Returns

InstructionFlags

Connected()

Called after the ILInstruction was connected to the root node of the ILAst.

protected override void Connected()

Disconnected()

Called after the ILInstruction was disconnected from the root node of the ILAst.

Parameters

deleteUnreachableBlocks bool

If true, unreachable blocks are not included in the new order.

Returns

List<Block>

WriteTo(ITextOutput, ILAstWritingOptions)
