Rework the heirarchical identifier parse syntax and pform to handle more general combinations of heirarch and bit selects.
2007-05-24 06:07:11 +02:00
/*
Handle indexed defparams. The l-value of a defparam assignment is a hierarchical name that may include array selects to select scopes from module arrays. Therefore it makes no sense to store parsed defparams in a map. Instead, they should go into an ordered list. This also maked more sense because later defparams *may* have the same name as a previous defparam, and will override the previous defparam. So replace the map of parsed defparams with a list of parsed defparams. Also, as soon as the defparam expression is elaborated, the list entry is no longer needed, so delete it. Save memory.

Parse simple typedefs Parse typedefs with structs and enums, but give a sorry message, because they are not yet supported. Rearrange some of the parse rules for variables in order to increase comonality with the typedef rules.

First pass at getting strings to work. In vvp, create the .var/str variable for representing strings, and handle strings in the $display system task. Add to vvp threads the concept of a stack of strings. This is going to be how complex objects are to me handled in the future: forth-like operation stacks. Also add the first two instructions to minimally get strings to work. In the parser, handle the variable declaration and make it available to the ivl_target.h code generator. The vvp code generator can use this information to generate the code for new vvp support.

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.
