[Forwarding to gcc-patches, doh!]

Hi,
ARM-specific thumb2-slow-flash-data.c testcase shows 2 failures when running
for arm-none-eabi with -mcpu=cortex-m7:
FAIL: gcc.target/arm/thumb2-slow-flash-data.c (test for excess errors)
FAIL: gcc.target/arm/thumb2-slow-flash-data.c scan-assembler-times movt 13
The first one is due to a missing type specifier in the declaration of labelref
while the second one is due to different constant synthesis as a result of a
different tuning for the CPU selected. This patch fixes these issues by adding
the missing type specifier and checking for .word and similar directive instead
of the number of movt.
The new test passes for all of -mcpu=cortex-m{3,4,7} but fail when removing the
-mslow-flash-data switch.
ChangeLog entry is as follows:
*** gcc/testsuite/ChangeLog ***
2015-11-04 Thomas Preud'homme <thomas.preudho...@arm.com>
* gcc.target/arm/thumb2-slow-flash-data.c: Add missing typespec for
labelref and check use of constant pool by looking for .word and
similar directives.

Is this ok for trunk?
