The patch I committed yesterday to remove some generated headers from
the source tree unfortunately has a dependency missing that is only
revealed when doing a cross-native or full Canadian cross build. The
gen* programs were missing a dependency on one of the generated
headers.
Fixed by adding an explicit dependency rule for GTM_H in the same way
as we do for TM_H.
* config/arm/t-arm (GTM_H): Add arm-cpu.h.
Checked that this restores cross-native building.

This patch implements TARGET_FIXED_CONDITION_CODE_REGS on ARM.
We have two main cases to consider: in Thumb1 code there are no
condition code registers, so we simply return false. For other
cases we set the the first pointer to CC_REGNUM and the second to
VFPCC_REGNUM iff generating hard-float code.
Running the CSiBE benchmark I see a couple of cases (both in the same
file) where this feature kicks in, so it's not a major change.

While doing some unrelated work the gcc.target/aarch64/simd/vminmaxnm_1.c testcase started failing for me.
Upon investigation it turns out that it breaks the C strict aliasing rules in the CHECK macro by casting
a pointer to an incompatible type and dereferencing it. GCC even warns about it if compiled with -Wstrict-aliasing.
This patch fixes the testcase by making it use memcmp to compare the vector elements.
This avoids the undefined behaviour.
The testcase still passes on trunk.

When I originally started work on the new options framework for ARM
I'd worked on the assumption that AWK might not be available on every
build machine (only on developer's machines). However, looking again
I notice that all the options framework relies on it being present for
every build. This means that some of the generated files that come
from running parsecpu.awk do not need to be kept under revision
control.
Unfortunately, it's not _all_ generated files. The build
infrastructure assumes that all .md fragments are in the source tree
and similarly that all .opt fragments are there as well.
Still, eliminating the very big .h files is a step forward as they are
very regular in structure and diff/patch/merge tools can sometimes
make mistakes when resolving conflicts.
So this patch removes the generated .h files from the source tree and
tweaks the make rules accordingly. I've also changed the build rules
to use the stamp technique to eliminate some false dependencies in a
rebuild.

* contrib/gcc_update (files_and_dependencies): Remove stamp rules for
arm-specific auto-generated header files.

Much like my AArch64 patch a few weeks ago, this patch adds support
for the ARM Cortex-A75 and Cortex-A55 processors through the
-mcpu/-mtune values cortex-a55 and cortex-a75, and an
ARM DynamIQ big.LITTLE configuration of these two processors through
the -mcpu/-mtune value cortex-a75.cortex-a55
Both Cortex-A55 and Cortex-A75 support ARMv8-A with the ARM8.1-A and
ARMv8.2-A extensions. This is reflected in the patch, -mcpu=cortex-a75 is
treated as equivalent to passing -mtune=cortex-a75 -march=armv8.2-a+fp16

r249880 installed the result of a strlen in a strinfo if the strinfo
wasn't previously a full string. But as Jakub says in the PR comments,
we can't just do that in isolation, because there are no vdefs on the
call that would invalidate any related strinfos.
This patch updates the related strinfos if the adjustment is simple and
invalidates them otherwise. As elsewhere, we treat adjustments of the
form strlen +/- INTEGER_CST as simple but anything else as too complex.
