Language: exit(status:)/die(status:) named parameters — parse error without PHP_COMPILER_PROFILE=8.4 (Zend/zend_compile.c)

Problem

PHP 8.4 allows named parameters on exit/die (exit(status: 0)). With PHP_COMPILER_PROFILE=8.4, this compiler accepts and runs the form; on the default reference profile it fails at parse time (unexpected token ":"). Forward-profile gating should not block syntax that Zend 8.4 accepts when the compilation unit targets 8.4 semantics.

Repro	Zend 8.4	VM default profile (2026-07-10)	VM `PHP_COMPILER_PROFILE=8.4`
`exit(status: 0);`	exit 0	`syntax error, unexpected token ":"`	exit 0

php-src reference

php/php-src Zend/zend_compile.c — exit/die named arg parsing (PHP 8.4)
php/php-src ext/standard/basic_functions.c — exit/die handlers

PHP implementation target

lib/ parser/compile — accept exit(status:) / die(status:) on PHP 8.4 forward profile without requiring ad-hoc env at parse time when project profile is 8.4
Lowering in PHP (ext/standard exit/die builtins), not new C runtime branches

Repro

./script/docker-exec.sh -- bash -lc 'php bin/vm.php test/repro/maintainer_gap_exit_named_status.php'  # expect fail today
PHP_COMPILER_PROFILE=8.4 php bin/vm.php test/repro/maintainer_gap_exit_named_status.php  # expect exit 0

Done when

test/repro/maintainer_gap_exit_named_status.php and maintainer_gap_die_named_status.php succeed under PHP 8.4 profile without parse errors on default when profile requests 8.4
Compliance guard under test/compliance/cases/language/exit_die_named_status_84.phpt
php-src-strict on 8.4 profile; no php-compiler-strict shortcut

Language: exit(status:)/die(status:) without CLI profile env (#17681) (…

Merged via #17685

Fix: LanguageProfileScope applies phpc.json languageProfile or // php-compiler-language-profile=8.4 before preprocess gates; supportsExitFunctionForm() aligned with other 8.4 forward-profile syntax gates.

Verification:

php bin/vm.php test/repro/maintainer_gap_exit_named_status.php → exit 0 (no CLI env)
php bin/vm.php test/repro/maintainer_gap_die_named_status.php → exit 1
vendor/bin/phpunit --filter LanguageProfileScopeTest → OK (3 tests)
vendor/bin/phpunit --filter "exit_die_named_status_84|exit_named_status_reference" test/compliance/VMTest.php → OK (2 tests)
php script/bootstrap-inventory.php --check → OK 4338/4338
make bootstrap-selfhost-vm-driver-execute-probe → OK

Merged via #17692.

Fix: Added lib/LanguageProfileScope.php to the M2 self-host spine bundle (4337→4338). Regenerated bootstrap inventory/profile and updated spine footnotes.

Verification:

php script/check-selfhost-spine-coverage-sync.php  # OK 4338/4338
