- allow ICARUS_VPI_CONST to be pre-defined by the user
- use it for sizetf as well as for compiletf and calltf
- fix remaining warnings when it is defined as 'const'
Some of the last changes I added to the enumeration next()/prev() code
introduced a memory leak under some situations. This patch fixes the
leak by freeing the iterator before the new one is created.
Add an implementation for the enumeration name() method. This currently
only works if the context defines the return width (e.g. the result is
assigned to a variable). It does not work in a self-determined context
(e.g. as an argument to a system function or in a comparison). This is
a limitation in the compiler/code generator/run time not the method
implementation provided here. We may need full string support to make
this work 100%.
The standard defines how to calculate the name for an access function
or iterator if one is not given. It is supposed to be vpi followed by
the words in the name with each word capitalized. For the one to many
(iterator) interface from the enumeration typespec to the individual
constants this is vpiEnumConst not vpiMember.
Rework the actual next() and prev() methods to correctly process the
numeric count argument. Also rework the compiletf routine to give better
error messages and combine the call routine for the two methods.
Add a compiletf routine that checks the arguments and then report that
the name() method is not currently implemented.
Create the v2009.vpi module to include SystemVerilog core
functions, and start out with some of the enum methods.
Add to vvp support for creating enum types, including some
vpi access methods.
