assembleCall

Function: assembleCall { function asm -> }

The assembleCall prim is the workhorse assembler call used to assemble all vanilla instructions -- those which don't have an associated label or other similar peculiarity.

Note in particular that the assembleCall prim is used to deposit calls to both functions coded in-db, and also primitive functions coded in-server in C: The Muq compiler writer has in general no need to distinguish between these two cases, and Muq compilers have in general no need to contain a list of all primitives supported by the Muq virtual machine. (This both simplifies the Muq compilers, and means that they do not need to be recoded if a given function changes from being a C-coded prim to being coded in-db.)

The function argument may be either a compiledFunction, or else a symbol containing a compiledFunction in its symbolFunction slot (symbol$s.function).

For example, here's a hand-assembly of the function : x * ;

makeAssembler --> *asm*
stack:
*asm* reset
stack:
#'* *asm* assembleCall
stack:
nil -1 makeFunction *asm* finishAssembly --> #'x ( Compile fn 'x' )
stack:
2.3 3.4 x ( Invoke function )
stack: 7.81982
