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.

[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.

PR c++/89144 - link error with constexpr initializer_list.

In this PR, we were unnecessarily rejecting a constexpr initializer_list
with no elements.  This seems like a fairly useless degenerate case, but it
makes sense to avoid allocating an underlying array at all if there are no
elements and instead use a null pointer, like the initializer_list default
constructor.

If the (automatic storage duration) list does have initializer elements, we
continue to reject the declaration, because the initializer_list ends up
referring to an automatic storage duration temporary array, which is not a
suitable constant initializer.  If we make it static, it should be OK
because we refer to a static array.  The second hunk fixes that case.  It
also means we won't diagnose some real errors in templates, but those
diagnostics aren't required, and we'll get them when the template is
instantiated.

i386: Revert revision 268678 and revision 268657

i386 backend has

INT_MODE (OI, 32);
INT_MODE (XI, 64);

So, XI_MODE represents 64 INTEGER bytes = 64 * 8 = 512 bit operation,
in case of const_1, all 512 bits set.

We can load zeros with narrower instruction, (e.g. 256 bit by inherent
zeroing of highpart in case of 128 bit xor), so TImode in this case.

Some targets prefer V4SF mode, so they will emit float xorps for zeroing

Then the introduction of AVX512F fubared everything by overloading the
meaning of insn mode.

How should we use INSN mode,  MODE_XI, in standard_sse_constant_opcode
and patterns which use standard_sse_constant_opcode? 2 options:

1.  MODE_XI should only used to check if EXT_REX_SSE_REG_P is true
in any register operand.  The operand size must be determined by operand
itself , not by MODE_XI.  The operand encoding size should be determined
by the operand size, EXT_REX_SSE_REG_P and AVX512VL.
2. MODE_XI should be used to determine the operand encoding size.
EXT_REX_SSE_REG_P and AVX512VL should be checked for encoding
instructions.

rejected by s390_decompose_address ().

linemap_line_start: protect against location_t overflow (PR lto/88147)

PR lto/88147 reports an assertion failure due to a bogus location_t value
when adding a line to a pre-existing line map, when there's a large
difference between the two line numbers.

For some "large differences", this leads to a location_t value that exceeds
LINE_MAP_MAX_LOCATION, in which case linemap_line_start returns 0.  This
isn't ideal, but at least should lead to safe degradation of location
information.

However, if the difference is very large, it's possible for the line
number offset (relative to the start of the map) to be sufficiently large
that overflow occurs when left-shifted by the column-bits, and hence
the check against the LINE_MAP_MAX_LOCATION limit fails, leading to
a seemingly-valid location_t value, but encoding the wrong location.  This
triggers the assertion failure:
  linemap_assert (SOURCE_LINE (map, r) == to_line);

The fix (thanks to Martin) is to check for overflow when determining
whether to reuse an existing map, and to not reuse it if it would occur.

In all cases the compiler is now generating the expected code, since the tests
