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.

This patch splits the auto-generated inline functions out of
insn-modes.h and puts them in a new header file, insn-modes-inline.h.
It also makes coretypes.h include these files directly, rather than
indirectly via machmode.h. This in turn allows insn-modes-inline.h
and machmode.h to come later in the include list, after wide-int.h.
This is useful for later patches.
insn-modes.h itself still needs to come first, since it provides
configuration information like MAX_BITSIZE_MODE_ANY_INT, which is
used to control the size of a wide_int.
The patch also makes the generator files include machmode.h
via coretypes.h. Previously they did it by more indirect means.
Finally, the patch makes wide-int-print.h available via coretypes.h
too. There didn't seem to be any reason to force only the print
routines to be included directly, and it would be painful to extend
that approach to the SVE patches.

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.

Using autofdo is currently something difficult. It requires using the
model specific branches taken event, which differs on different CPUs.
The example shown in the manual requires a special patched version of
perf that is non standard, and also will likely not work everywhere.
This patch adds a new gcc-auto-profile script that figures out the
correct event and runs perf.
This is needed to actually make use of autofdo in a generic way
in the build system and in the test suite.
Since maintaining the script would be somewhat tedious (needs changes
every time a new CPU comes out) I auto generated it from the online
Intel event database. The script to do that is in contrib and can be
rerun.
Right now there is no test if perf works in configure. This
would vary depending on the build and target system, and since
it currently doesn't work in virtualization and needs uptodate
kernel it may often fail in common distribution build setups.
So far the script is not installed.
