    • [arm] Move some generated files out of the source tree · 50061652 
      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.

    • [ARC]Fast interrupts support. · c7314bc1 
      When a processor enters a fast interrupts handler, and duplicate
register banks are configured, the processor saves the user context by
saving the registers in the main register bank to these additional
registers in the duplicate register bank.  In this fast interrupt
context, when you specify the rgf_banked_regs option,the compiler does
not save the registers duplicated in the additional register bank are
not saved.

    • [ARC] Automatic context save/restore for regular interrupts. · 41453183 
      The AUX_IRQ_CTRL register controls the behavior of automated register
save and restore or prologue and epilogue sequences during a non-fast
interrupt entry and exit, and context save and restore instructions.

A user passes to the compiler the configuration of the AUX_IRQ_CTRL
register via mirq-ctrl-saved option.  This option, specifies
gneral-purposes registers that the processor saves/restores on
interrupt entry and exit, and it is only valid for ARC EM and ARC HS
cores.
