[ARC] Recognise add_n and sub_n in combine again

Since the combine pass canonicalises shift-add insns using plus and
ashift (as opposed to plus and mult which it previously used to do), it
no longer creates *add_n or *sub_n insns, as the patterns match plus and
mult only. The outcome of this is that some opportunities to generate
add{1,2,3} and sub{1,2,3} instructions are missed.

This change adds additional *add_n and *sub_n insns that match the
plus-ashift pattern. The original *add_n and *sub_n insns are still left
in, as they are sometimes generated later on by constant propagation.
The idea of adding these insns is modelled on the changes in:

  https://gcc.gnu.org/ml/gcc-patches/2015-05/msg01882.html

which addresses a similar issue for the PA target.

For the small test cases that are added, even if the combine pass misses
the opportunity to generate addN or subN, constant propagation manages
to do so, so the rtl of the combine pass is checked.

Richard Sandiford [Wed, 31 May 2017 12:05:10 +0000 (12:05 +0000)]
Alternative check for vector refs with same alignment

vect_find_same_alignment_drs uses the ddr dependence distance
to tell whether two references have the same alignment.  Although
that's safe with the current code, there's no particular reason
why a dependence distance of 0 should mean that the accesses start
on the same byte.  E.g. a reference to a full complex value could
in principle depend on a reference to the imaginary component.
A later patch adds support for this kind of dependence.

On the other side, checking modulo vf is pessimistic when the step
divided by the element size is a factor of 2.

This patch instead looks for cases in which the drs have the same
base, offset and step, and for which the difference in their constant
initial values is a multiple of the alignment.

Segher Boessenkool [Tue, 30 May 2017 19:34:36 +0000 (21:34 +0200)]
Remove gen_cell_microcode, warn_cell_microcode

-mno-gen-cell-microcode is a pain to handle correctly: it causes
different code generation for some very basic patterns, even patterns
specific to that option.  It also requires marking up many patterns,
which is a pain when adding new patterns or modifying existing ones
(first non-trivial step is finding the Cell BE manual!)

-mwarn-cell-microcode is very expensive, even more so after my recent
fix for PR43763; and it used to ICE for seven years before that fix.

This patch removes both these command line options (it leaves the
positive form of -mgen-cell-microcode, doing nothing, for
compatibility).

Where cc_reg_not_micro_cr0_operand was used, we now get the regular
cc_reg_not_cr0_operand.

One testcase used -mgen-cell-microcode and one its negation; both
are adjusted.
