Functions

Name	Description
`buildClosure(fd, irs)`	Closures are implemented by taking the local variables that need to survive the scope of the function, and copying them into a gc allocated chuck of memory. That chunk, called the closure here, is inserted into the linked list of stack frames instead of the usual stack frame.
`getEthis(loc, irs, fd)`	Return elem that evaluates to the static frame pointer for function fd. If fd is a member function, the returned expression will compute the value of fd's 'this' variable. This routine is critical for implementing nested functions.
`incUsageElem(irs, loc)`	Produce elem which increments the usage count for a particular line. Sets corresponding bit in bitmap `m.covb[linnum]`. Used to implement -cov switch (coverage analysis).
`intrinsic_op(fd)`	Convert intrinsic function to operator. Returns that operator, -1 if not an intrinsic function.
`resolveLengthVar(lengthVar, pe, t1)`	Given an expression e that is an array, determine and set the 'length' variable.
`retStyle(tf)`	Determine return style of function - whether in registers or through a hidden pointer to the caller's stack.
`setClosureVarOffset(fd)`	Go through the variables in function fd that are to be allocated in a closure, and set the .offset fields for those variables to their positions relative to the start of the closure instance. Also turns off nrvo for closure variables.
`setEthis(loc, irs, ey, ad)`	Initialize the hidden aggregate member, vthis, with the context pointer.
