HL.CMP.EQI evaluates equality over decoded scalar operands and publishes canonical XLEN one or zero.
The instruction snapshots its operands, prepares the decoded immediate, and then evaluates equality.
A true relation becomes XLEN one; a false relation becomes XLEN zero.
RegDst selects the encoded destination or discard behavior.SrcL supplies the left scalar source.simm24 supplies a signed encoded immediate.The canonical boolean is published through the encoded destination, then TPC advances by 6 bytes.
The instruction does not modify commit state and does not access memory or reservation state.
Encoding, reserved field values, and source availability are checked before destination, control, or TPC effects.
This example illustrates the current owner and does not create a second semantic definition.
hl.cmp.eqi SrcL, simm, ->{t, u, Rd} publishes XLEN one when its condition is true and XLEN zero otherwise.
Bodies come from owning ASL. Dragging or buttons change only this page-session view order.
