+/// This file implements the instruction info view.
+///
+/// The goal fo the instruction info view is to print the latency and reciprocal
+/// throughput information for every instruction in the input sequence.
+/// This section also reports extra information related to the number of micro
+/// opcodes, and opcode properties (i.e. 'MayLoad', 'MayStore', 'HasSideEffects)
+///
+/// Example:
+///
+/// Instruction Info:
+/// [1]: #uOps
+/// [2]: Latency
+/// [3]: RThroughput
+/// [4]: MayLoad
+/// [5]: MayStore
+/// [6]: HasSideEffects
+///
+/// [1] [2] [3] [4] [5] [6] Instructions:
+/// 1 2 1.00 vmulps %xmm0, %xmm1, %xmm2
+/// 1 3 1.00 vhaddps %xmm2, %xmm2, %xmm3
+/// 1 3 1.00 vhaddps %xmm3, %xmm3, %xmm4
