+Subject: [PATCH] misc: rename copy_file_range to copy_file_chunk
+
+As of 2.27, glibc will have a copy_file_range library call to wrap the
+new copy_file_range system call.  This conflicts with the function in
+misc/create_inode.c, which this patch renames _copy_file_range.

+Subject: [PATCH 40/49] Add ssp_nonshared to link commandline for musl targets
+
+when -fstack-protector options are enabled we need to
+link with ssp_shared on musl since it does not provide
+the __stack_chk_fail_local() so essentially it provides
+libssp but not libssp_nonshared something like
+TARGET_LIBC_PROVIDES_SSP_BUT_NOT_SSP_NONSHARED
+ where-as for glibc the needed symbols
+are already present in libc_nonshared library therefore
+we do not need any library helper on glibc based systems
+but musl needs the libssp_noshared from gcc
+
+Upstream-Status: Pending

+Subject: [PATCH] [ARM] PR 82445 - suppress 32-bit aligned ldrd/strd peepholing
+ with -mno-unaligned-access
+
+Peephole patterns exist in the arm backend to spot load/store
+operations to adjacent memory operations in order to convert them into
+ldrd/strd instructions.  However, when we have strict alignment
+enforced, then we can only do this if the accesses are known to be
+64-bit aligned; this is unlikely to be the case for most loads.  The
+patch adds some alignment checking to the code that validates the
+addresses for use in the peephole patterns.  This should also fix
+incorrect generation of ldrd/strd with unaligned accesses that could
+previously have occurred on ARMv5e where all such operations must be
+64-bit aligned.
+
+I've added some new tests as well.  In doing so I discovered that the
+ldrd/strd peephole tests could never fail since they would match the
+source file name in the scanned assembly as well as any instructions
+of the intended type.  I've fixed those by tightening the scan results
+slightly.
+
+gcc:
+
+* config/arm/arm.c (align_ok_ldrd_strd): New function.
+(mem_ok_for_ldrd_strd): New parameter align.  Extract the alignment of the
+mem into it.
+(gen_operands_ldrd_strd): Validate the alignment of the accesses.
+
+testsuite:
+
+* gcc.target/arm/peep-ldrd-1.c: Tighten test scan pattern.
+* gcc.target/arm/peep-strd-1.c: Likewise.
+* gcc.target/arm/peep-ldrd-2.c: New test.
+* gcc.target/arm/peep-strd-2.c: New test.

+Subject: [PATCH] enable FL_LPAE flag for armv7ve cores
+
+The following commit added the FL_LPAE flag to FL_FOR_ARCH7VE, but
+neglected to also add it to the armv7ve compatible cores defined in
+arm-cores.def.
+
+  https://github.com/gcc-mirror/gcc/commit/af2d9b9e58e8be576c53d94f30c48c68146b0c98
+
+The result is that gcc 6.4 now refuses to allow -march=armv7ve and
+-mcpu=XXX to be used together, even when -mcpu is set to an armv7ve
+compatible core:
+
+  arm-linux-gnueabi-gcc -march=armv7ve -mcpu=cortex-a7 -Werror ...
+  error: switch -mcpu=cortex-a7 conflicts with -march=armv7ve switch [-Werror]
+
+Fix by defining flags for armv7ve compatible cores directly from
+FL_FOR_ARCH7VE, rather than re-creating the armv7ve flags
+independently by combining FL_FOR_ARCH7A with the armv7ve specific
+FL_THUMB_DIV and FL_ARM_DIV flags.

+Subject: [PATCH 03/12] i386: Use const reference of struct ix86_frame to avoid
+ copy
+
+We can use const reference of struct ix86_frame to avoid making a local
+copy of ix86_frame.  ix86_expand_epilogue makes a local copy of struct
+ix86_frame and uses the reg_save_offset field as a local variable.  This
+patch uses a separate local variable for reg_save_offset.
+
+Tested on x86-64 with ada.
+
+	Backport from mainline
+	PR target/83905
+	* config/i386/i386.c (ix86_expand_prologue): Use cost reference
+	of struct ix86_frame.
+	(ix86_expand_epilogue): Likewise.  Add a local variable for
+	the reg_save_offset field in struct ix86_frame.

