osaca_version: 0.6.1
isa: riscv
# Contains all operand-irregular instruction forms OSACA supports for RISC-V.
# Operand-regular for a RISC-V instruction form with N operands in the shape of
# mnemonic op1 ... opN
# means that op1 is the only destination operand and op2 to op(N) are source operands.
# For vector instructions with suffixes (.v, .vv, .vf), the operand behavior follows
# the base instruction pattern.
