Stephen Williams d1a35d5152 Handle nil queue as a was to delete a queue.
Treat this like assigning null to a dynamic array. This deletes the
queue and thus has the effect of clearing it.

Stephen Williams 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.

package imports in module headers

Stephen Williams e55e832ea0 Handle unpacked arrays as output ports. 2014-04-06 08:40:09 -07:00
Stephen Williams 6caa41cc93 First pass at support for continuous assign of unpacked net arrays. 2014-04-06 08:40:09 -07:00
Stephen Williams f8e33b12cd Clean up pform_module_define_port in preparation for new tricks.
Get rid of the data_type, signed_flag, and range arguments to the
pform_module_define_port because they add no value within the
parse.y parser. Cleaning these out will hopefully ease the addition
of new functionality.

Stephen Williams aaee9989c2 Handle for_variable_declaration
This can be handled entirely in the parser, where we rewrite the
syntax to me a begin/end block that contains the index variable
declaration and the for loop.

Martin Whitaker a3450bf856 Fixes for GitHub issues 13 and 15.
The verinum arithmetic operators now observe the standard Verilog
rules for calculating the result width if all operands are sized.
If any operand is unsized, the result is lossless, as before.
They also now all observe the standard rules for handling partially
undefined operands (if any operand bit is 'x', the entire result is
'x').

I've also added the unary '-' operator, and renamed v_not() to be
the unary '~' operator. This has allowed some simplification in
other parts of the compiler.

Martin Whitaker 8135f369a5 Fix for GitHub issue 11 : Syntax error on operator attributes.
Attributes are allowed to be attached to unary, binary, and ternary
operators in expressions. For now just accept and discard them.

Stephen Williams 52a9fdde8a Handle packed structs as module outputs. 2014-02-03 19:22:59 -08:00
Stephen Williams 49cf5556a2 Fix primitive table lexical analysis.
Sequences of digits in the table of a primitive may be matched
as decimal numbers instead of digits, and this breaks some
primitives.

Implement some yacc rules for assertion syntax.

Add the -gassertions/-gno-assertions command-line flags to
enable or disable assertions.

Stephen Williams 9f83882bcc Parse/elaborate class derivation
This gets us down to working classes, but does not yet implement
calls to the parent constructor, implicitly or explicitly.

Stephen Williams 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.

This gets it to (but not through) the elaborator.

Stephen Williams 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.

Stephen Williams cf47a759d1 Implement the "local" class member protection.
Test during elaboration that the member really is
accessible in the context where the elaboration
happens.
