    • i386: Add __x86_indirect_thunk_nt_reg for -fcf-protection -mcet · 73b8b822 
      nocf_check attribute can be used with -fcf-protection -mcet to disable
control-flow check by adding NOTRACK prefix before indirect branch.
When -mindirect-branch=thunk-extern -mindirect-branch-register is added,
indirect branch via register, "notrack call/jmp reg", is converted to

    call/jmp __x86_indirect_thunk_nt_reg

When running on machines with CET enabled, __x86_indirect_thunk_nt_reg
can be updated to

    notrack jmp reg

at run-time to restore NOTRACK prefix in the original indirect branch.

Since we don't support -mindirect-branch=thunk-extern, CET and MPX at
the same time, -mindirect-branch=thunk-extern is disallowed with
-fcf-protection=branch and -fcheck-pointer-bounds.

Tested on i686 and x86-64.

    • [ARM] Multilib mapping for Armv8-R · 9029d342 
      Due to there being no multilib mapping for Armv8-R, default multilib
builts for -march=armv4t with softfloat floating-point arithmetic is
being used. This patch maps it instead to the existing Armv7 multilibs.
Note that mapping for single-precision Armv8-R has been left out due to
there being no Arm implementation of that architecture variant.

    • Character length cleanup for Coarray Fortran library · 3f5fabc0 
      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.

      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.
