Detailed Description

MI-level Statepoint operands.

Statepoint operands take the form: <id>, <num patch="" bytes="">, <num call="" arguments>="">, <call target>="">, [call arguments...], <StackMaps::ConstantOp>, <calling convention>="">, <StackMaps::ConstantOp>, <statepoint flags>="">, <StackMaps::ConstantOp>, <num deopt="" args>="">, [deopt args...], <gc base/derived pairs...> <gc allocas...> Note that the last two sets of arguments are not currently length prefixed.
