Fix --protect-ids when using SV classes (#2994) 
A few names were incorrectly mangled, which made --protect-ids produce
invalid output when certain SV class constructs were uses. Now fixed and
added a few extra tests to catch this.

Split procedures to better respect --output-split-cfuncs (#2942) 
CFuncs only used to be split at procedure (always/initial/final block),
which on occasion can still yield huge output files if they have large
procedures. This patch make CFuncs split at statement boundaries within
procedures. This has the potential to help a lot, but still does not
help if there are huge statements within procedures.

Add simulation context (VerilatedContext) (#2660). (#2813) 
**   Add simulation context (VerilatedContext) to allow multiple fully independent
      models to be in the same process.  Please see the updated examples.
**   Add context->time() and context->timeInc() API calls, to set simulation time.
      These now are recommended in place of the legacy sc_time_stamp().

Generate file with waivers (#2354) 
This adds the flag --generate-waivefile <filename>. This will generate
a verilator config file with the proper lint_off statemens to turn off
warnings emitted during this particular run.

This feature can be used to start with using Verilator as linter and
systematically capture all known lint warning for further
elimination. It hopefully helps people turning of -Wno-fatal or
-Wno-lint and gradually improve their code base.

Initial implementation of generic multithreaded tracing (#2269) 
The --trace-threads option can now be used to perform tracing on a
thread separate from the main thread when using VCD tracing (with
--trace-threads 1). For FST tracing --trace-threads can be 1 or 2, and
--trace-fst --trace-threads 1 is the same a what --trace-fst-threads
used to be (which is now deprecated).

Performance numbers on SweRV EH1 CoreMark, clang 6.0.0, Intel i7-3770 @
3.40GHz, IO to ramdisk, with numactl set to schedule threads on different
physical cores. Relative speedup:

--trace     ->  --trace --trace-threads 1      +22%
--trace-fst ->  --trace-fst --trace-threads 1  +38% (as --trace-fst-thread)
--trace-fst ->  --trace-fst --trace-threads 2  +93%

Speed relative to --trace with no threaded tracing:
--trace                                 1.00 x
--trace --trace-threads 1               0.82 x
--trace-fst                             1.79 x
--trace-fst --trace-threads 1           1.23 x
--trace-fst --trace-threads 2           0.87 x

This means FST tracing with 2 extra threads is now faster than single
threaded VCD tracing, and is on par with threaded VCD tracing. You do
pay for it in total compute though as --trace-fst --trace-threads 2 uses
about 240% CPU vs 150% for --trace-fst --trace-threads 1, and 155% for
--trace --trace threads 1. Still for interactive use it should be
helpful with large designs.

Improve tracing performance. (#2257) 
* Improve tracing performance.

Various tactics used to improve performance of both VCD and FST tracing:
- Both: Change tracing functions to templates to take variable widths as
  template parameters. For VCD, subsequently specialize these to the
  values used by Verilator. This avoids redundant instructions and hard
  to predict branches.
- Both: Check for value changes via direct pointer access into the
  previous signal value buffer. This eliminates a lot of simple pointer
  arithmetic instructions form the tracing code.
- Both: Verilator provides clean input, no need to mask out used bits.
- VCD: pre-compute identifier codes and use memory copy instead of
  re-computing them every time a code is emitted. This saves a lot of
  instructions and hard to predict branches. The added D-cache misses
  are cheaper than the removed branches/instructions.
- VCD: re-write the routines emitting the changes to be more efficient.
- FST: Use previous signal value buffer the same way as the VCD tracing
  code, and only call the FST API when a change is detected.

Performance as measured on SweRV EH1, with the pre-canned CoreMark
benchmark running from DCCM/ICCM, clang 6.0.0, Intel i7-3770 @ 3.40GHz,
and IO to ramdisk:

            +--------------+---------------+----------------------+
            | VCD          | FST           | FST separate thread  |
            | (--trace)    | (--trace-fst) | (--trace-fst-thread) |
------------+-----------------------------------------------------+
Before      |  30.2 s      | 121.1 s       |  69.8 s              |
============+==============+===============+======================+
After       |  24.7 s      |  45.7 s       |  32.4 s              |
------------+--------------+---------------+----------------------+
Speedup     |    22 %      |   256 %       |   215 %              |
------------+--------------+---------------+----------------------+
Rel. to VCD |     1 x      |  1.85 x       |  1.31 x              |
------------+--------------+---------------+----------------------+

In addition, FST trace size for the above reduced by 48%.

Fix to make trace code allocation dense. (#2250) 
This looks like a bits/bytes bug. The affected m_codeInc member
determines how many 32-bit words to allocate in a buffer used to store
previous values of the signal, but this was off by a factor of 8, so
we used to use too much memory.

