This gets us to elaboration. In the process also fix up ivl_type_t
type comparisons to do deep type comparison.

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.
2013-07-02 20:16:47 -07:00
4ef3ac5ca6
Implement const properties of classes.
...
This implementation works by detecting assignments
to constant properties in elaboration. Allow initializer
assignments to assign to the constant, error all other
assignments, and otherwise treat the constant like any
other property.

26dc6d68cd
Handle out-of range and undefined LHS word indices in assignments.
...
For constant word indices, issue a warning if the index is out of
range or an undefined value. In any case, the RHS value should be
discarded, and the actual assignment should be skipped.
2013-05-18 19:21:37 +01:00
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.

vlog95: add support for emitting logic pull devices in a CA
...
If a logical pull device is converted into a CA then it is an assignment
with strength, so just emit the appropriate constant to get the correct
functionality (e.g. 1'b1 for a pull up and 1'b0 for a pull down).
Also add missing file/line information.

interface.

Further support for constant functions.
...
Add support for case, forever, and repeat statements in constant
functions. Also fix a bug in the constant function implementation
of NetESelect when used for zero/sign extension.
2013-04-07 19:13:30 +01:00
6da71fdf56
Fix type/width for case and case item expressions.
...
The compiler was treating case and case item expressions as
self-determined. They should be context-sensitive, just like
the operands of a comparison operation.

d0f2a9e961
Elaborate task methods as tasks with this arguments.
...
Generate the code to treat "this" as a hidden argument and have
elaborate assign to that argument.
2013-03-24 15:12:35 -07:00
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.
The "this"

1bcd3a97ad
Support disable statements and system task calls in constant functions.
...
This patch implements the evaluate_function method for the NetDisable
and NetSTask classes. It also makes the checks for a function being
constant work when the function contains nested scopes (named blocks).
2013-03-24 14:42:59 -07:00
6da610fe1e
Fix implicit casts in assignments (part 5).
...
This patch removes some code that has been made redundant by the
more general handling of implicit casts.
2013-03-24 13:51:02 -07:00
bc2a4c01c9
Fix implicit casts in assignments (part 2).
...
This patch adds support for implicit casts in module port connections
and in user task output assignments.
2013-03-24 10:17:17 -07:00
60cb78e4ab
Add packages and their own scope.
...
This makes <pkg>::<name> work properly, and also makes the
package descriptions available through VPI.

A concatenation may also need a BUFZ to hold the drive strength
...
Just like a select a concatenation needs a BUFZ to hold the drive strength.

Report in SV that Icarus cannot currently call a function like a task.
...
SystemVerilog allows a function to be called without an assignment for
the return value. This patch adds a warning that Icarus does not currently
support this and provides a place to add this functionality later.

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.

Handle DARRAYs of real variables
...
This involves working out the code to get the base type of a select
expression of a darray. Also added the runtime support for darrays
with real value elements.
2012-10-14 17:16:47 -07:00

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.

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.
