The general purpose unconditional abstract call operations you will be using when writing general assembly code. Depending on the number and order of arguments and the number of return values the assembler will pick the most dense from a myriad of different encodings. This can result in gangs or it can be a short single operation.
call(lit n, p target, args args) → ops r0 ...
An indirect call to a dynamically computed address.
encoding:
call(lit n, p target, off argv, count argc)
encoding:
call(lit n, p target, off argv, count argc, lit argv)
alternate encoding: call0, call1, calln,

call(lit n, lbl target, args args) → ops r0 ...
Function is known at compile time.
