Martin Whitaker 871d447ff7 Reinstate error recovery for range expressions.
If an error is found whilst elaborating a range expression in a signal
declaration, create a dummy range and continue elaboration. This stops
the compiler reporting an error every time that signal is referenced.

Cary R 4f62a0d1f2 Check enum trimmed bits for values with undefined bits
If an enumeration constant has undefined bits then we need to verify that
the bits that are trimmed match the MSB of the remaining bits.

Cary R e7df9774aa When comparing that an enumeration is in range cast the value to 2-state
When checking that an enumeration value is in range we need to cast it to
a 2-state value so that when we compare it we get a true or false value
instead of an undefined value. Undefined bits in the comparison return
undefined which is not logically false.

Martin Whitaker 7ab0824adf Fix for br961 - function return type elaborated in wrong scope.
The return type of a function should be elaborated in the context of
the enclosing scope, not in the context of the function itself.

Martin Whitaker 7fad4779c5 Add error recovery when elaboration of a type range fails.
If elaboration of the msb or lsb expression in the range of a vector
type specification failed (due to an error in the Verilog code being
compiled), an assertion failure was being triggered when the compiler
attempted to evaluate the expressions. Bypassing the evaluation (and
using a default value) should allow us to recover from the error.

all assignments to a vector property will get the size right.

Cary R c5e0507941 Fix the modpath edge and vpi_put_delay() code
The code to get the correct modpath delay for a given edge had the X and Z
entries swapped.

When putting a delay from the VPI the 2 delay to twelve delay mapping was
incorrect and the to/from X delays were also not being calculated correctly.

Maciej Suminski c55a013162 vhdlpp: Support for integer() function.
Note: I could not find any info about the integer() function, but it is
used in the VHDL standard packages (e.g. math_real, see:
http://www.csee.umbc.edu/portal/help/VHDL/packages/mathpack.vhd)
Real numbers are rounded, this is compatible with ModelSim behavior.
