[Iverilog-devel] Icarus keys in the Windows registry

[Martin W. <mai...@ma...>]

When running natively in Windows, iverilog-vpi stores a couple of keys in the 
registry. Currently it stores these in

   HKEY_LOCAL_MACHINE\Software\Icarus Verilog

With typical Microsoft consistency, a 32-bit application running with normal 
user privileges can add these keys to the registry, but, on the same Windows 
machine, a 64-bit application must be running with administrator privileges.

Currently iverilog-vpi silently fails to store the keys when built as a 64-bit 
application. I could fix this in two ways:

   - output a warning message to inform the user they need to run with
     administrator privileges

   - change the key location to HKEY_CURRENT_USER

I'm inclined to go for the second option. Does anyone wish to argue otherwise?
