-mindirect-branch=thunk-extern -O2 on x86-64 GNU/Linux generates:

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.

Make fix for PR 83965 handle SLP reduction chains

This patch prevents pattern-matching of fold-left SLP reduction chains,
which the previous patch for 83965 didn't handle properly.  It only
stops the last statement in the group from being matched, but that's
enough to cause the group to be dissolved later.

A better fix would be to put all the information about the reduction
on the the first statement in the reduction chain, so that every
statement in the group can tell what the group is doing.  That doesn't

[Patch AArch64] Turn on frame pointer / partial fix for PR84521

This fixes a GCC-8 regression that we accidentally switched off frame
pointers in the AArch64 backend when changing the defaults in the common
parts of the code. This breaks an ABI decision that was made in GCC at
the dawn of the port with respect to having a frame pointer at all
times.  If we really want to turn this off lets have a discussion around
that separately.

For now turn this back on and I believe this will leave PR84521 latent
again with -fomit-frame-pointer and (hopefully) make the ruby issue go
away. I'm asking Sudi to pick that up.

Bootstrapped and regression tested on AArch64-none-linux-gnu but I see
one regression in gcc.c-torture/execute/960419-2.c which needs to be
looked at next (PR84528, thanks Kyrill).

Ok to put in and then look at PR84528 ?

nocf_check attribute can be used with -fcf-protection -mcet to disable

When -mindirect-branch=thunk-extern -mindirect-branch-register is added,

Character length cleanup for Coarray Fortran library

Following the change to use size_t for Fortran character lengths (PR
78534), this patch modifies the Coarray ABI in a similar way. The
single-image implementation that is included in libgfortran is
updated, but this needs corresponding work in the OpenCoarray library
as well for multi-image support. I also fixed the types for the STOP
and ERROR STOP implementation in libgfortran, as the calling of them
is somewhat intertwined with the calling of the corresponding CAF
functions. I'll send the OpenCoarray changes as a separate pull
request to the OpenCoarrays repository.

rs6000: Use brace blocks in define_insn

This patch changes the remaining cases in our machine description files
to use brace blocks instead of double-quoted strings as the output
control string.  This increases readability by making the blocks look
more like normal C code, mostly because backslash quoting is no longer
needed.  It also removes such quoting where it was still there (usually
harmless but always confusing). and it writes "\n\t" as "\;" in one
place where we didn't already.
