Bug #55874 [NEW]: GCC does not provide __sync_fetch_and_add on some archs

From: Operating system: Linux PHP version: trunk-SVN-2011-10-08 (SVN) Package: Compile Failure Bug Type: Bug Bug description:GCC does not provide __sync_fetch_and_add on some archs Description: ------------ Compilation currently fails on architectures without support for interlocked add, compare and swap, or a kernel cmpxchg helper, which includes: * PA-RISC with anything other than Linux * SPARCv7 and lower * ARM with GCC < 4.3 * ARMv5 and lower with anything other than Linux * MIPS1 ext/standard/php_crypt_r.c currently tries to use __sync_fetch_and_add when the compiler is at least GCC 4.1.2 and the OS is neither HP-UX nor HP-PA. Realistically, it should check that __sync_fetch_and_add is actually provided by the compiler. -- Edit bug report at https://bugs.php.net/bug.php?id=55874&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=55874&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=55874&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=55874&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=55874&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=55874&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=55874&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=55874&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=55874&r=needscript Try newer version: https://bugs.php.net/fix.php?id=55874&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=55874&r=support Expected behavior: https://bugs.php.net/fix.php?id=55874&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=55874&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=55874&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=55874&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=55874&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=55874&r=dst IIS Stability: https://bugs.php.net/fix.php?id=55874&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=55874&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=55874&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=55874&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=55874&r=mysqlcfg
