Properly implement casts from strings and dynamic arrays to vectors.
...
As discussed on iverilog-devel (2018-03-09), the existing implementation
(using Icarus-specific vpi functions) only worked with assignments to
simple variables, and could not be easily modified to work more generally.
So use the new vvp instructions added in the previous two commits.

Fix GitHub issue #244 : handle mixed signed/unsigned power operations.
...
The signed version of the power operation in vvp should only be used
if the exponent is signed. Both signed and unsigned versions will
produce the correct result regardless of the type of the base operand,
provided it has been appropriately extended to the result size.

When testing for == and ===, there is no need to also calculate <,
so it makes sense to have a special instruction for these cases.

the vec4 stack.

vvp code generator try to generate condition flags directly.
...
When generating code for a condition expression, i.e. directly
before a %jmp/X statement, try to generate the result into the
flag bit without passing through the vec4 stack. For example, the
%cmpX/X instructions generate results into the flag bits, so it
makes no sense to push these bits into the vec4 stack then pop
them back into the flag bit. So try to handle this case.
2014-11-19 18:32:19 -08:00

Add %cmpi/s and %cmpi/u instructions for performance
