1. A method, comprising: determining whether a sync point is to be generated concurrent with an encountering of a branch instruction, wherein the sync point comprises a packet of information that is transmitted by a target system to a host computer and causes the host computer to synchronize trace streams; and generating said sync point to include a value stored in a program counter at the time the sync point is generated and to indicate that the sync point occurred concurrent with the encountering of a branch instruction, wherein said generating comprises causing a single bit in the sync point to indicate that said program counter value represents a target address of a branch instruction.
