php-in-php: nextafter() JIT via NextafterJitHelper PHP — drop libc LLVM bridge (#1492) #15062
Description
Category
php-in-php · shrink JIT LLVM
Problem
ext/standard/nextafter.php JIT call() lowers operands then invokes libc nextafter via lookupFunction('nextafter'). VM path already uses VmMath::nextafter() PHP.
php-src reference
- ext/standard/math.c — PHP_FUNCTION(nextafter)
Repro
wc -l ext/standard/nextafter.php
./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
vendor/bin/phpunit --filter nextafter
