assignment.

Larry Doolittle 8ea3b6b0b8 header includes for gcc-4.3 compatibility
minimal changes required to build without error
tested with gcc-4.3 (Debian 4.3-20071130-1) 4.3.0 20071130 (experimental)
2008-01-04 16:14:44 -08:00
Stephen Williams 7975e14b5c LineInfo uses perm_string for path.
Rework the handling of file names to use a perm_string heap to hold
the file names, instead of the custom file name heap in the lexor.
Also rename the get_line to get_fileline to reflect its real duties.
This latter chage touched a lot of files.

steve 91d84e7dc7 Major rework of array handling. Memories are replaced with the
more general concept of arrays. The NetMemory and NetEMemory
 classes are removed from the ivl core program, and the IVL_LPM_RAM
 lpm type is removed from the ivl_target API.

steve b1fd927acb Named events really should be expressed with PEIdent
objects in the pform,

 Handle named events within the mix of net events
 and edges. As a unified lot they get caught together.
 wait statements are broken into more complex statements
 that include a conditional.

 Do not generate NetPEvent or NetNEvent objects in
 elaboration. NetEvent, NetEvWait and NetEvProbe
 take over those functions in the netlist.

steve e7efc2709a Redesign the implementation of scopes and parameters.
I now generate the scopes and notice the parameters
 in a separate pass over the pform. Once the scopes
 are generated, I can process overrides and evalutate
 paremeters before elaboration begins.

Thanks to Larry Doolittle <LRDoolittle@lbl.gov>.
