Calls to gcc_jit_context_get_builtin_function that accessed builtins
in sanitizer.def and after (or failed to match any builtin) led to
a crash accessing a NULL builtin name.
The entries with the NULL name came from these lines in sanitizer.def:
/* This has to come before all the sanitizer builtins. */
DEF_BUILTIN_STUB(BEGIN_SANITIZER_BUILTINS, (const char *)0)
[...snip...]
/* This has to come after all the sanitizer builtins. */
DEF_BUILTIN_STUB(END_SANITIZER_BUILTINS, (const char *)0)
This patch updates jit-builtins.c to cope with such entries, fixing the
crash.

Epilogue vectorisation uses the vectorisation factor of the main loop
as the maximum vectorisation factor allowed for correctness. That makes
sense as a conservatively correct value, since the chosen vectorisation
factor will be strictly less than that anyway. However, once the VF
itself becomes variable, it's easier to carry across the original
maximum VF instead.

The vectoriser sometimes considers lowering "vector" operations into N
scalar word operations. This N needs to be fixed at compile time, so
the condition guarding it needs to change when variable-lengh vectors
are added. This patch puts the condition into a helper routine so that
there's only one place to update.

This patch adds a vectoriser helper routine to calculate how
many copies of a vector statement we need. At present this
is always:
LOOP_VINFO_VECT_FACTOR (loop_vinfo) / TYPE_VECTOR_SUBPARTS (vectype)
but later patches add other cases. Another benefit of using
a helper routine is that it can assert that the division is
exact (which it must be).

This patch adds gimple-fold.h equivalents of build_vector and
build_vector_from_val. Like the other gimple-fold.h routines
they always return a valid gimple value and add any new
statements to a given gimple_seq. In combination with later
patches this reduces the number of force_gimple_operands.

This patch makes can_vec_perm_p & co. take a vec<>, wrapped in new
typedefs vec_perm_indices and auto_vec_perm_indices. There are two
reasons for doing this for SVE:
(1) it means that the number of elements is bundled with the elements
themselves, and is obviously constant.
(2) it makes it easier to change the "unsigned char" element type to
something wider.
Changing the target hook is left as follow-on work.

This patch makes build_vector take the elements as a vec<> rather
than a tree *. This is useful for SVE because it bundles the number
of elements with the elements themselves, and enforces the fact that
the number is constant. Also, I think things like the folds can be used
with any generic GNU vector, not just those that match machine vectors,
so the arguments to XALLOCAVEC had no clear limit.

Previously VECTOR_CST_NELTS (t) read the number of elements from
TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling
this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the
number to a constant (which is doable) or store the number directly
in the VECTOR_CST. The latter seemed better, since it involves less
pointer chasing and since the tree_node u field is otherwise unused
for VECTOR_CST. It would still be easy to switch to the former in
future if we need to free up the field for someting else.
The patch also changes various bits of VECTOR_CST code to use
VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating
over VECTOR_CST_ELTs. Also, when the two are checked for equality,
the patch prefers to read VECTOR_CST_NELTS (which must be constant)
and check against TYPE_VECTOR_SUBPARTS, instead of the other way
around.

In preparation for upgrading libgo to the 1.9 release, this
approximately incorporates https://golang.org/cl/37661 and
https://golang.org/cl/38351.
CL 37661 changed the gc compiler such that the select statement simply
returns an integer which is then used as the argument for a switch.
Since gccgo already worked that way, this just adjusts the switch code
to look like the gc switch code by removing the explicit case index
expression and calculating it from the order of calls to selectsend,
selectrecv, and selectdefault.
CL 38351 simplifies the channel code by not passing the unused channel
type descriptor pointer.

This adds much of https://golang.org/cl/35731 and

This is a step toward updating libgo to the 1.9 release. The
gofrontend already supports type aliases, and this is required for
correct support of type aliases when used as embedded fields.
The change to expressions.cc is to handle the << 1, used for the

A normal pointer may not be converted to a notinheap pointer. We were
erroneously permitting a conversion from a normal pointer to a
notinheap unsafe.Pointer, which is useless since unsafe.Pointer is not
marked notinheap. Correct the test to permit a conversion from
unsafe.Pointer to a notinheap pointer, which is the same test that the
gc compiler uses.
The test case for this is in the 1.9 runtime package.

This includes a change to LRA. Previously the code was:
if (sclass == NO_REGS && dclass == NO_REGS)
return false;
#ifdef SECONDARY_MEMORY_NEEDED
if (SECONDARY_MEMORY_NEEDED (sclass, dclass, GET_MODE (src))
#ifdef SECONDARY_MEMORY_NEEDED_MODE
&& ((sclass != NO_REGS && dclass != NO_REGS)
|| GET_MODE (src) != SECONDARY_MEMORY_NEEDED_MODE (GET_MODE (src)))
#endif
)
{
*sec_mem_p = true;
return false;
}
#endif
in which the positioning of the second ifdef meant that defining
SECONDARY_MEMORY_NEEDED_MODE to its default value was not a no-op:
without a definition, we would consider using secondary reloads for
mem<-reg and reg<-mem reloads even if the secondary memory has the
same mode as the original mem, while defining it would avoid this.
The latter behaviour seems correct.
The default is different for reload and LRA. For LRA the default is
to use the original mode, while reload promotes smaller-than-word
integral modes to word mode:
if (GET_MODE_BITSIZE (mode) < BITS_PER_WORD && INTEGRAL_MODE_P (mode))
mode = mode_for_size (BITS_PER_WORD,
GET_MODE_CLASS (mode), 0).require ();
Some of the ports that have switched to LRA seemed to have
SECONDARY_MEMORY_NEEDED_MDOEs based on the old reload definition,
and still referred to the reload.c:get_secondary_mem function in
the comments. The patch just keeps them as-is.

This patch changes pr62178.c so that it now scans
for two `ldr`s, one into an `s` register, instead
of a `ld1r` as before. Also add a scan for an mla
instruction.
The `ld1r` was needed when this should have generated
a mla by vector. Now that we can generate an mla by
element instruction and can load directly into the
simd register, it is cheaper to not do the ld1r
which needlessly duplicates the single element used
across the whole vector register.

As Alexander pointed out in the thread starting at [1] the sort_by_bitpos sorting function
was behaving badly when we had multiple stores at the same position. He fixed that (thanks!)
but we can do better by not returning zero when the bitpositions are equal but by falling back
to comparing the order the stores appear in, which is guaranteed to be unique (barring other
bugs elsewhere).
This patch does that.
Bootstrapped and tested on aarch64-none-linux-gnu.

Coprocessor intrinsic tests in gcc.target/arm/acle test whether
__ARM_FEATURE_COPROC has the right bit defined before calling the
intrinsic. This allows to test both the correct setting of that macro
and the availability and correct working of the intrinsic. However the
__ARM_FEATURE_COPROC macro is no longer defined for ARMv8-A since
r249399.
This patch changes the testcases to skip that test for ARMv8-A and
ARMv8-R targets. It also fixes some irregularity in the coprocessor
effective targets:
- add ldcl and stcl to the list of instructions listed as guarded by
arm_coproc1_ok
- enable tests guarded by arm_coproc2_ok, arm_coproc3_ok and
arm_coproc4_ok for Thumb-2 capable targets but disable for Thumb-1
targets.
