TotalView supports pending breakpoints, useful when setting a breakpoint on code contained in a library that has not yet been loaded into memory.

A pending action point is a breakpoint, barrierpoint, or eval point created with a breakpoint expression that does not yet correspond to any executable code. For example, a common use case is to create a pending function breakpoint with a breakpoint expression that matches the name of a function that will be loaded at runtime via dlopen(), CUDA kernel launch, or anything that dynamically loads executable code.

All four types of breakpoints can be pending (this includes line, function, methods in a class, and virtual function breakpoints). Further, a breakpoint may transition between pending to non-pending as image files are loaded, breakpoint expressions are reevaluated, address blocks are added, and invalid address blocks are nullified.
