[AArch64][2/2] Add sve_width -moverride tunable

On top of the previous patch that implements TARGET_ESTIMATED_POLY_VALUE
and adds an sve_width tuning field to the CPU structs, this patch implements
an -moverride knob to adjust this sve_width field to allow for experimentation.
Again, reminder that this only has an effect when compiling for VLA-SVE that is,
without msve-vector-bits=<foo>. This just adjusts tuning heuristics in the compiler,,
like profitability thresholds for vectorised versioned loops, and others.

It can be used, for example like -moverride=sve_width=256 to set the sve_width
tuning field to 256. Widths outside of the accepted SVE widths [128 - 2048] are rejected
as you'd expect.

[AArch64][1/2] Implement TARGET_ESTIMATED_POLY_VALUE

The hook TARGET_ESTIMATED_POLY_VALUE allows a target to give an estimate for a poly_int run-time value.
It is used exclusively in tuning decisions, things like estimated loop iterations, probabilities etc.
It is not relied on for correctness.

If we know the SVE width implemented in hardware we can make more more
informed decisions in the implementation of TARGET_ESTIMATED_POLY_VALUE,
even when compiling for VLA vectorisation.

This patch adds an sve_width field to our tuning structs and sets it for
the current CPU tunings.

A new value is introduced to the aarch64_sve_vector_bits_enum enum that indicates
that SVE is not available: SVE_NOT_IMPLEMENTED. I set it to the same value as SVE_SCALABLE
so that parts of the aarch64 backend that follow the pattern:
if (vector_width == SVE_SCALABLE)
  do_vla_friendly_action ()
else
  assume_specific_width_for_correctness ()

continue to work without change, but the CPU tuning structs can use a more
appropriate moniker for indicating the absence of SVE.

This sets sve_width to SVE_NOT_IMPLEMENTED for all cores.
I aim to add an -moverride switch in the next patch that allows a power user to experiment
with different values of it for investigations.

[PR86747] tsubst friend tpl ctxt before looking it up for dupes

When a member template is redeclared as a friend, we enter the context
of the member before looking it up, and then we check that the decls
are compatible.  However, when the member template references template
types of the enclosing context, say an enclosing template class, the
compare fails because the friend decl is already tsubsted, whereas the
looked up name isn't.

The problem is that the enclosing context is taken from the friend
declaration before tsubsting it, so we look up in the context of the
generic template instead of that of the tsubsted one we're
specializing.  The solution is to tsubst the enclosing context when
it's a non-namespace scope.

5 years agoavoid null ptr deref in cselib_record_sets
Alexandre Oliva [Thu, 6 Dec 2018 23:18:19 +0000 (23:18 +0000)]
avoid null ptr deref in cselib_record_sets

Jeff Law tells me h8300-elf fails gcc.c-torture/compile/pr49029.c
with -O2 -g -mint32 -mh.  This patch fixes it.

The problem is that strict low part handling in cselib_record_sets
assumes src_elt is not NULL.  That src_elt is taken from a strict low
part set, but it won't always have a src_elt to begin with.  In this
case, it's because src is a volatile MEM; we don't record values for
those.

Although we could fix the problem by testing for a NULL src_elt before
creating the zero extends corresponding to strict low part sets of
formerly const0_rtx REGs, there's no point in recording the additional
set that we won't be able to use anyway.

We could still record that the whole register has a zero-extend of
the value stored in the narrower-mode strict low part of the register,
but is that of any use?  I guess not, but if we find otherwise, we can
change that later.

5 years agoruntime: add precise stack scan support
Ian Lance Taylor [Wed, 5 Dec 2018 23:09:51 +0000 (23:09 +0000)]
runtime: add precise stack scan support

    This CL adds support of precise stack scan using stack maps to
    the runtime. The stack maps are generated by the compiler (if
    supported). Each safepoint is associated with a (real or dummy)
    landing pad, and its "type info" in the exception table is a
    pointer to the stack map. When a stack is scanned, the stack map
    is found by the stack unwinding code by inspecting the exception
    table (LSDA).

    For precise stack scan we need to unwind the stack. There are
    three cases:

    - If a goroutine is scanning its own stack, it can unwind the
      stack and scan the frames.

    - If a goroutine is scanning another, stopped, goroutine, it
      cannot directly unwind the target stack. We handle this by
      switching (runtime.gogo) to the target g, letting it unwind
      and scan the stack, and switch back.

    - If we are scanning a goroutine that is blocked in a syscall,
      we send a signal to the target goroutine's thread, and let the
      signal handler unwind and scan the stack. Extra care is needed
      as this races with enter/exit syscall.

    Currently this is only implemented on linux.

testsuite: turn down verbosity of "process-message"

When debugging a failing test, I typically invoke DejaGnu at
verbosity level 2 (via RUNTESTFLAGS="-v -v dg.exp=something"),
so that DejaGnu prints the command line used to invoke the
compiler; specifically these two sites:
  target.exp "Invoking the compiler as "
  remote.exp "Executing on $hostname"
which are both verbosity level 2.

Unfortunately I run into an O(n^2) issue with logging from
process-message:

  verbose "process-message:\n${dg-messages}" 2

where, as each message each processed, it emits the state
of dg-messages, containing the new message and all messages so far,
leading to exponentially-increasing output at level 2 as more test
messages are added.

This patch papers over the problem by moving the
problematic message to verbosity level 3.
