Add properties to the classes, and elaborate expressions that
have class properties. Describe class object property references
all the way down to the stub target.
The compiler doesn't currently check that the width of an indexed
part select is non-zero. If code contains this erroneous case, the
compiler can crash (with an assertion failure). This patch causes
the compiler to output a suitable error message and recover. It
also fixes a potential crash if an illegal expresson is encountered.
Implement through the ivl core to the ivl_target.h API.
Also draft implementation of creating and storing arrays
in the vvp runtime and code generator.
This patch extends the compiler to support all specparam declarations
allowed by the 1364-2005 standard. For compatibility with other
simulators, it allows specparam values to be used in any constant
expression, but outputs a warning message and disables run-time
annotation of a specparam if it is used in an expression that must
be evaluated at compile time.
This handles a few cases where the non-constant bit selects are
in the final index. This doesn't handle all the cases of packed
arrays, but it handles some common cases.
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%.
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.
Add code to allow an enumeration method to be called as a function.
This is only the compiler support. The runtime support is still missing
so only an empty argument call will succeed (e.g. next(), etc.). For now
the rest get a warning message.
This patch fixes a few more bugs in the enumeration code.
It add support for saving the file and line information to make
diagnostic messages better.
It updates some of the compiler warning messages to use the file
and line information.
It passes if the enumeration type is signed all the way to the
code generators.
It fixes the parser to correctly have the range after the signed
designation for the vector types.
It adds a warning that vvp does not currently support a negative
two state enumeration value.
