Adds a new command "record btrace pt" to configure the kernel to use Intel(R) Processor Trace instead of Branch Trace Strore. The "record btrace" command chooses the tracing format automatically. Intel(R) Processor Trace support requires Linux 4.1 and libipt. gdb/ * NEWS: Announce new commands "record btrace pt" and "record pt".
