Internals: Add VL_MT_SAFE annotations to const functions (#3681) 2022-10-18 17:07:09 -04:00
Krzysztof Bieganski 68927d4fd3
Make class ref typing stricter (#3671) 
Prevents the possibility of assigning an integer to a class reference,
both at the SystemVerilog and the emitted C++ levels.

Geza Lore 63c694f65f Streamline dump control options 
- 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

Geza Lore 8681861be9 Improve bitop tree optimization 
- Remove redundant casting
- Cheaper final XOR parity flip (~/^1 instead of != 0)
- Support XOR reduction of ~XOR nodes
- Don't add redundant masking of terms
- Support unmasked terms
- Add cheaper implementation for single bit only terms
- Ensure result is clean under all circumstances (this fixes current bugs)

Geza Lore 24b3816f5e Improve distribution of V3Hash/V3Hasher 
- Better combining, without multiplication, which means a 0 hash value
is now allowed.
- Do not OR in bottom bits (this was used to avoid a 0 hash but had the
side effect of hashing 0 and 1 to the same value, which are actually
common inputs.
- Hash whole content of V3Number. This does not seem to be noticeable in
runtime, but quite often the bottom word can be a special value like
zero while the rest of the content varies.

Rework Ast hashing to be stable (#2974) 
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.
