Add a new type BlockCall that represents the pair of a block name with arguments to be passed to it. (The mnemonic here is that it looks a bit like a function call.) Rework the implementation of jump, brz, and brnz to use BlockCall instead of storing the block arguments as varargs in the instruction's ValueList. To ensure that we're processing block arguments from BlockCall values in instructions, three new functions have been introduced on DataFlowGraph that both sets of arguments: inst_values - returns an iterator that traverses values in the instruction and block arguments map_inst_values - applies a function to each value in the instruction and block arguments overwrite_inst_values - overwrite all values in an instruction and block arguments with values from the iterator Co-authored-by: Jamey Sharp <jamey@minilop.net>
This crate provides an interpreter for Cranelift IR. It is still a work in progress, as many instructions are unimplemented and various implementation gaps exist. Use at your own risk.
