+Subject: [PATCH] Fix bti support (#830)
+
+* bti: add identifier to ffi_closure_SYSV_V_alt
+
+This was missing BTI_C identifier.
+
+Old Code:
+ffi_closure_SYSV_V_alt:
+0000fffff7f70500: ldr x17, [sp, #8]
+
+Signed-off-by: Bill Roberts <bill.roberts@arm.com>
+
+* testsuite: fix whitespace in Makefile.am
+
+Signed-off-by: Bill Roberts <bill.roberts@arm.com>
+
+* aarch64: correct comment describing BTI
+
+The comment is incorrect, BTI is enabled per mapping via mprotect with
+PROT_BTI flag set, not per-process. When the loader loads the library,
+if the GNU Notes section is missing this, PROT_BTI will not be enabled
+for that mapping, but is independent of other mappings.

+
+This is a fix for https://github.com/libffi/libffi/issues/852: error: invalid CFI advance_loc expression on apple targets.
+
+The CFI for darwin arm64 was broken because the CNAME macro was being used after the
+cfi_startproc macro.

+Subject: [PATCH] aarch64: support pointer authentication (#834)
+
+* aarch64: fix callstack in ffi_call_SYSV
+
+The debug stack gets corrupted between the frame and stack pivots, update
+the CFI directives so the call stack stays correct in the debugger.
+
+str x9, [x1, #32] // stack is ffi_call_SYSV() -> ffi_call_int() -> ffi_call_int() -> main() (good)
+mov x29, x1 // stack is ffi_call_SYSV() -> ffi_call_int() -> ffi_call_int() -> ffi_call() -> main() (bad)
+mov sp, x0 // stack is ffi_call_SYSV() -> ffi_call_int() -> ffi_call_int() -> main() (good)
+
+The CFA data needs to be updated around the pivots, after this patch the
+callstack stays correct.
+
+Signed-off-by: Bill Roberts <bill.roberts@arm.com>
+
+* aarch64: remove uneeded CFI directive
+
+This directive doesn't actually set the CFA to anything valid, and
+during unwinding this isn't even used. Note that the PAC/Darwin usage
+is quite suspect as well, as the CFA is either x1 or x29 after the frame
+pivot, and the CFA address is what's used as the modifier when verifying
+the PAC. At least this is the behavior on Linux with PAC, I need to
+verify ARME ABI unwinding. So for now leave Darwin as is.
+
+Signed-off-by: Bill Roberts <bill.roberts@arm.com>
+
+* ptrauth: rename define for clarity
+
+Rename the HAVE_PTRAUTH define for clarity that its associated with the
+ARM64E ABI and not the ARM64 ABI that can be supported on Linux and
+enabled with -mbranch-protection=standard.
+
+Signed-off-by: Bill Roberts <bill.roberts@arm.com>
+
+* aarch64: add PAC support to ffi_call_SYSV
+
+Support AARCH64 Pointer Authentication Codes (PAC) within ffi_call_SYSV
+and support exception unwinding.
+
+The Linux ABI for PAC is to use paciasp/autiasp instructions which also
+have hint space equivelent instructions. They sign the LR (x30) with the
+A key and the current stack pointer as the salt. Note that this can also be
+configured to use the B key and will use pacibsp/autibsp hint instructions.
+
+The Linux ABI for exception frame data when PAC is enabled assumes that the
+Connonical Frame Address, or CFA is equal to the stack pointer. I.E sp is
+equal to x29 (fp). When the unwinder is invoked the cfa will point to
+the frame which will include the *signed* return address from the LR.
+This will then be passed to __builtin_aarch64_autia1716 where the CFA
+will be used as the salt and stored to register x16 and register x17
+will contain the signed address to demangle. This can be noted in:
+ - https://github.com/gcc-mirror/gcc/blob/d6d7afcdbc04adb0ec42a44b2d7e05600945af42/libgcc/config/aarch64/aarch64-unwind.h#L56
+
+The other required portion of this is to indicate to the unwinder that
+this is a signed address that needs to go the special demangle route in
+the unwinder. This is accomplished by using CFI directive "cfi_window_save"
+which marks that frame as being signed.
+
+Putting all of this together is a bit tricky, as the internals of
+ffi_call_SYSV the callee allocates its stack and frame and passes it in
+arg1 (x0) and arg2 (x1) to the called function, where that function
+pivots its stack, so care must be taken to get the sp == fp before
+paciasp is called and also restore that state before autiasp is called.

+Subject: [PATCH] Disable ASAN in ffi_call_int functions (#858)
+
+The pattern for several of the architectures is for ffi_call_int to
+stack-allocate some arguments + the registers, and then
+ffi_call_$ARCH will pop the top of that structure into registers, and
+then adjust the stack pointer such that the alloca'd buffer _becomes_
+the stack-passed arguments for the function being called.
+
+If libffi is compiled with ASAN, then there will be a redzone inserted
+after the alloca'd buffer which is marked as poisoned. This redzone
+appears beyond the end of $sp upon entry to the called function.
+
+If the called function does anything to use this stack memory, ASAN will
+notice that it's poisoned and report an error.
+
+This commit fixes the situation (on the architectures that I have access
+to) disabling instrumentation for ffi_call_int; that means there will be
+no alloca redzone left on the shadow-stack.
