Bug #: 52190
Summary: question about atomic intrinsics -- test and
documentation vary -- please clarify
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
AssignedTo: [email protected]
ReportedBy: [email protected]
This url http://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html
shows these 2 intrinsics declared like this:
Built-in Function: bool __atomic_always_lock_free (size_t size)
Built-in Function: bool __atomic_is_lock_free (size_t size)
But there are test cases for these 2 functions that have 2nd argument
(memmodel) e.g. atomic-lockfree.c lines 23 and 24
r1 = __atomic_always_lock_free (sizeof(char), 0);
r2 = __atomic_is_lock_free (sizeof(char), 0);
Please clarify, thanks!
