    • 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.
