I could reproduce the phenomenon with only 14 instructions on #Intel #GoldenCove, #RaptorCove, #RedwoodCove. It appears only with the 64b-immediate initialization of the 2nd (3rd) operand in the -1024<=imm32<=1023 range.

On #LionCove... 1/2

Unaffected #Intel cores:
#CypressCove in #RocketLake
#WillowCove in #TigerLake
#Gracemont in #AlderLake & #RaptorLake
#Crestmont in #MeteorLake
#Skymont in #ArrowLake

Affected cores:
#GoldenCove in #AlderLake
#RaptorCove in #RaptorLake
#RedwoodCove in #MeteorLake
#LionCove in #ArrowLake

Addendum: There is no port or throughput change here, 1|.5 P06 will be 3|.5 P06 (and 1|1 P1 -> 3|1 P1)
#Intel, #GoldenCove, #RaptorCove, #RedwoodCove

Of course #Intel #RedwoodCove in #MeteorLake and #GraniteRapids is also involved (it would be a surprise if it wasn't)

Great article with #Intel die shots:
- #PantherLake (4P+8E+4LPE, #CougarCove)
- #WildcatLake (2P+4LPE)
- #ClearwaterForest (24c #Darkmont)
- #GraniteRapids (44c #RedwoodCove)
- #SierraForest (152c #Crestmont)
