- Rename `--dump-treei` option to `--dumpi-tree`, which itself is now a
special case of `--dumpi-<tag>` where tag can be a magic word, or a
filename
- Control dumping via static `dump*()` functions, analogous to `debug()`
- Make dumping independent of the value of `debug()` (so dumping always
works even without the debug flag)
- Add separate `--dumpi-graph` for dumping V3Graphs, which is again a
special case of `--dumpi-<tag>`
- Alias `--dump-<tag>` to `--dumpi-<tag> 3` as before
Introduce the @astgen directives parsed by astgen, currently used for
the generation child node (operand) accessors. Please see the updated
internal documentation for details.
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.
V3Hasher is responsible for computing AstNode hashes, while V3DupFinder
can be used to find duplicate trees based on hashes. Interface of
V3DupFinder simplified somewhat. No functional change intended at this
point, but hash computation might differ in minor details, this however
should have no perceivable effect on output/runtime.
Implements (#2964)
* 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 a test to use unpacked array port in hierarchical verilation and protect-lib.
* V3EmitV supports unpacked array variables
* Can Emit local unpacked array properly
* Update golden of t_debug_emitv
* Support unpacked array port in protect-lib
* Remove t_prot_lib_unpacked_bad test as unpacked array is supported now.
* 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.
* add a test for protect-lib without sequential logic that cause the follwoing error.
%Error: obj_vlt/t_prot_lib_comb/secret/secret.sv:78:14: syntax error, unexpected ')'
78 | always @() begin
| ^
* protect-lib wrapper must contain sequential signal related statements
only if the protected design is a sequential logic.
Diff looks big, but actually just add "if (m_hasClk)" condition.
