Running Zend/zend_vm_gen.php on 32-bit system produces deprecation warnings

Description

The following code:

./buildconf
./configure --disable-all
make

Emits some warnings when executing the Zend/zend_vm_gen.php script during the build (this is output for PHP 8.4, but also 8.3 and 8.2 produces similar warnings):

Deprecated: Implicit conversion from float 2147483648 to int loses precision in /home/petk/projects/php-src/Zend/zend_vm_gen.php on line 2476
Deprecated: Implicit conversion from float 2147483648 to int loses precision in /home/petk/projects/php-src/Zend/zend_vm_gen.php on line 2537
...

This removes the warnings, but as this script is 3k lines long all-in-one PHP file, I think it's better someone looks at this if this is correct.

PHP Version

PHP 8.2

Operating System

32-bit *nix (for example Debian or FreeBSD)

Reproduisez l’avertissement avec ./buildconf, ./configure --disable-all et make sur un système 32 bits. Inspectez Zend/zend_vm_gen.php autour des lignes 2476 et 2537, puis vérifiez que la génération de la VM se termine sans avertissements de dépréciation et que le build généré reste valide.
