ccf7c042c9
Fix null pointer dereference in debug output.
...
Don't display an elaborated for loop initial assignment if elaboration
has failed. Also remove duplicated message.
2015-04-13 16:31:28 +01:00
b89c059153
Fix compiler crash on source code errors in always @* block loops.
...
The compiler was correctly detecting and reporting errors in loop
expressions and statements, but then crashing when it tried to build
the sensitivity list. Fix this by not adding a loop statement to the
netlist unless all its components have been successfully elaborated.

modport and extern tf declarations are not yet supported.

Fix for br967 - allow real value for repeat statement loop length.

Enumerations are compatible if their type definitions match.
2014-11-04 15:05:49 -08:00
0237297e93
Added pruning of case statement expressions.
...
When unsized literals are used in case item expressions, it is likely
that the calculated expression width will be larger than necessary to
unambiguously select the correct case item (particularly when using
"strict" expression elaboration). This patch adds an optimisation
step that prunes the expressions to the minimum necessary width.
2014-11-02 13:02:57 +00:00
e38b5d9fb7
Eliminate unnecessary rerun of test_width in case statement elaboration.
...
Also fix a typo in a comment.

Handle foreach array name as class property.
2014-09-04 20:52:51 -07:00
3b0dfaadba
Some support for unpacked arrays in class properties.
2014-09-02 09:23:54 -07:00
dec4cd5071
Handle arrays of class objects.
...
This goes all the way down to the vvp level, where we create support
for arrays of objects, generate the new code in the -tvvp code
generator, and elaborate the arrays in the first place.
2014-08-30 10:18:57 -07:00
0cd6fbaf41
foreach loops around static arrays
...
Arrays with static dimensions can be handled specially.
This also allows for arbitrary numbers of dimensions.
2014-08-30 10:18:57 -07:00
9fa764285a
foreach multiple indices through the pform.
2014-08-30 10:18:57 -07:00
c24c26725e
A method call needs to ignore a single NULL argument from the parser
...
The parser always passes a single NULL argument for system tasks. For a
method call which will add a signal to call the method on we need to
ignore this NULL argument.
2014-08-25 18:06:08 -07:00
f602ae84ab
Elaborate foreach loops as synthetic for loops.
...
Create an implicit scope to hold the index variable, and
generate a for loop to perform the functionality of the
foreach.
2014-08-21 16:44:46 -07:00
e8b8fcba57
Support declaring queue variables all the way to vvp.
...
Nothing actually useful happens here, but the declarations
are functional.
2014-08-21 16:44:45 -07:00
0611135758
Some more cppcheck cleanup/updates
2014-06-29 20:39:40 -07:00
d05abf5ca4
Fix for GitHub issue 26 - compiler crash when module port has no internal net.
...
The compiler correctly reports an error when a module port has no
associated internal net/reg, but could crash when the module was
instantiated.
2014-05-23 22:36:28 +01:00
be0c61051d
Add synthesis of for-loops
...
This required keeping for-loops as actual things through the
netlist form so that the synthesizer can get at and understand
the parts of the for-loop. This may improve vvp code generation
in the future, but for now continue to present to the vvp code
generation the block-while form.
2014-05-08 15:05:08 -07:00
e55e832ea0
Handle unpacked arrays as output ports.
2014-04-06 08:40:09 -07:00

Handle unpacked arrays as module input ports.
2014-04-06 08:40:09 -07:00

First pass at support for continuous assign of unpacked net arrays.
2014-04-06 08:40:09 -07:00

Changs "initilzers" in a string visible with debug_elaborate.
Includes a few British->American changes in the root directory only.

Mostly comments.
One user-visible string ("Evalutated to ") changed in the debug_eval_tree case.

Elaborate r-vlaue packed struct members pads as needed.

Handle enumeration literals that are in $root.
2014-01-11 19:19:14 -08:00
68d83383ff
Elaborate nested l-values.
...
This gets nested l-values to (but just short of) the ivl_target API.
Now the elaborator can process nested l-values, but I haven't figured
out how to present that at the ivl_target.h API.
2013-11-16 16:27:05 -08:00
f16fd03dab
Elaborate PChainConstructor calls.
...
It is better to leave the handling of PChainConstructor calls to
the elaboration, instead of stripping them out early. This allows
for handling the arguments of the chain constructor in the correct
scope.

Parse/elaborate some array-patterns down to the ivl_target API.
2013-10-19 15:34:14 -07:00
18c338ad09
Handle array assignment patters through pform.
...
This gets us to elaboration. In the process also fix up ivl_type_t
type comparisons to do deep type comparison.
2013-10-19 15:34:14 -07:00
c64b8900ca
Add support for disable fork to the compiler.
