Module dmd.toir

Compiler implementation of the D programming language.




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, 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.
