Method insert_inst

cranelift/codegen/src/cursor.rs:535–542

Insert an instruction at the current position. - If pointing at an instruction, the new instruction is inserted before the current instruction. - If pointing at the bottom of a block, the new instruction is appended to the block. - Otherwise panic. In either case, the cursor is not moved, such that repeated calls to `insert_inst()` causes instructions to appear in insertion order in the block.

    /// instructions to appear in insertion order in the block.
