Bug #: 54005
Summary: Use __atomic_always_lock_free in libstdc++
is_lock_free instead of __atomic_is_lock_free
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Depends on: 54004
According to http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2992.htm,
the is_lock_free property goes for all instances of a given type. So,
libstdc++ should use __atomic_always_lock_free instead of __atomic_is_lock_free
as it does now, at r189499, libstdc++-v3/include/bits/atomic_base.h. But
first, better fix the depended bugs.
