Bug #: 55233
Summary: libstdc++ atomic does not support hle_acquire/release
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]
Target: x86_64-linux
The underlying __atomic_* C intrinsics support TSX HLE ACQUIRE/RELEASE, but
libstdc++ atomic does not define the enum values or mask the bits.
However extending the libstdc++ enum may run into a variant of PR55139
