Functions

Name	Description
`buildCapture(fd)`	build a debug info struct for variables captured by nested functions, but not in a closure. must be called after generating the function to fill stack offsets
`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.
`getParentClosureType(sthis, fd)`	for a nested function 'fd' return the type of the closure of an outer function or aggregate. If the function is a member function the 'this' type is expected to be stored in 'sthis.Sthis'. It is always returned if it is not a void pointer. buildClosure() must have been called on the outer function before.
`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.
`resolveLengthVar(lengthVar, pe, t1)`	Given an expression e that is an array, determine and set the 'length' variable.
`retStyle(tf, needsThis)`	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.
