6 years agoChange EQ_ATTR_ALT to support up to 64 alternatives
Ilya Leoshkevich [Mon, 24 Sep 2018 15:01:57 +0000 (15:01 +0000)]
Change EQ_ATTR_ALT to support up to 64 alternatives

On S/390 there is a need to support more than 32 instruction
alternatives per define_insn.  Currently this is not explicitly
prohibited or unsupported: MAX_RECOG_ALTERNATIVES is equal 35, and,
futhermore, the related code uses uint64_t for bitmaps in most places.

However, genattrtab contains the logic to convert (eq_attr "attribute"
"value") RTXs to (eq_attr_alt bitmap) RTXs, where bitmap contains
alternatives, whose "attribute" has the corresponding "value".
Unfortunately, bitmap is only 32 bits.

When adding the 33rd alternative, this led to (eq_attr "type" "larl")
becoming (eq_attr_alt -1050625 1), where -1050625 == 0xffeff7ff.  The
cleared bits 12, 21 and 32 correspond to two existing and one newly
added insn of type "larl".  compute_alternative_mask sign extended this
to 0xffffffffffeff7ff, which contained non-existent alternatives, and
this made simplify_test_exp fail with "invalid alternative specified".

I'm not sure why it didn't fail the same way before, since the top bit,
which led to sign extension, should have been set even with 32
alternatives.  Maybe simplify_test_exp was not called for "type"
attribute for some reason?

This patch widens EQ_ATTR_ALT bitmap to 64 bits, making it possible to
gracefully handle up to 64 alternatives.  It eliminates the problem with
the 33rd alternative on S/390.

S/390: Fix conditional returns on z196+

S/390 epilogue ends with (parallel [(return) (use %r14)]) instead of
the more usual (return) or (simple_return).  This sequence is not
recognized by the conditional return logic in try_optimize_cfg ().

This was introduced for processors older than z196, where it is
sometimes profitable to use call-clobbered register for returning
instead of %r14.  On newer processors we always return via %r14,
for which the fact that it's used is already reflected by
EPILOGUE_USES.  In this case a simple (return) suffices.

This patch changes return_use () to emit simple (return)s when
returning via %r14.  The resulting sequences are recognized by the
conditional return logic in try_optimize_cfg ().

6 years agoUse vectored writes when reporting errors and warnings.
Janne Blomqvist [Fri, 21 Sep 2018 18:12:59 +0000 (21:12 +0300)]
Use vectored writes when reporting errors and warnings.

When producing error and warning messages, libgfortran writes a
message by using many system calls.  By using vectored writes (the
POSIX writev function) when available and feasible to use without
major surgery, we reduce the chance that output gets intermingled with
other output to stderr.

In practice, this is done by introducing a new function estr_writev in
addition to the existing estr_write.  In order to use this, the old
st_vprintf is removed, replaced by direct calls of vsnprintf, allowing
more message batching.

However ::dump_loc doesn't filter with pflags and alt_flags.

6 years agoRemove constant vec_select restriction.
Andrew Stubbs [Wed, 19 Sep 2018 13:25:42 +0000 (13:25 +0000)]
Remove constant vec_select restriction.

The vec_select operator is documented to require a const_int for the lane
selector operand, but GCN has an instruction that can select the lane at
runtime, so it seems reasonable to remove this restriction.

This patch simply replaces assertions that the operand is constant with early
exits from the optimizers.  I think it's reasonable that vec_select with a
non-constant operand cannot be optimized, yet.

Also included is the necessary documentation tweak.

6 years ago[AARCH64] Use STLUR for atomic_store
Matthew Malcomson [Wed, 19 Sep 2018 10:24:59 +0000 (10:24 +0000)]
[AARCH64] Use STLUR for atomic_store

Use the STLUR instruction introduced in Armv8.4-a.
This instruction has the store-release semantic like STLR but can take a
9-bit unscaled signed immediate offset.

Example test case:
```
void
foo ()
{
    int32_t *atomic_vals = calloc (4, sizeof (int32_t));
    atomic_store_explicit (atomic_vals + 1, 2, memory_order_release);
}
```

Before patch generates
```
foo:
stp x29, x30, [sp, -16]!
mov x1, 4
mov x0, x1
mov x29, sp
bl calloc
mov w1, 2
add x0, x0, 4
stlr w1, [x0]
ldp x29, x30, [sp], 16
ret
```

After patch generates
```
foo:
stp x29, x30, [sp, -16]!
mov x1, 4
mov x0, x1
mov x29, sp
bl calloc
mov w1, 2
stlur w1, [x0, 4]
ldp x29, x30, [sp], 16
ret
```

We introduce a new feature flag to indicate the presence of this instruction.
The feature flag is called AARCH64_ISA_RCPC8_4 and is included when targeting
armv8.4 architecture.

We also introduce an "arch" attribute to be checked called "rcpc8_4" after this
feature flag.
