This is pretty unlikely in real code...

This is pretty unlikely in real code, but similar to Arm, the AArch64
ABI has a bug with the handling of 128-bit bit-fields, where if the
bit-field dominates the overall alignment the back-end code may end up
passing the argument correctly.  This is a regression that started in
gcc-6 when the ABI support code was updated to support overaligned
types.  The fix is very similar in concept to the Arm fix.  128-bit

[AArch64][SVE] Handle register-register pred_movs

pred_mov<mode> is defined for predicated loads and stores, where
exactly one of the operands is a register.  However, the instruction
condition only checked for "one" rather than "exactly one", and
Prathamesh found a case in which combine could fold a predicated
pattern to an all-register pred_mov<mode>.  The constraints would
then force one of the registers to memory.

This patch splits all-register forms into a normal move as soon
as possible, but also adds an all-register alternative in case the
instruction doesn't get split before RA (or in case the RA can use
inheritance to avoid a reload).

The testcase for this will be added to aarch64/sve-acle-branch.

[nvptx, libgomp] Fix cuMemAlloc with size zero

Consider test-case:
...
int
main (void)
{
  #pragma acc parallel async
  ;
  #pragma acc parallel async
  ;
  #pragma acc wait

  return 0;

This fails with:
...
libgomp: cuMemAlloc error: invalid argument
Segmentation fault (core dumped)
...
The cuMemAlloc error is due to the fact that we're try to allocate 0 bytes.

Fix this by preventing calling map_push with size zero argument in nvptx_exec.

This also has the consequence that for the abort-1.c test-case, we end up
calling cuMemFree during map_fini for the struct cuda_map allocated in
map_init, which fails because an abort happened.  Fix this by calling
cuMemFree with CUDA_CALL_NOCHECK in cuda_map_destroy.

Tom de Vries [Wed, 23 Jan 2019 08:16:42 +0000 (08:16 +0000)]
[nvptx, libgomp] Fix assert (!s->map->active) in map_fini

There are currently two situations where this assert triggers:
...
libgomp/plugin/plugin-nvptx.c: map_fini: Assertion `!s->map->active' failed.
...

First, in abort-1.c, a parallel region triggering an abort:
...
int
main (void)
{
  #pragma acc parallel
  abort ();

  return 0;
}
...

The abort is detected in nvptx_exec as the CUDA_ERROR_ILLEGAL_INSTRUCTION
return status of the cuStreamSynchronize call after kernel launch, which is
then handled by calling non-returning function GOMP_PLUGIN_fatal.
Consequently, the map_pop in nvptx_exec that in case of cuStreamSynchronize
success would remove or inactive the element added by the map_push earlier in
nvptx_exec, does not trigger.  With the element no longer active, but still
marked active and a member of s->map,  we run into the assert during
GOMP_OFFLOAD_fini_device, which is triggered from atexit handler
gomp_target_fini (which is triggered by the GOMP_PLUGIN_fatal mentioned above
calling exit).

Second, in pr88941.c, an async parallel region without wait:
...
int
main (void)
{
  #pragma acc parallel async
  ;

  /* no #pragma acc wait */
  return 0;
}
...

Because nvptx_exec is handling an async region, it does not call map_pop for
the element added by map_push, but schedules an kernel execution completion
event to call map_pop.  Again, we run into the assert during
GOMP_OFFLOAD_fini_device, which is triggered from atexit handler
gomp_target_fini, but the exit in this case is triggered by returning from main.
So either the kernel is still running, or the kernel has completed but the
corresponding event that is supposed to call map_pop is stuck in the event
queue, waiting for an event_gc.

Fix this by removing the assert, and skipping the freeing of device memory if
the map is still marked active (though in the async case, this is more a
workaround than an fix).

Tom de Vries [Wed, 23 Jan 2019 08:16:11 +0000 (08:16 +0000)]
[nvptx, libgomp] Fix map_push

The map field of a struct ptx_stream is a FIFO.  The FIFO is implemented as a
single linked list, with pop-from-the-front semantics.

