|
DV - Divider pipe (on port 0)
|
|
D - Data fetch pipe (on ports 2 and 3)
|
|
F - Macro Fusion with the previous instruction occurred
|
|
* - instruction micro-ops not bound to a port
|
|
^ - Micro Fusion occurred
|
|
# - ESP Tracking sync uop was issued
|
|
@ - SSE instruction followed an AVX256/AVX512 instruction, dozens of cycles penalty is expected
|
|
X - instruction not supported, was not accounted in Analysis
