@@ -104,18 +104,21 @@ The following model was developed empirically.
Assume procedure P calls procedure Q.
The call takes place in basic block B.
.DS
ZP = # zero parameters
CP = # constant parameters - ZP
LN = Loop Nesting level (0 if outside any loop)
F = \fIif\fR # formal parameters of Q > 0 \fIthen\fR 1 \fIelse\fR 0
FT = \fIif\fR Q falls through \fIthen\fR 1 \fIelse\fR 0
S = size(Q) - 1 - # inline_parameters - F
L = \fIif\fR # local variables of P > 0 \fIthen\fR 0 \fIelse\fR -1
A = CP + 2 * ZP
N = \fIif\fR LN=0 and P is never called from a loop \fIthen\fR 0 \fIelse\fR (LN+1)**2

S stands for the size increase of the program,
which is slightly less than the size of Q.
