This patch adds the constant system functions for Verilog-2005 and Verilog-AMS. These are evaluated at compile time. $abs(), $min() and $max() support their polymorphic behavior in the compiler where it really matters. They are always evaluated as reals in the run time and the result/argument(s) will be converted as needed. The Verilog-2005 functions are available if using the 2005 generation (default) and if either the icarus-misc (also on by default) or verilog-ams flags are set. The Verilog-AMS functions are available if either the icarus-misc or verilog-ams flags are set.
