Extend tree code folds to IFN_COND_*
This patch adds match.pd support for applying normal folds to their
IFN_COND_* forms. E.g. the rule:
(plus @0 (negate @1)) -> (minus @0 @1)
also allows the fold:
(IFN_COND_ADD @0 @1 (negate @2) @3) -> (IFN_COND_SUB @0 @1 @2 @3)
Actually doing this by direct matches in gimple-match.c would
probably lead to combinatorial explosion, so instead, the patch
makes gimple_match_op carry a condition under which the operation
happens ("cond"), and the value to use when the condition is false
("else_value"). Thus in the example above we'd do the following
(a) convert:
cond:NULL_TREE (IFN_COND_ADD @0 @1 @4 @3) else_value:NULL_TREE
to:
cond:@0 (plus @1 @4) else_value:@3
(b) apply gimple_resimplify to (plus @1 @4)
(c) reintroduce cond and else_value when constructing the result.
Nested operations inherit the condition of the outer operation
(so that we don't introduce extra faults) but have a null else_value.
If we try to build such an operation, the target gets to choose what
else_value it can handle efficiently: obvious choices include one of
the operands or a zero constant. (The alternative would be to have some
representation for an undefined value, but that seems a bit invasive,
and isn't likely to be useful here.)
I've made the condition a mandatory part of the gimple_match_op
constructor so that it doesn't accidentally get dropped.

[arm] Put CPU's FPU capabilities directly in the ISA specification
As part of the transition from the original support for named FPUs to
general FPU properties I defined an entry in the CPU definitions in
arm-cpus.in to use a named FPU. However, that has now outlived its
usefulness and increasingly we are likely to find that newer cores do
not fit the legacy FPU names very well. Furthermore it is now possible
to encode all the FPU capatilities directly in the ISA definitions, often
as simply as using +fp or +simd.
So this patch removes the fpu field from the "define cpu" entries and
instead encodes the same information in the isa field. This also alows us
to remove a bit of now-dead code from parsecpu.awk.

compiler: fix double evaluation with interface field expression
In Interface_field_reference_expression, the interface expression
is used in two places, so a temporary variable is used. Previously,
we used a Set_and_use_temporary_expression, which, when evaluated
twice, causes double evaluation of the underlying expression. Fix
by setting the temporary once and use Temporary_reference_expression
instead.
Fixes golang/go#26248.

[debug] Handle debug references to skipped params
When compiling guality/vla-1.c with -O3 -g, vla a in f1 is optimized away, but
f1 still contains a debug expression describing the upper bound of the vla
(D.1914):
...
__attribute__((noinline))
f1 (intD.6 iD.1900)
{
<bb 2>
saved_stack.1_2 = __builtin_stack_save ();
# DEBUG BEGIN_STMT
# DEBUG D#3 => i_1(D) + 1
# DEBUG D#2 => (long intD.8) D#3
# DEBUG D#1 => D#2 + -1
# DEBUG D.1914 => (sizetype) D#1
...
Then f1 is cloned to a version f1.constprop with no parameters, eliminating
parameter i, and 'DEBUG D#3 => i_1(D) + 1' turns into 'D#3 => NULL'.
This patch fixes that by defining debug expressions for default defs of
eliminated parameters in remap_ssa_name:
...
__attribute__((noinline))
f1.constprop ()
{
intD.6 iD.1949;
<bb 3>
# DEBUG D#8 s=> iD.1900
# DEBUG iD.1949 => D#8
<bb 2>
+ # DEBUG D#6 s=> iD.1949
saved_stack.1_1 = __builtin_stack_save ();
# DEBUG BEGIN_STMT
- # DEBUG D#3 => NULL
+ # DEBUG D#3 => D#6 + 1
# DEBUG D#2 => (long intD.8) D#3
# DEBUG D#1 => D#2 + -1
# DEBUG D.1951 => (sizetype) D#1
...

Simplify movmem code by always doing overlapping copies when larger than 8 bytes on AArch64.
This changes the movmem code in AArch64 that does copy for data between 4 and 7
bytes to use the smallest possible mode capable of copying the remaining bytes in one
go and then overlapping the reads if needed.
This means that if we're copying 5 bytes we would issue an SImode and QImode
load instead of two SImode loads.
This does smaller memory accesses but also gives the mid-end a chance to realise
that it can CSE the loads in certain circumstances. e.g. when you have something
like
return foo;
where foo is a struct. This would be transformed by the mid-end into SSA form as
D.XXXX = foo;
return D.XXXX;
This movmem routine will handle the first copy, but it's usually not needed,
the mid-end would do SImode and QImode stores into X0 for the 5 bytes example
but without the first copies being in the same mode, it doesn't know it doesn't
need the stores at all.
