Edit report at https://bugs.php.net/bug.php?id=69896&edit=1 ID: 69896 User updated by: fh-phpbugs at fholzhauer dot de Reported by: fh-phpbugs at fholzhauer dot de Summary: zend_operators.h:685:2: error: 'asm' operand has impossible constraints Status: Closed Type: Bug Package: Compile Failure Operating System: Ubuntu Linux - Trusty 14.04.1 PHP Version: 7.0.0beta2 Assigned To: ab Block user comment: N Private report: N New Comment: I can also confirm that the new patch fixes the problem for me. Previous Comments: ------------------------------------------------------------------------ [2015-08-02 15:32:58] ab@php.net @clicky, hm, I don't reproduce it, fetched a fresh stretch iso just now. Tried with your description in #69765 as well. Another way to keep asm for 4.8 could be maybe removing --with-layout=GNU, as I've observed. But either way, no issue with gcc 4.9 for me. Ondrej, can you check as well please? Thanks. ------------------------------------------------------------------------ [2015-08-02 11:02:37] clicky at erebot dot net The build is still broken for me on Debian Stretch 64 bits (gcc version 4.9.2 (Debian 4.9.2-10)). Using the attached patch did not fix the issue (obviously, since the patch is specifically targetted towards GCC 4.8.x). It only triggers when building a 32 bits version of PHP. ------------------------------------------------------------------------ [2015-08-02 07:50:18] ab@php.net Thanks for the checks, Remi. So the part is broken at least in two distros. Probably fair enough to disable for all i386 gcc-4.8 as no guarantee what happens elsewhere. Thanks. ------------------------------------------------------------------------ [2015-08-02 07:31:37] ab@php.net Automatic comment on behalf of ab Revision: http://git.php.net/?p=php-src.git;a=commit;h=ee2e1691080dad2a3110107dd8bd02ee23b41fa0 Log: Fixed bug #69896 'asm' operand has impossible constraints ------------------------------------------------------------------------ [2015-08-02 06:11:10] remi@php.net I didn't encounter this issue, mostly because I don't have any gcc 4.8 / 32bits target ;) Fedora use gcc 4.9 or 5.1 RHEL 6 use gcc 4.4 RHEL 7 use gcc 4.8 but is 64bits only. So I run some test builds Fedora 18 (gcc 4.7.2): build ok Fedora 20 (gcc 4.8.3): same error, fixed by the proposed patch ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
