This removes the -maltivec=be and -maltivec=le options.  Those were
deprecated in GCC 8.

Altivec will keep working on both BE and LE; it is just the BE-vectors-
on-LE that is removed (the other way around was never supported).

(and then simplifying).

    Several recent changes to the gc version of cmd/go improve the
    gofrontend support. These changes are partially copies of existing
    gofrontend differences, and partially new code. This CL makes the
    gofrontend match the upstream code.
    
    The changes included here come from:
        https://golang.org/cl/111575
        https://golang.org/cl/111595
        https://golang.org/cl/111635
        https://golang.org/cl/111636
    
    For the record, the following recent gc changes are based on code
    already present in the gofrontend repo:
        https://golang.org/cl/110915
        https://golang.org/cl/111615
    
    For the record, a gc change, partially based on earlier gofrontend
    work, also with new gc code, was already copied to gofrontend repo in
    CL 111099:

To satisfy the CopyConstructible requirement a callable object stored in
a std::function must behave the same when copied from a const or
non-const source. If copying a non-const object doesn't produce an
equivalent copy then the behaviour is undefined. But we can make our
std::function more tolerant of such objects by ensuring we always copy
from a const lvalue.

Additionally use an if constexpr statement in the _M_get_pointer
function to avoid unnecessary instantiations in the discarded branch.

The one for the prologue mflr did not have any value set, which means
use the SET that is in the insn pattern.  This works fine, except when
some late pass decides to replace the SET_SRC -- this changes the
meaning of the REG_CFA_REGISTER!  Such passes should not do these
things, but let's be more explicit here, for extra robustness.  It
could be argued that this defaulting is a design misfeature (it does
not save much space either, etc.)


	PR rtl-optimization/85645
	* config/rs6000/rs6000.c (rs6000_emit_prologue_components): Put a SET
	in the REG_CFA_REGISTER note for LR, don't leave it empty.

From-SVN: r260077

In the testcase for PR85645 we do a pretty dumb placement of the
prologue/epilogue for the LR component: we place an epilogue for LR
before a control flow split where one of the branches clobbers LR
eventually, and the other does not.  The branch that does clobber it
will need a prologue again some time later.  Because saving and
restoring LR is a two step process---it needs to be moved via a GPR---
the backend emits CFI directives so that we get correct unwind
information.  But both regcprop and regrename do not properly handle
such CFI directives leading to ICEs.

Now, neither of the two branches needs to have LR restored at all,
because both of the branches end up in an infinite loop.

This patch makes spread_component return a boolean saying if anything
was changed, and if so, it is called again.  This obviously is finite
(there is a finite number of basic blocks, each with a finite number
of components, and spread_components can only assign more components
to a block, never less).  I also instrumented the code, and on a
bootstrap+regtest spread_components made changes a maximum of two
times.  Interestingly though it made changes on two iterations in
a third of the cases it did anything at all!


	PR rtl-optimization/85645

We should never change the destination of a REG_CFA_REGISTER, just
like for insns with a REG_CFA_RESTORE, because we need to have the
same control flow information on all branches that join.  It is very
doubtful that renaming the scratch registers used for prologue/epilogue
will help anything either.

	* regrename.c (build_def_use): Also kill the chains that include the

From-SVN: r260075

Changing a SET that has a REG_CFA_REGISTER note is wrong if we are
changing the SET_DEST, or if the REG_CFA_REGISTER has nil as its
argument, and maybe some other cases.  It's never really useful to
propagate into such an instruction, so let's just bail whenever we
see such a note.

	*  regcprop.c (copyprop_hardreg_forward_1): Don't propagate into an

We build up the input to IFN_STORE_LANES one vector at a time.
In RTL, each of these vector assignments becomes a write to
subregs of the form (subreg:VEC (reg:AGGR R)), where R is the
eventual input to the store lanes instruction.  The problem is
that RTL isn't very good at tracking liveness when things are
initialised piecemeal by subregs, so R tends to end up being
live on all paths from the entry block to the store.  This in
turn leads to unnecessary spilling around calls, as well as to
excess register pressure in vector loops.

This patch adds gimple clobbers to indicate the liveness of the
IFN_STORE_LANES variable and makes sure that gimple clobbers are
expanded to rtl clobbers where useful.  For consistency it also
uses clobbers to mark the point at which an IFN_LOAD_LANES
variable is no longer needed.
