+export const description = `
+'workgroupBarrier' affects memory and atomic operations in the workgroup address space.
+
+All synchronization functions execute a control barrier with Acquire/Release memory ordering.
+That is, all synchronization functions, and affected memory and atomic operations are ordered
+in program order relative to the synchronization function. Additionally, the affected memory
+and atomic operations program-ordered before the synchronization function must be visible to
+all other threads in the workgroup before any affected memory or atomic operation program-ordered
+after the synchronization function is executed by a member of the workgroup. All synchronization
+functions use the Workgroup memory scope. All synchronization functions have a Workgroup
+execution scope.
+
+All synchronization functions must only be used in the compute shader stage.