+Subject: [PATCH 04/12] 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 05/12] 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
+	jmp L1
+L2:
+	lea 8(%rsp), %rsp|lea 4(%esp), %esp
+	ret
+
+and function return becomes
+
+	jmp __x86_return_thunk
+
+-mindirect-branch= tests are updated with -mfunction-return=keep to
+avoid false test failures when -mfunction-return=thunk is added to
+RUNTESTFLAGS for "make check".

+Subject: [PATCH 06/12] 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".

+Subject: [PATCH 11/12] i386: Update -mfunction-return= for return with pop
+
+When -mfunction-return= is used, simple_return_pop_internal should pop
+return address into ECX register, adjust stack by bytes to pop from stack
+and jump to the return thunk via ECX register.
+
+Revision 257992 removed the bool argument from ix86_output_indirect_jmp.
+Update comments to reflect it.
+
+Tested on i686 and x86-64.

+
+x86-64 is supposed to have asynchronous unwind tables by default, but
+there is nothing that reflects the change in the (relative) frame
+address after .LIND0.  That region really has to be moved outside of
+the .cfi_startproc/.cfi_endproc bracket.
+
+This patch adds TARGET_INDIRECT_BRANCH_REGISTER to force indirect
+branch via register whenever -mindirect-branch= is used.  Now,
+-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:
+
+_Z1fP1C:
+.LFB0:
+	.cfi_startproc
+	pushq	%rbx
+	.cfi_def_cfa_offset 16
+	.cfi_offset 3, -16
+	movq	(%rdi), %rax
+	movq	%rdi, %rbx
+	movq	16(%rax), %rax
+	call	__x86_indirect_thunk_rax
+	movq	(%rbx), %rax
+	movq	%rbx, %rdi
+	popq	%rbx
+	.cfi_def_cfa_offset 8
+	movq	16(%rax), %rax
+	jmp	__x86_indirect_thunk_rax
+	.cfi_endproc
+
+so that "-mindirect-branch=thunk-extern" is equivalent to
+"-mindirect-branch=thunk-extern -mindirect-branch-register", which is
+used by Linux kernel.

+
+2017-11-16  Raghunath Lolur  <raghunath.lolur@kpit.com>
+

+	* gcc.target/i386/warn-vect-op-1.c: Likewise
+
+If -Wall, -Werror are used during compilation various test cases fail
+to compile.
+
+If SSE is disabled, be sure to -mfpmath=387 to resolve this.
+
+This patch removes the changes to Changelog from the original patch.
+This will help us avoid conflicts.

+Date: Fri, 19 Jan 2018 17:22:49 +0000
+Subject: [PATCH] gdb: Fix ia64 defining TRAP_HWBKPT before including
+ gdb_wait.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On ia64, gdb_wait.h eventually includes siginfo-consts-arch.h, which
+contains an enum with TRAP_HWBKPT, along with a #define. Thus we cannot
+define TRAP_HWBKPT to 4 beforehand, and so gdb_wait.h must be included
+earlier; include it from linux-ptrace.h so it can never come afterwards.
+
+gdb/ChangeLog:
+
+	* nat/linux-ptrace.c: Remove unnecessary reinclusion of
+	gdb_ptrace.h, and move including gdb_wait.h ...
+	* nat/linux-ptrace.h: ... to here.
+
+Upstream-Status: Accepted [https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h=5a6c3296a7a90694ad4042f6256f3da6d4fa4ee8]

+Subject: [PATCH] memfd: fix configure test
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Recent glibc added memfd_create in sys/mman.h.  This conflicts with
+the definition in util/memfd.c:
+
+    /builddir/build/BUILD/qemu-2.11.0-rc1/util/memfd.c:40:12: error: static declaration of memfd_create follows non-static declaration
+
+Fix the configure test, and remove the sys/memfd.h inclusion since the
+file actually does not exist---it is a typo in the memfd_create(2) man
+page.
