    The `serial' construct (cf. section 2.5.3 of the OpenACC 2.6 standard)
    is equivalent to a `parallel' construct with clauses `num_gangs(1)
    num_workers(1) vector_length(1)' implied.
    These clauses are therefore not supported with the `serial'
    construct. All the remaining clauses accepted with `parallel' are also
    accepted with `serial'.

    The `serial' construct is implemented like `parallel', except for
    hardcoding dimensions rather than taking them from the relevant
    clauses, in `expand_omp_target'.

    Separate codes are used to denote the `serial' construct throughout the
    middle end, even though the mapping of `serial' to an equivalent
    `parallel' construct could have been done in the individual language
    frontends. In particular, this allows to distinguish between compute
    constructs in warnings, error messages, dumps etc.

This PR was caused by the SLP handling in get_group_load_store_type
returning VMAT_CONTIGUOUS rather than VMAT_CONTIGUOUS_REVERSE for
downward groups.

A more elaborate fix would be to try to combine the reverse permutation
into SLP_TREE_LOAD_PERMUTATION for loads, but that's really a follow-on
optimisation and not backport material.  It might also not necessarily
be a win, if the target supports (say) reversing and odd/even swaps
as independent permutes but doesn't recognise the combined form.

Bump the minimum MPFR version to 3.1.0, released 2011-10-03. With this
requirement one can still build GCC with the operating system provided
MPFR on old but still supported operating systems like SLES 12 (MPFR
3.1.2) or RHEL/CentOS 7.x (MPFR 3.1.1).

This allows removing some code in the Fortran frontend, as well as

	* config/i386/intelmic-mkoffload.c (prepare_target_image): Put
	-fPIC and -shared the last to create offload image.

... to fix a long-time typo/copy'n'past-o.

	gcc/
	* gimplify.c (gimplify_scan_omp_clauses): Assert 'offset2' instead
	of 'offset'.

The 'gcc/configure' script sources all 'gcc/*/config-lang.in' files, but fails
to emit such dependency information into the build machinery.  That means,
currently, when something gets changed in a 'gcc/*/config-lang.in' file, this
is not noticed, and doesn't propagate through the build machinery.

Handling of configure fragments is modelled in the same way as it already
exists for Makefile fragments.

	gcc/
	* Makefile.in (LANG_CONFIGUREFRAGS): Define.
	(config.status): Use/depend on it.
	* configure.ac (all_lang_configurefrags): Track, 'AC_SUBST'.
	* configure: Regenerate.

In this patch, loop unroll adjust hook is introduced for powerpc.  We
can do target related heuristic adjustment in this hook.  In this patch,
-funroll-loops is enabled for small loops at O2 and above with an option
-munroll-small-loops to guard the small loops unrolling, and it works
fine with -flto.

To align with rs6000_insn_cost costing more for load type insns,
this patch is to make load insns cost more in vectorization cost
function.  The latency of load insns is about twice that of
"simple" instructions; 2 vs. 1 on older cores, and 4 (or so) vs.
2 on newer cores.  Considering that the result of load usually
is used somehow later (true-dep) but store won't, we keep the
store as before.

The SPEC2017 performance evaluation on Power8 shows 525.x264_r
+9.56%, 511.povray_r +2.08%, 527.cam4_r 1.16% gains, no 
significant degradation, SPECINT geomean +0.88%, SPECFP geomean
+0.26%.

The SPEC2017 performance evaluation on Power9 shows no significant
improvement or degradation, SPECINT geomean +0.04%, SPECFP geomean
+0.04%.

The SPEC2006 performance evaluation on Power8 shows 454.calculix
+4.41% gain but 416.gamess -1.19% and 453.povray -3.83% degradation.
I looked into the two degradation bmks, the degradation were NOT
due to hotspot changes by vectorization, were all side effects.
SPECINT geomean +0.10%, SPECFP geomean no changed considering
the degradation.

    * config/rs6000/rs6000.c (rs6000_builtin_vectorization_cost): Make
    scalar_load, vector_load, unaligned_load and vector_gather_load cost
    more to conform hardware latency and insn cost settings.
