Jaroslav Sevcik 089cfe113d Improve step over performance ... Summary: This patch improves step over performance for the case when we are stepping over a call with a next-branch-breakpoint (see https://reviews.llvm.org/D58678), and we encounter a stop during the call. Currently, this causes the thread plan to step-out //each frame// until it reaches the step-over range. This is a regression introduced by https://reviews.llvm.org/D58678 (which did improve other things!). Prior to that change, the step-over plan would always step-out just once. With this patch, if we find ourselves stopped in a deeper stack frame and we already have a next branch breakpoint, we simply return from the step-over plan's ShouldStop handler without pushing the step out plan. In my experiments this improved the time of stepping over a call that loads 12 dlls from 14s to 5s. This was in remote debugging scenario with 10ms RTT, the call in question was Vulkan initialization (vkCreateInstance), which loads various driver dlls. Loading those dlls must stop on the rendezvous breakpoint, causing the perf problem described above.
