Title: Retired FP Operations
Category: Instruction Execution Events
IAR/DAR/OPC: Y/N/N
Event Code: 0x09
Max. Inc/Cyc: 4 Definition: Provides information on number of retired floating point operations, excluding all predicated off instructions. This is a weighted sum of basic floating point operations. To count how often specific opcodes are retired, use IA64_TAGGED_INST_RETIRED.

Note

The following weights are used:
Counted as 4 ops: fpma, fpms, and fpnma
Counted as 2 ops: fpma, fpnma (f2=f0), fma, fms, fnma, fprcpa, fprsqrta, fpmpy, fpmax, fpamin, fpamax, fpcmp, fpcvt
Counted as 1 op: fms, fma, fnma (f2=f0 or f4=f1), fmpy, fadd, fsub, frcpa, frsqrta, fmin, fmax, famin, famax, fpmin, fcvt.fx, fcmp
