1 9.15.11 AMD's Lightweight Profiling Instructions
1 ------------------------------------------------
1 
1 'as' supports AMD's Lightweight Profiling (LWP) instruction set,
1 available on AMD's Family 15h (Orochi) processors.
1 
1    LWP enables applications to collect and manage performance data, and
1 react to performance events.  The collection of performance data
1 requires no context switches.  LWP runs in the context of a thread and
1 so several counters can be used independently across multiple threads.
1 LWP can be used in both 64-bit and legacy 32-bit modes.

1 Lightweight Profiling Specification' available at Lightweight Profiling
