Note, the above is not the right ChangeLog formatting when you have more
than one author.  The date should be there only for the first line, for the
other authors there should be just tab and 4 spaces, otherwise various tools
that parse ChangeLog entries will be quite confused.  So like:
2019-12-18  Mihail Ionescu  <mihail.ionescu@arm.com>
	    Andre Vieira  <andre.simoesdiasvieira@arm.com>

I've fixed your commits in 2b3534a3122236d6317256f16daa332278391907
but please remember this next time.

Thanks.

	Jakub

Thank you, I did not realise that I wasn't using the correct formatting 
style. I'll keep that in mind for next time.

Two more things.

One is I wonder if it has been bootstrapped, because at least in a cross
from x86_64-linux to armv7hl-linux-gnueabi I'm seeing:
../../gcc/config/arm/arm.c: In function ‘void cmse_nonsecure_call_inline_register_clear()’:
../../gcc/config/arm/arm.c:18469:18: warning: unused variable ‘next’ [-Wunused-variable]
        rtx_insn *next, *last, *pop_insn, *after = insn;
                  ^~~~
warning, which I believe in bootstrap would result in
-Werror=unused-variable error.
The variable is really unused, so I've checked in as obvious following
patch.

The other thing is that https://gcc.gnu.org/codingconventions.html and
https://www.gnu.org/prep/standards/standards.html#Formatting say that 
	rtx tmp =
	  copy_to_suggested_reg (XEXP (operands[0], 0),
				 gen_rtx_REG (SImode, R4_REGNUM),
				 SImode);
etc. I've seen in your patch is not correctly formatted, the =
should not be at the end of line (similarly to |, &, ||, &&, +, -,
etc.), but should be at the start of the next line.
That would be then
	rtx tmp
	  = copy_to_suggested_reg (XEXP (operands[0], 0),
				   gen_rtx_REG (SImode, R4_REGNUM),
				   SImode);
but the line is really short, so I don't see a point to break line there at
all, you can just use:
	rtx tmp = copy_to_suggested_reg (XEXP (operands[0], 0),
					 gen_rtx_REG (SImode, R4_REGNUM),
					 SImode);

Bootstrap found yet another unused variable:
../../gcc/config/arm/vfp.md:1651:17: warning: unused variable 'regname' [-Wunused-variable]

Fixed thusly, committed as obvious to trunk.

[-- Attachment #1: Type: text/plain, Size: 6866 bytes --]

Hi,

This patch adds CLI and multilib support for Armv8.1-M MVE to the Arm backend.
Two new option added for v8.1-m.main: "+mve" for integer MVE instructions only
and "+mve.fp" for both integer and single-precision/half-precision
floating-point MVE.
The patch also maps the Armv8.1-M multilib variants to the corresponding v8-M ones.



gcc/ChangeLog:

2019-11-08  Mihail Ionescu  <mihail.ionescu@arm.com>
2019-11-08  Andre Vieira  <andre.simoesdiasvieira@arm.com>

	* config/arm/arm-cpus.in (mve, mve_float): New features.
	(dsp, mve, mve.fp): New options.
	* config/arm/arm.h (TARGET_HAVE_MVE, TARGET_HAVE_MVE_FLOAT): Define.
	* config/arm/t-rmprofile: Map v8.1-M multilibs to v8-M.


gcc/testsuite/ChangeLog:

2019-11-08  Mihail Ionescu  <mihail.ionescu@arm.com>
2019-11-08  Andre Vieira  <andre.simoesdiasvieira@arm.com>

	* testsuite/gcc.target/arm/multilib.exp: Add v8.1-M entries.


Is this ok for trunk?

Best regards,

Mihail
