* Fix memory leak of t_trace_cat and t_trace_cat_renew
* Fix memory leak of t_trace_c_api
* Fix memory leak in t_trace_public_func and t_trace_public_func_vlt
* Fix memory leaks in t_flat_build (and probably more).
* Use unique_ptr in testcases
* Guarantee mechanism to initialize just once is now in VerilatedInitializer. No functional change is intended.
* Make sure to initialize Verilated::NonInitialized just once. Fixes
memory leak in t_prot_lib_shared and t_hier_block_prot_lib_shared.
* Call setup() and teardown() of Verilated::NonSerialized.
* Test that indexing into memory word fails
* VPI: don't index into memory word
Memory and memory words share a VerilatedVar, so check for memory word before attempting to index.
* Test that range iterator exhausts after 1 dimension
* Separate range iterator from range object
Range iterators should return NULL after all ranges have been returned
The end iterator always points to an element past the end of the list.
When new elements are added to the back of the list, they are inserted
before the end iterator.
Instead, track the last element in the list at the start of processing
and stop after it's been processed.
Previously, in any given VPI callback, if the callback body registered
the same callback, that registering would be processed in the currently
executing call to the call*Cbs function. In the worse case, this could
lead to an infinite loop.
* Add a test to use string for $fgets
* Use dedicated function for $fgets to std::string
* share the implementation of $fgets
* Pass -1 for bitwidth of std::string to distinguish from POD
* add checks for scanf with string
* apply clang-format
This is to allow C++ verilator toplevel to support
multiple modes of waveform tracing
VM_TRACE_FST can be used inside a #if VM_TRACE
section to switch between classic .vcd tracing and the
more compact .fst format supported by GTKWAVE