SweRV VCD tracing speed +6.5% (excluding IO, clang 6.0), due mainly to
reduced D cache misses.

Compile fast tracing code with OPT_FAST in single compile mode. (#2245) 
When using the __ALL*.cpp based single compile mode (i.e.: without
VM_PARALLEL_BUILDS), the fast path tracing code used to be included in
__Allsup.cpp, which was compiled with OPT_SLOW, severely harming tracing
performance. We now have __ALLfast.cpp and __ALLslow.cpp instead of
__ALLcls.cpp and __ALLsup.cpp, so we can compile the fast support code
with OPT_FAST as well.

Fix FST tracing performance by removing std::map from hot path. (#2244) 
This patch eliminates a major piece of inefficiency in FST tracing
support, by using an array to lookup fstHandle values corresponding
to trace codes, instead of a tree based std::map. With this change, FST
tracing is now only about 3x slower than VCD tracing. We do require
more memory to store the symbol lookup table, but the size of that is
still small, for the speed benefit.

Asserts can be disabled by not using the `--assert` flag or by calling

Add tests for this behavior.
Bad tests check that the assert still causes a stop.
Non bad tests check that asserts are properly disabled and cause no stop

f00ff61559 Link Verilator binary partially statically, Closes #2146. 
The build is now by default configured to link performance critical
libraries (libgcc, libstdc++, libtcmalloc) statically. This improves
Verilation speed by between 4.5-7% based on my measurements as it
eliminates approx 20% of the mispredicted branches from the execution.
With partial static linking, the size of the .text section in
verilator_bin is increased by about 14%, and the binary is itself only
about 800KB bigger on disk, so hopefully this is not a big issue in
exchange for the faster compilation speed. A configure option
"--disable-partial-static" is provided to restore the old behaviour of
linking everything dynamically.

Note: This patch also changes to use libtcmalloc_minimal, which is all
we really need and itself has fewer dependencies.

ef5250f0ca Internals: Further performance improvement of AstNode type tests, #2138. No functional change intended. 
Replace the virtual type() method on AstNode with a non-virtual, inlined
accessor to a const member variable m_type.  This means that in order to be
able to use this for type testing, it needs to be initialized based on the
final type of the node. This is achieved by passing the relevant AstType
value back through the constructor call chain. Most of the boilerplate
involved is auto generated by first feeding V3AstNodes.h through astgen to
get V3AstNodes__gen.h, which is then included in V3Ast.h. No client code
needs to be aware and there is no functional change intended.

Eliminating the virtual function call to fetch the node type identifier
results in measured compilation speed improvement of 5-10% as it
eliminates up to 20% of all mispredicted branches from the execution.

As Verilator continuously allocates and releases small objects (e.g.:

time in malloc/free and friends. This patch adds the --enable-tcmalloc
configure option to link Verilator against the high performance malloc
implementation library libtcmalloc. The default is to use libtcmalloc if
available on the system. Note that there are no source code change, we
are simply replacing the standard library memory allocation functions.

Measured major compilation speed improvement of 27% when running
Verilator with -O3 on a large design.

Add lint_off -match waivers (#2102) 
* Add more directives to configuration files

Allow to set the same directives in configuration files that can also
be set by comment attributes (such as /* verilator public */ etc).

* Add support for lint messsage waivers

Add configuration file switch '-match' for lint_off. It takes a string
with wildcards allowed and warnings will be matched against it (if
rule and file also match). If it matches, the warning is waived.

Fixes #1649 and #1514 
Closes #2072

045ff25f80 Support vpiModule, bug1469. 
Add very basic support for vpiModule. Basically it allows to traverse
the module tree to find a variable etc. It does not support more than
vpi_iterate and vpi_scan for vpiModule along basic operations like
vpi_get_str on vpiModule.

The support is added non-intrusively to non-VPI verilator runs. It
essentially:

 - Tracks the creation of cell instances and keeps them alive until
   the emit phase. They are there converted to scopes if modules.

 - Emits empty (don't add anything during construction)
   VerilatedScopes for all inlined modules, only for those inlined
   modules that are on the hierarchical path to public variables.

 - Adds VerilatedHierarchy as abstraction to structure of the
   scopes. It is only created for VPI designs. It allows to traverse
   the hierarchy from the top (NULL).

d6ac351dcb Add --public-flat-rw switch, bug1511. 
This switch exposes VARs, PORTs and WIREs to C++ code. It must be use
with care as it has a significant performance impact and may result in
mis-simulation of generated clocks. Anyhow, it is prefered over
--public and useful for VPI.
