Req #78270 [NEW]: Usage of __vectorcall convention with FFI

From: lisachenko dot it at gmail dot com Operating system: Windows x64 PHP version: 7.4.0alpha2 Package: Unknown/Other Function Bug Type: Feature/Change Request Bug description:Usage of __vectorcall convention with FFI Description: ------------ I'm trying to import AST internal PHP functions with FFI, but for Windows platform this brings a lot of pain, because __vectorcall convention is used. It was introduced in https://github.com/php/php-src/commit/3b6cd5fe4ce81d3d219887339f3915140214708c Unfortunately, libffi doesn't support vectorcall convention, thus symbol could not be imported properly with FFI. Is it possible to remove such specific calling convention, used for ZEND_FASTCALL macros for 7.4.0 and just switch to traditional one: __fastcall for x32. For x64 platform Expected result: ---------------- All exported PHP functions don't use vectorcall convention anymore. Actual result: -------------- Some PHP functions are exported as vectorcall-functions (have double @@ at the end with number of additional bytes), for example, "zend_ast_evaluate@@24" and could not be imported with FFI under Windows platform. -- Edit bug report at https://bugs.php.net/bug.php?id=78270&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=78270&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=78270&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=78270&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=78270&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78270&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78270&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78270&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78270&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78270&r=support Expected behavior: https://bugs.php.net/fix.php?id=78270&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78270&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78270&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78270&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=78270&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=78270&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78270&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78270&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78270&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78270&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78270&r=mysqlcfg
