* Ignore CLion project files and CMake outputs
* Supporting stripping file path that contains backslash
* Set /bigobj flag and increase stack size for windows platform
* Fix MSVC warnings
Multiple tricks to reduce the size of class FileLine from 72 to 40
bytes:
- Reduce file name index from 32 to 16 bits. This still allows 64K
unique input files, which is hopefully enough.
- Intern message/warning enable bitset and use a 16-bit index, again
allowing 64K unique sets which is hopefully enough.
- Put the m_waive flag into the sign bit of one of the line numbers.
- Use explicit reference counting to avoid overhead of shared_ptr.
Added assertions to ensure interned data fits within it's index space.
This saves ~5-10% peak memory consumption at no measurable run-time cost
on various designs.
- 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
This is a major re-design of the way code is scheduled in Verilator,
with the goal of properly supporting the Active and NBA regions of the
SystemVerilog scheduling model, as defined in IEEE 1800-2017 chapter 4.
With this change, all internally generated clocks should simulate
correctly, and there should be no more need for the `clock_enable` and
`clocker` attributes for correctness in the absence of Verilator
generated library models (`--lib-create`).
Details of the new scheduling model and algorithm are provided in
docs/internals.rst.
Implements #3278
Rename AstNodeModule::hierName -> someInstanceName and explain that this
is only used for user messages.
Rename AstNode::locationStr -> instanceStr and simplify implementation.
In particular, do not report an instance if we can't find a reasonable
guess.