The function map_pop pops an element, either by:
- deallocating the element, if there is more than one element
- or marking the element inactive, if there's only one element

The responsibility of map_push is to push an element to the back, as well as
selecting the element to push, by:
- allocating an element, or
- reusing the element at the front if inactive and big enough, or
- dropping the element at the front if inactive and not big enough, and
  allocating one that's big enough

The current implemention gets at least the first and most basic scenario wrong:

> map = cuda_map_create (size);

We create an element, and assign it to map.

> for (t = s->map; t->next != NULL; t = t->next)
>   ;

We determine the last element in the fifo.

> t->next = map;

We append the new element.

> s->map = map;

But here, we throw away the rest of the FIFO, and declare the FIFO to be just
the new element.

This problem causes the test-case asyncwait-1.c to fail intermittently on some
systems.  The pr87835.c test-case added here is a a minimized and modified
version of asyncwait-1.c (avoiding the kernel construct) that is more likely to
fail.

Fix this by rewriting map_pop more robustly, by:
- seperating the function in two phases: select element, push element
- when reusing or dropping an element, making sure that the element is cleanly
  popped from the queue
- rewriting the push element part in such a way that it can handle all cases
  without needing if statements, such that each line is exercised for each of
  the three cases.

Unfortunately another PCS bug has come to light with the layout of
structs whose alignment is dominated by a 64-bit bitfield element.
Such fields in the type list appear to have alignment 1, but in
reality, for the purposes of alignment of the underlying structure,
the alignment is derived from the underlying bitfield's type.  We've
been getting this wrong since support for over-aligned record types
was added several releases back.  Worse still, the existing code may
generate unaligned memory accesses that may fault on some versions of
the architecture.

I've taken the opportunity to add a few more tests that check the
passing arguments with overalignment in the PCS.  Looking through the
existing tests it looked like they were really only checking

5 years ago[RS6000] PR88614, output_operand: invalid %z value
Alan Modra [Tue, 22 Jan 2019 02:29:47 +0000 (12:59 +1030)]
[RS6000] PR88614, output_operand: invalid %z value

The direct cause of this PR is the fact that tls_gdld_nomark didn't
handle indirect calls.  Also, most indirect calls were being optimised
back to direct calls anyway, due to tls_gdld_nomark not checking any
of the parallel elements except the first (plus the extra element that
distinguishes this call from normal calls).  There were other unwanted
substitutions too.

So this patch attacks the problem of handling special calls in a
different way.  Rather than adding another element to the call insn
parallel to distinguish -mno-tls-markers __tls_get_addr calls from any
other calls, we now inspect the second CALL arg.  Each
call_value_nonlocal and call_value_indirect insn now checks for the
tlsgd/ld unspecs when !TARGET_TLS_MARKERS and emits the arg setup
insns.  I disallow the local call patterns since we'll only see local
calls to __tls_get_addr in testcases, and it doesn't seem a good idea
to complicate the patterns just for a minor optimisation.  Sibling
call insns aren't used for libcalls, so none of these insns need to
change.

The patch also fixes a minor problem with -mno-tls-markers
__tls_get_addr calls causing a "li 3,0" instruction to be emitted
prior to the arg setup instructions, due to using a libcall with one
arg.  That isn't correct when the call insn itself sets up its arg.
Also, I've tidied the V4 secure-plt calls, generating them in
rs6000_call_sysv rather than by splitting in rs6000.md.  The
CALL_INSN_FUNCTION_USAGE added in edit_tls_call_insn is no longer
needed (since git commit 0a4b5c66df9).

On the subject of unwanted substitutions, I also saw a
_GLOBAL_OFFSET_TABLE_ symbol_ref being substituted for the GOT reg,
resulting in code like "addi 3,_GLOBAL_OFFSET_TABLE_,tls_ld@got@tlsld".
Fixed by the unspec_tls change.
