Assertion `ctx->control' failed with new JIT and CALL VM

[pfustc]

Description

Hi @dstogov,

php: /tmp/php-src/ext/opcache/jit/ir/ir.c:2093: _ir_RETURN: Assertion `ctx->control' failed.

This is another assertion failure issue I see after the integration of the new JIT. It's reproducible with CALL VM and GCC global regs disabled on both x86 and AArch64. Please see below steps for details.

1. Checkout and build PHP with some configurations

$ cd /tmp
$ git clone git@github.com:php/php-src.git
$ cd php-src
$ php Zend/zend_vm_gen.php --with-vm-kind=CALL
$ bash buildconf
$ bash configure --enable-bcmath --enable-calendar --enable-dba --enable-debug --enable-exif \
  --enable-fpm --enable-ftp --enable-gd --enable-intl --enable-mbstring --enable-option-checking=fatal \
  --enable-pcntl --enable-phpdbg --enable-shmop --enable-soap --enable-sockets --enable-sysvmsg \
  --enable-sysvsem --enable-xmlreader --enable-zend-test --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd \
  --disable-gcc-global-regs
$ make

2. Checkout and build Laravel

$ cd /tmp
$ git clone https://github.com/laravel/framework.git
$ cd framework
$ composer install

3. Run Laravel tests with the PHP we just build

$ cd /tmp/framework
$ /tmp/php-src/sapi/cli/php -d zend_extension=/tmp/php-src/modules/opcache.so -d \
  opcache.jit_buffer_size=128M -d opcache.enable_cli=1 vendor/bin/phpunit
