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.

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.

Add support for profiledbootstrap with autofdo. Will be useful
to get better testing coverage of autofdo.
This requires Linux perf and autofdo to be installed, only
really for x86_64 linux on Intel so far.
Profile the whole build process with perf, then convert the file,
and pass it back to the compiler in the feedback stage.
The conversion has to be done per language, as only that knows
the name of the binary. Currently we only do it for C and C++,
as the other languages don't have enough coverage during a normal
bootstrap.
For lto1 it is also disabled, because it would only be useful during a LTO
bootstrap, but right now autofdo and LTO are not working together due to
PR66229
For common backend files always the profile output of the C++ compiler
is used. In theory multiple inputs could be merged here, but so far
that is not implemented.
The method is not friendly to partial rebuilds, as only the profile
information from the current rebuild is used. So if an error
occurs it is best to clean and restart, otherwise the code
quality may be worse.
This patch is fairly large, but most of it is auto generated from
autogen in Makefile.in. for the new stage targets.
Passes profiledbootstrap and normal bootstrap on x86_64-linux.
autoprofiledbootstrap is currently not working due to
PR70427 (but it finishes with that worked around)
The autofdo'ed compiler is ~7% faster on insn-recog.i (vs ~11% for
profiledfeedback), and ~4% faster for tramp3d-v4 (vs 10% for
profiledfeedback) on a Sandy Bridge system.

This patch changes some of the dejagnu options to better restrict
where the test cases run so that they will no longer cause failures on
power7 machines.

and in rs6000-c.c.

This patch adds support for the signed and unsigned int versions of the
vec_addec altivec builtins from the Power Architecture 64-Bit ELF V2 ABI
OpenPOWER ABI for Linux Supplement (16 July 2015 Version 1.1). There are
many of the builtins that are missing and this is part of a series
of patches to add them.
There aren't instructions for the int versions of vec_addec so the
output code is built from other built-ins that do have instructions
which in this case is the following.
vec_addec (va, vb, carryv) == vec_or (vec_addc (va, vb),
vec_addc(vec_add(va, vb),
vec_and (carryv, 0x1)))
The new test cases are executable tests which verify that the generated
code produces expected values. C macros were used so that the same
test case could be used for both the signed and unsigned versions. An
extra executable test case is also included to ensure that the modified
support for the __int128 versions of vec_addec is not broken. The same
test case could not be used for both int and __int128 because of some
differences in loading and storing the vectors.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu and
powerpc64-unknown-linux-gnu with no regressions. Is this ok for trunk?
