astgen now generates ASTGEN_SUPER_* macros, instead of expanding the
ASTGEN_SUPER itself. This means that V3AstNodes.h itself can be included
in V3Ast.h, which helps IDEs (namely CLion) find definitions in
V3AstNodes.h a lot better. Albeit this is a little bit more boilerplate,
writing constructors of Ast nodes should be a lot rarer than trying to
find their definitions, so hopefully this is an improvement overall.
astgen will error if the developer calls the wrong superclass
constructor.
Rework Ast hashing to be stable
Eliminated reliance on pointer values in AstNode hashes in order to make
them stable. This requires moving the sameHash functions into a visitor,
as nodes pointed to via members (and not child nodes) need to be hashed
themselves.
The hashes are now stable (as far as I could test them), and the impact
on verilation time is small enough not to be reliably measurable.
- Remove dead code
- Simplify what is left
- Minor improvements using C++11
- Remove special case AstNode constructors used only in one place in
V3Combine (inlined instead).
This seems to belong there, eliminates some code duplication in V3Clock,
and also enables splitting AstAlwaysPost statements into different
functions in V3Order, but should otherwise have little effect.
* Add a test for hierarchical verilation without timescale
* Emit timeunit in hierarchical wrapper only when it is specified in the input design or command line option.
* Update src/V3AstNodes.h

* Add tests for unpacked array in DPI-C
* Add more generic parameter generator to AstNodes
* Supports multi dimensional array in DPI ( DPI argmuments <=> Verilator internal type conversion)
consider typedef in V3Task
fix export test
fix inout for scalar
support export func of time
* V3Premit does not show an error for wide words nor ArraySel
* Unnecessary pack func for unapcked array does not appear anymore
* Support unpacked array in runtime header
- Add an overload for lvalue VL_CVT_PACK_STR_NN
- Allow conversion from void *
* touch up tests for codacy advices
* resolve free functions. no functional change intended.
