This is a major rework on the sys_fileio routines. They now have
improved compiletf routines and the calltf routines are now
standardized. Along the way a few bug were fixed as well. Some
updates to other vpi files as well.
I changed the order of the $fputc() arguments to match C and the
rest of the system functions like it ($fungetc, etc.). I recently
fixed $fungetc() so I'm assuming the $fputc() needs the same fix.
It's an Icarus specific function.
This patch cleans up some of the code to use common compiletf
routines where appropriate. It also adds code to print the
number of extra arguments and cleans up the messages a bit.
This patch adds $simparam and $simparam$str from Verilog-A.
The analog simulator parameters return 0.0 or N/A. The
vvp_cpu_wordsize system function has been moved into the
$simparam call and is now named CPUWordSize.
This patch also starts the factoring of common code in the
vpi directory. Some routines were renamed.
The priv.c file was renamed to sys_priv.c to match the
include file.
System functions can now have strings put to their output.
