Bug description:Linking fails when trying to use atomic_add_int and
membar_producer
Description:
------------
I'm trying to build PHP 5.4.21 on my Solaris 10 SPARC box, but it's
failing when it tries to link in atomic_add_int and membar_producer.
Both of those functions are used in ext/standard/php_crypt_r.c:
80 void _crypt_extended_init_r(void)
81 {
82 #ifdef PHP_WIN32
83 LONG volatile initialized = 0;
84 #elif defined(HAVE_ATOMIC_H) /* Solaris 10 defines atomic API within
*/
85 volatile unsigned int initialized = 0;
86 #else
87 static volatile sig_atomic_t initialized = 0;
88 #endif
89
90 #ifdef ZTS
91 tsrm_mutex_lock(php_crypt_extended_init_lock);
92 #endif
93
94 if (!initialized) {
95 #ifdef PHP_WIN32
96 InterlockedIncrement(&initialized);
97 #elif defined(HAVE_SYNC_FETCH_AND_ADD)
98 __sync_fetch_and_add(&initialized, 1);
99 #elif defined(HAVE_ATOMIC_H) /* Solaris 10 defines atomic API within
*/
100 membar_producer();
101 atomic_add_int(&initialized, 1);
102 #endif
103 _crypt_extended_init();
104 }
105 #ifdef ZTS
106 tsrm_mutex_unlock(php_crypt_extended_init_lock);
107 #endif
108 }
On my version of glibc, atomic_add_int() and membar_producer aren't
defined.
$ nm -g /lib/libc.so.1 | grep atomic_add_int
$ nm -g /lib/libc.so.1 | grep membar_producer
