86: Add -mindirect-branch-register
-
-Add -mindirect-branch-register to force indirect branch via register.
-This is implemented by disabling patterns of indirect branch via memory,
-similar to TARGET_X32.
-
--mindirect-branch= and -mfunction-return= tests are updated with
--mno-indirect-branch-register to avoid false test failures when
--mindirect-branch-register is added to RUNTESTFLAGS for "make check".
