[RS6000] Fix <bd>_<mode> and <bd>tf_<mode> splitters

This patch fixes a bug that can result in "insn does not satisfy its
constraints" if these splitters fire due to not getting ctr for the
jump insn.  Since the jump insn can have any of r,m,d,wi,c,l as the
decremented count output, it's not sufficient to check for
gpc_reg_operand (which matches VSX regs for example).  Seen after
correcting register_move_cost when the cost of gpr <-> vsx is much
lower.  Since this is a prerequisite to fixing PR89271, I'm mentioning
that PR in the ChangeLog.

The <bd>tf_<mode> split had a further bug in that it wouldn't match
if the count output was m,d,wi, or l.

PR target/89271

Fix excess warnings from -Wtype-limits with location wrappers (PR c++/88680)

PR c++/88680 reports excess warnings from -Wtype-limits after the C++
FE's use of location wrappers was extended in r267272 for cases such as:

  const unsigned n = 8;
  static_assert (n >= 0 && n % 2 == 0, "");

t.C:3:18: warning: comparison of unsigned expression >= 0 is always true
  [-Wtype-limits]
    3 | static_assert (n >= 0 && n % 2 == 0, "");
      |                ~~^~~~

The root cause is that the location wrapper around "n" breaks the
suppression of the warning for the "if OP0 is a constant that is >= 0"
case.

This patch fixes it by calling fold_for_warn on OP0, extracting the
constant.

Cherry Zhang [Fri, 15 Feb 2019 23:22:29 +0000 (23:22 +0000)]
compiler,runtime: use __builtin_dwarf_cfa for getcallersp

    Currently, the compiler lowers runtime.getcallersp to
    __builtin_frame_address(1). In the C side of the runtime,
    getcallersp is defined as __builtin_frame_address(0). They don't
    match. Further, neither of them actually returns the caller's SP.
    On AMD64, __builtin_frame_address(0) just returns the frame
    pointer. __builtin_frame_address(1) returns the memory content
    where the frame pointer points to, which is typically the
    caller's frame pointer but can also be garbage if the frame
    pointer is not enabled.

    This CL changes it to use __builtin_dwarf_cfa(), which returns
    the caller's SP at the call site. This matches the SP we get
    from unwinding the stack.

    Currently getcallersp is not used for anything real. It will be
    used for precise stack scan (a new version of CL 159098).

Arm: Remove alternative from neon_softfp_fp16 directive.

There's a bit of a disconnect between the feature flags that don't test the fpu

of the architecture would change the defaults and without explicitly giving the
correct fpu again the test would fail.

I don't see a good way to solve this problem, really the feature tests should
ideally contain the extra options the test adds too, but for this specific case
it can be solved by always testing the fpu explicitly.

5 years agoDR 2586 fix value category in uses-allocator checks
Jonathan Wakely [Thu, 14 Feb 2019 15:08:33 +0000 (15:08 +0000)]
DR 2586 fix value category in uses-allocator checks

Because uses-allocator construction is invariably done with a const
lvalue the __uses_alloc helper should use a const lvalue for the
is_constructible checks. Otherwise, it can detect that the type can be
constructed from an rvalue, and then an error happens when a const
lvalue is passed to the constructor instead.

Prior to LWG DR 2586 scoped_allocator_adaptor incorrectly used an rvalue
type in the is_constructible check and then used a non-const lvalue for
the actual construction. The other components using uses-allocator
construction (tuple and polymorphic_allocator) have always done so with
a const lvalue allocator, although the use of __use_alloc in our
implementation meant they behaved the same as scoped_allocator_adaptor
and incorrectly used rvalues for the is_constructible checks.

In C++20 the P0591R4 changes mean that all uses-allocator construction
is defined in terms of the new uses_allocator_construction_args
functions, which always use a const lvalue allocator.

The changes in this patch ensure that the __use_alloc helper correctly
matches the requirements in the standard, consistently using a const
lvalue allocator for the is_constructible checks and the actual
constructor arguments.

PR libstdc++/89345 Only define std::destroying_delete for C++2a

Clang defines the __cpp_impl_destroying_delete macro unconditionally, so
that the feature is supported whenever the library type is defined. This
is incompatible with the current definition in libstdc++ because we use
constexpr and inline variables, which will give an error for older -std
modes.

This patch defines the destroying_delete_t type and destroying_delete
variable independently of the __cpp_impl_destroying_delete macro, but
only for C++2a (because the names aren't reserved for previous
standards). The __cpp_lib_destroying_delete macro is only defined when
both the library type and compiler macro are defined (i.e. when the type
can actually be used as intended).

[PR86379] do not use TREE_TYPE for USING_DECL_SCOPE

It's too risky to reuse the type field for USING_DECL_SCOPE.
Language-independent parts of the compiler, such as location and
non-lvalue wrappers, happily take the TREE_TYPE of a USING_DECL as if
it was a type rather than an unrelated scope.

For better or worse, USING_DECLs use the non-common struct so we can
use the otherwise unused result field.  Adjust fallout, from uses of
TREE_TYPE that were supposed to be USING_DECL_SCOPE, to other
accidental uses of TREE_TYPE of a USING_DECL.

5 years ago[PR87322] move cp_evaluated up to tsubst all lambda parms

[PR87322] move cp_evaluated up to tsubst all lambda parms

A lambda capture variable initialized with a lambda expr taking more
than one parameter got us confused.

The first problem was that the parameter list was cut short during
tsubsting because we tsubsted it with cp_unevaluated_operand.  We
reset it right after, to tsubst the function body, so I've moved the
reset up so that it's in effect while processing the parameters as
well.

The second problem was that the lambda expr appeared twice, once in a
decltype that gave the capture variable its type, and once in its
initializer.  This caused us to instantiate two separate lambda exprs
and closure types, and then to flag that the lambda expr in the
initializer could not be converted to the unrelated closure type
determined for the capture variable.  Recording the tsubsted expr in
the local specialization map, and retrieving it for reuse fixed it.
However, that required some care to avoid reusing the lambda expr
across different indices in pack expansions.
