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.
Top-level:
* contrib/gcc_update (files_and_dependencies): Remove stamp rules for
arm-specific auto-generated header files.
gcc:
* common/config/arm/arm-common.c: Adjust include path for
arm-cpu-cdata.h
* t-arm (TM_H): Adjust path for arm-cpu.h.
(arm-cpu.h): Create in build directory. Adjust dependency rules.
(arm-cpu-data.h): Likewise.
(arm-cpu-cdata.h): Likewise.
* config/arm/arm-cpu.h: Delete.
* config/arm/arm-cpu-cdata.h: Delete.
* config/arm/arm-cpu-data.h: Delete.

The files arm-cores.def, arm-fpus.def and arm-arches.def are parsed and
used in several places and the format is slightly awkward to maintain
as they must be parsable in C and by certain scripts. Furthermore,
changes to the content that affects every entry is particularly awkward for
dealing with merges.
This patch replaces all three files with a single file that specifies all
the command-line related definitions in a new format that allows for better
checking for consistency as well as (hopefully) easier to merge changes.
The awk script used to parse it is relatively complicated, but should be
pretty portable. It works by parsing in all the data and then operating
one of a number of possible sub-commands to generate the desired output.
The new method picked up one error. The CPU descriptions referred to an
architecture ARMv5tej which was not supported by -march. This has been
fixed by adding the relevant entry to the architecture list.

* config.gcc: Use new awk script to check CPU, FPU and architecture
parameters for --with-... options.

Commit the vtable verification feature. This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer.
If pointer corruption is detected, execution of the program is halted.
