* fix(compiler): support first-class callable of internal functions
PHP 8.1 `foo(...)` builds a Closure from a single VariadicPlaceholder
argument instead of calling foo. Two paths mishandled it:
- checkInternalFunctionArgCount() counted the placeholder as a real
argument, so first-class callables of internal functions requiring 2+
parameters (e.g. `posix_kill(...)`) failed with a bogus "expects at
least N arguments, 1 given".
- The math-function return-type optimization read `$expr->args[0]->value`
on callables such as `round(...)`, crashing on the undefined
VariadicPlaceholder::$value property.
Guard both with isFirstClassCallable() so the expression falls through to
Closure (Type::OBJECT) resolution.
* fix(compiler): infer builtin callables before return optimizations

The >=16-significant-digit float-literal-to-php::Decimal promotion
(docs/en/HIGH_PRECISION_TYPES.md) counted every digit in the raw
literal with preg_replace('/[^0-9]/'), so exponent digits and trailing
zeros counted as significant: 1.23456789012345e300 (15 significant
digits) and 999999999999999.0 became Decimal, making
is_float(2.220446049250313E-16) compile to false. Hex literals whose
digits contain E (0x123456789E1234567) matched the [.eE] test and
became Decimal("0x..."), where Zend folds an overflowing hex literal
to its exact double.
Three fixes, keeping the documented feature:
- Count true mantissa significant digits (strip sign, exponent,
leading and trailing zeros) and additionally require that the double
cannot reproduce the literal exactly - a literal that round-trips
(every var_export/serialize output, PHP_FLOAT_EPSILON) has lost
nothing and stays float, while 3.14159265358979323846 still promotes.
- Exclude hex/octal/binary notation from the reclassification.
- When a Decimal-classified literal meets a float-typed expression in
a binary op or comparison, demote the literal to its exact double
instead of the "Cannot convert float expression to Decimal" fatal:
PHP evaluates every float literal as a double, so
0.1 + 0.2 == 0.30000000000000004 is valid PHP and must be true.
The classMethodOverride registration in prepareClassMethod() depends on
file preprocessing order. With a "sandwich" order (ancestor first, leaf
second, intermediate class last), the ancestor method's override flag is
missed: the upward marking cannot cross the not-yet-registered
intermediate class, and the downward subclass lookup ran before the leaf
was prepared. findNativeMethod() then devirtualizes the late-bound call
into a direct native call, silently ignoring the override. In Hyperf this
turns SoftDeletes::delete() into a physical DELETE.
Finalize the flags once the complete class graph is known:
finalizeMethodOverrideFlags() walks every declared method's complete
parent chain and marks each existing ancestor method of the same name as
overridden (method count x inheritance depth). It runs from
Translator::convertFile() next to finalizeDeclarationExpressions(), so
both the project pipeline and the public prepareFile()/convertFile() API
share the same pre-conversion finalization, guarded by a dirty/finalized
flag reset in prepareFile().
Tests:
- tests/compiler/devirtualize/override-order-sandwich.phpt (fails on
master with "base", passes with "leaf")
- tests/compiler/devirtualize/override-order-normal.phpt (control)
- phpunit/src/DevirtualizeOrderTest.php driving the public
prepareFile()/convertFile() API in both orders, asserting the
generated Base::delete() body dispatches dynamically
Consolidate float-to-C++ literal generation into Utils::genFloatLiteral().
Previously:
- genCValue() stringified floats directly via (string), emitting 'INF', '-INF', 'NAN', or losing the floating-point decimal point for whole numbers like 1.0 -> '1'.
- BinaryOpTrait::genFloatLiteral() used sprintf('%.17g') without handling INF or NAN.
Now all float code generation paths delegate to Utils::genFloatLiteral(), mapping INF/-INF/NAN to std::numeric_limits<double> and ensuring whole numbers retain .0.
The flag checks that translate `break N` / `continue N` were emitted only
at the end of each enclosing loop body. After the inner construct exited
with the countdown flag set, every trailing statement of the enclosing
body still executed before the check ran:
foreach ([1] as $x) {
foreach ([1] as $y) { break 2; }
echo "leaked"; // ran in compiled output, not in PHP
}
The native (int-typed) switch path was worse: its check sat inside the
do-while(0) wrapper, decrementing the flag a second time for the switch
level the C++ `break` had already exited. A `break 2` from a native
switch inside a loop therefore never exited the loop at all.
Emit the propagation check immediately after every nested loop / switch
statement instead, from the statement dispatcher, and drop the dead
end-of-body emissions. The check now also distinguishes the enclosing
construct: when it sits inside a switch, a continue that lands on the
switch level lowers to `break`, matching PHP's continue-targets-switch
semantics.
parseBreak/parseContinue now reject levels exceeding the number of
enclosing breakable constructs - the same compile-time validation PHP
performs (`Cannot 'break' 2 levels`) - which the countdown scheme
relies on to terminate at an enclosing construct.
The continue-2-while scenario in break-continue-level.phpt encoded the
old leaked behavior: its `$i++` after the inner loop only ran because of
the misplaced check; standard PHP loops forever on it. The counter now
advances before the inner loop.
