Making the scope type NESTED_MODULE was just plain wrong, because it didn't really encapsulate the meaning of program blocks OR nested modules. So instead create nested_module() and program_block() flags and use those to test scope constraints.
The compiler currently performs parameter expression elaboration before performing parameter overrides. This means that the information needed to correctly determine the expression type and width may not be available at the time elaboration is performed. This patch reworks the code to delay elaboration until after all overrides have been performed. It also provides a new -g option that controls how the width of parameter expressions is calculated when the parameter itself is unsized.
The functions (malloc, free, etc.) that used to be provided in malloc.h are now provided in cstdlib for C++ files and stdlib.h for C files. Since we require a C99 compliant compiler it makes sense that malloc.h is no longer needed. This patch also modifies all the C++ files to use the <c...> version of the standard C header files (e.g. <cstdlib> vs <stdlib.h>). Some of the files used the C++ version and others did not. There are still a few other header changes that could be done, but this takes care of much of it.
When searching for a symbol we do not want to search up the hierarchical stack if the symbol we are searching for was prefixed with a hierarchical path.
Remove the #ident and $Log$ strings from all the header files and almost all of the C/C++ source files. I think it is better to get this done all at once, then to wait for each of the files to be touched and edited in unrelated patches.
This patch splits any VVP net functor that needs to access both statically and automatically allocated state into two sub-classes, one for handling operations on statically allocated state, the other for handling operations on automatically allocated state. This undoes the increase in run-time memory use introduced when automatic task/function support was first introduced. This patch also fixes various issues with event handling in automatic scopes. Event expressions in automatic scopes may now reference either statically or automatically allocated variables or arrays, or part selects or word selects thereof. More complex expressions (e.g. containing arithmetic or logical operators, function calls, etc.) are not currently supported. This patch introduces some error checking for language constructs that may not reference automatically allocated variables. Further error checking will follow in a subsequent patch.
to handle more general combinations of heirarch and bit selects.
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.
