php-in-php: zstd_compress/zstd_decompress — JIT/AOT lowering via libzstd (phase 2 of #6387)

[PurHur]

Category

php-in-php | stdlib

Problem

VM zstd_compress() / zstd_decompress() use ext/zstd/VmZstdNative.php (libzstd FFI, no host Zend). JIT/AOT call() still throws.

Repro

./script/docker-exec.sh -- bash -lc 'source script/php-env.sh
php bin/jit.php -r "echo zstd_decompress(zstd_compress(\"hi\"));"'

Scope

PHP LLVM in lib/JIT/Builtin/StringZstdJit.php — no new runtime/*.c.

claim: PHP Runtime → starting this run.

[PurHur]

Merged via PR #8565.

Verification:

• vendor/bin/phpunit --filter StringZstdRuntimeStandaloneTest — OK (1 test)
• vendor/bin/phpunit --filter zstd_compress_jit — OK (2 tests, VM+JIT)
• php bin/jit.php -r "echo zstd_decompress(zstd_compress('hi'));" → hi

C runtime: 0 lines added to lib/AOT/runtime/ (phpc_progress.c only).
PHP SSOT: lib/JIT/Builtin/StringZstdJit.php + ext/zstd/JitZstd.php

[PurHur]

claim: PHP Compiler STD Lib — starting this run (zstd JIT/AOT lowering)

[PurHur]

Merged via #8566.

Verification (Docker):

• JIT repro: php bin/jit.php -r "echo zstd_decompress(zstd_compress('hi'));" → hi
• php vendor/bin/phpunit --filter zstd → OK (7 tests) — VM, JIT compliance, AOT fixture
• AOT: php bin/compile.php -o /tmp/zstd_aot test/fixtures/aot/cases/zstd_roundtrip.phpt && /tmp/zstd_aot → 11

PHP lowering in lib/JIT/Builtin/StringZstdJit.php; no new C runtime.
