    • Add make autoprofiledbootstrap · 277d7ee0 
      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.

Based on a subsequent patch I also updated the code formatting (indentation,
etc.) for the code from the original patch (r235577) in both the test cases
and in rs6000-c.c.

    • This patch adds support for the signed and unsigned int versions of the... · 92466115 
      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?
