#MeteorLake
Summary:
- On #Intel GDC/RWC/LNC/(SMT?)
- 64b any shift/rotate/BZHI/BEXTR except RORX
- 64b initialized read operand with -1025- 1|.5 P06 slows down to 3|1 P1?

This reminds me somewhat of SHLD, which with the same registers is 1|.5 P06, with different ones 3|1 P1

The undocumented b2h performance counter (uops execution on vector P20/21/22/23 port) in #Intel #Crestmont (even in #MeteorLake) works same way as in #Skymont, making possible direct comparison these cores.
Is this a positive side effect of having both cores in the same #ArrowLakeH product?

Of course #Intel #RedwoodCove in #MeteorLake and #GraniteRapids is also involved (it would be a surprise if it wasn't)
It is worth to mention that #Intel #LionCove and #Skymont in #ArrowLake has similar, but not totally same immediate handling (these can't handle the LEA [r64+imm8/32] cases).

In 0xC5 #Intel #ArrowLakeH, like in 06_AAh, 06_ACh, 06_B5h #MeteorLake and #ArrowLakeU, the CPUID.1Fh topology info is wrong: community.intel.com/t5/Processors/Detecting-LP-E-Cores-on-Meteor-Lake-in-software/m-p/1591719#M71595
But this time the different E/LPE #Skymont / #Crestmont saves the day:1/2
