Stephen Williams 16414f921f Handle default arguments in class new functions. 2013-09-20 20:44:56 -07:00
Stephen Williams 9a116498a2 Handle task/function default expressions in parsing/pform.
This gets it to (but not through) the elaborator.

Stephen Williams 5326790932 Add support for class static properties.
Static properties are like variables in a named scope.
Detect these variables during elaboration so that the
code generator just sees them as variables.

Stephen Williams 75b4b94061 Elaborate implicit initializers
Remaining pform fixup of property initializers, and
elaboration and code generation for implicit constructor.
2013-07-02 20:16:46 -07:00
Stephen Williams af304fea65 Fix repeated use of disabled const functions.
If constant functions are exited by a return/disable, fix
the leaked "disable" flag that causes blocks in the next
try at the function to not work.

There are also a lot of debug messages added to help find
this and similar problems.

Stephen Williams 8994ef1483 Implement class constructors.
Class constructors are the "new" method in a class description.
Elaborate the constructor as an ordinary method, but the only
way to access this method is to implicitly call it. The elaborator
will take the constructor call and generate a naked "new" expression
and implicit constructor method call with the object itself as the
return value.

Stephen Williams 20ee350601 Generalize user defined function return type handling.
I'm gonna need functions to return class objects, so generalize
the output types of user defined functions.

Stephen Williams 44cd9158e8 Elaborate parameters, tasks and functions in packages.

interface.

Stephen Williams 17330a3073 Elaborate class task and function methods.
The parse of class methods already works, this patch forms
the methods into their own scopes, and elaborates those scopes.

Stephen Williams 77d24cd095 Elaborate class_new and (null) expressions
This gets the types right for class_new and null expressions, and
elaborate them down to the ivl_target.h API.
2012-12-10 19:13:43 -08:00
Stephen Williams 914ebeca4a Some rework to allow for nested packed types.
This also simplifies the NetNet set of contructors and generalizes
the types that are supported, especially packed types.

Arun Persaud f5aafc32f9 updated FSF-address 2012-08-29 10:12:10 -07:00
Cary R 0faaa79bae Remove two duplicate typedef statements.
These two typedefs exactly matched earlier ones in the same scope and
gcc was complaining that they were shadowing the previous definitions.
Since the definitions matched exactly just deleting the second
typedef was acceptable.

Stephen Williams fdc92ea464 Elaborate dynamic array expressions (lval/rval) down to ivl_target.h 2012-07-22 10:52:07 -07:00
Stephen Williams 14f229de30 Parse support for dynamic arrays.
This includes limited support for dynamic arrays down to the code
generator, and some stubs in the vvp code generator and vvp run time.

Stephen Williams 78b0b49a4e Support struct members that are packed arrays. 2012-05-22 17:31:25 -07:00
Stephen Williams 69c10c4722 Handle case generate under a conditional generate that is unnamed.
When a conditional statement is unnamed, it doesn't create a scope
and we get into "direct" generate scheme elaboration. This direct
elaboration needs to handle case generate schemes.

Stephen Williams 13348ba7ac Ranges are ranges, not expression lists.
This is a cleanup in preparation for better support of range lists.

Stephen Williams 3e4f8b625f Get packed signals working through to simulation in some situations.
When dynamic indexing of early dimensions is not needed, we can get
pretty far with getting packed arrays to work.

Stephen Williams 3a2866b57c Handle members of packed struct as implicit part selects.
Packed struct members are synonymous with part selects, but in a
much more convenient form, so get them to work that way.

Cary R 4006bb2336 Some more cppcheck cleanup.
This patch cleans up most of the warnings in the main (ivl) directory.

Martin Whitaker 1e9f9685cc First step towards supporting constant user functions.
This patch allows the compiler to perform early elaboration
of functions if they are encountered in expressions that are
elaborated before the function would normally be elaborated.
This makes the function available for constant evaluation.
Suitable error messages are generated if a function that is
used in a constant expression is not a valid constant function.

Martin Whitaker 93067149f1 Rework of constant expression error reporting.
This patch changes the method used to signal that a constant expression
is being elaborated from flags stored in global variables to flags
passed down the call chain. It also generates more informative error
messages when variable references are found in a constant expression.
