* Support prototypes in call graphNikita Popov2021-03-192-4/+7
| | | | | | | | | | Even if we don't know the exact method being called, include it in the call graph with the is_prototype flag. In particular, we can still make use of return types from prototype methods, as PHP 8 makes LSP violations a hard error. Most other places are adjusted to skip calls with !is_prototype. Maybe some of them would be fine, but ignoring them is conservative.

* | Optimize ZEND_COUNT opcodes on arrays in the jitTyson Andre2021-02-093-1/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid the overhead of a call and checking types when the argument is definitely an array. Avoid the overhead of gc when `__destruct` won't get called. This seemed cheap enough to check for in the jit. Because of https://wiki.php.net/rfc/restrict_globals_usage we can be sure in the ZEND_COUNT handler that the array count does not have to be recomputed in php 8.1. The below example took 0.854 seconds before the optimization, and 0.564 seconds after the optimization, giving the same result ```php <?php /** @jit */ function bench_count(int $n): int { $total = 0; $arr = []; for ($i = 0; $i < $n; $i++) { $arr[] = $i; $total += count($arr); } return $total; } function main() { $n = 1000; $iterations = 50000; $start = microtime(true); $result = 0; for ($i = 0; $i < $iterations; $i++) { $result += bench_count($n); } $elapsed = microtime(true) - $start; printf("Total for n=%d, iterations=%d = %d, elapsed=%.3f\n", $n, $iterations, $result, $elapsed); } main(); ``` Before ```asm mov $0x7feb8cf8a858, %r15 mov $ZEND_COUNT_SPEC_CV_UNUSED_HANDLER, %rax call *%rax ``` After ```asm mov 0x70(%r14), %rdi - Copy the count from the `zend_array*` pointer mov %rdi, (%rax) - Store the count in the destination's value mov $0x4, 0x8(%rax) - Store IS_LONG(4) in the destination's type ``` And add tracing jit support Closes GH-5584
* | Added Inheritance Cache.Dmitry Stogov2021-02-091-11/+15
| | | | | | | | | | | | | | | | | | | | This is a new transparent technology that eliminates overhead of PHP class inheritance. PHP classes are compiled and cached (by opcahce) separately, however their "linking" was done at run-time - on each request. The process of "linking" may involve a number of compatibility checks and borrowing methods/properties/constants form parent and traits. This takes significant time, but the result is the same on each request. Inheritance Cache performs "linking" for unique set of all the depending classes (parent, interfaces, traits, property types, method types involved into compatibility checks) once and stores result in opcache shared memory. As a part of the this patch, I removed limitations for immutable classes (unresolved constants, typed properties and covariant type checks). So now all classes stored in opcache are "immutable". They may be lazily loaded into process memory, if necessary, but this usually occurs just once (on first linking). The patch shows 8% improvement on Symphony "Hello World" app.

| | | | | | | | | | | | | | | | | | | | | | | | | | When one thread tries to compile a script, another thread may already be executing JITed code. In this case we can't make the memory non-executable. This violates the W^X principle, but doesn't seem to be avoidable for ZTS builds for now. The same problem does not exist for NTS, as it's a different process executing there, which has it's own memory protection mapping. Closes GH-6595.
