Req #69928 [NEW]: -ffast-math incompatible with sqlite extension

From: 191919 at gmail dot com Operating system: OS X PHP version: 7.0Git-2015-06-25 (Git) Package: Compile Failure Bug Type: Feature/Change Request Bug description:-ffast-math incompatible with sqlite extension Description: ------------ -ffast-math brings performance increase and the precision can be accepted in most cases, but php cannot be compiled with this directive. Would you please consider to add an extra ./configure setting to skip the check in sqlite3 extension as it is the only one that explicitly refuses the -ffast-math flag? Test script: --------------- CC=/opt/bin/gcc CFLAGS="-O2 -msse4.2 -ffast-math -fomit-frame-pointer -fno-stack-protector -fno-exceptions" ./configure --prefix=/opt/php7 --enable-opcache Expected result: ---------------- Compilation succeeds. Actual result: -------------- gcc-5.1.0 gave: /Users/xx/box/php-src/ext/sqlite3/libsqlite/sqlite3.c:23512:3: error: #error SQLite will not work correctly with the -ffast-math option of GCC. # error SQLite will not work correctly with the -ffast-math option of GCC. ^ -- Edit bug report at https://bugs.php.net/bug.php?id=69928&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69928&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69928&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69928&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69928&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69928&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69928&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69928&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69928&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69928&r=support Expected behavior: https://bugs.php.net/fix.php?id=69928&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69928&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69928&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69928&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69928&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69928&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69928&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69928&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69928&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69928&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69928&r=mysqlcfg
