Purpose

Provide implementations of atomic operations for X86_64/GCC.

Classes

• bsls::AtomicOperations_X64_ALL_GCC: implementation of atomics for X86_64/GCC

Description

This component provides classes necessary to implement atomics on the Linux X86_64 platform with GCC. The classes are for private use only. See bsls_atomicoperations and bsls_atomic for the public interface to atomics.

Notes

• GCC atomic intrinsics are used where possible instead of the assembly code,
• "+m" constraint may cause an inconsistent operand constraint error in GCC 3.x in optimized builds, therefore sometimes a combination of output "=m" and input "m" constraints is used.
