Abstract
Embodiments of the present invention are directed to a computer-implemented method for generating and verifying hardware instruction traces including memory data contents. The method includes initiating an in-memory trace (IMT) data capture for a processor, the IMT data being an instruction trace collected while instructions flow through an execution pipeline of the processor. The method further includes capturing contents of architected registers of the processor by: storing the contents of the architected registers to a predetermined memory location, and causing a load-store unit (LSU) to read contents of the predetermined memory location.
