Wilson Snyder d60a3e2b66 Fix random internal crashes (#666). 
Internally, in V3Broken check m_interpp for null, and make several cleanups
in the addNext/addNextHere/unlinkFr* methods.

Internals: Add VL_MT_SAFE annotations to const functions (#3681) 2022-10-18 17:07:09 -04:00
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 ce03293128 Generate AstNode accessors via astgen 
Introduce the @astgen directives parsed by astgen, currently used for
the generation child node (operand) accessors. Please see the updated
internal documentation for details.

Also add checks to t/t_dist_cppstyle

Geza Lore 0c70a0dcbf Remove redundant 'virtual' keywords from overridden methods 
'virtual' is redundant when 'override' is present, so keep only
'override'.

Add t/t_dist_cppstyle.pl to check for this.

Geza Lore 539c9d4c63 Merge alternate 'force'/'release' implementation 
- Add more tests, including for tracing.
- Apply some cleaner, more generic abstractions in the implementation.
- Use clearer AstRelease which is not an assignment.

Geza Lore 5ad3c4e499 Internals: Speed up and improve V3Broken 
This patch makes OpenTitan verilation with --debug-check 22% faster, and
the same with --debug --no-dump-tree 91% faster. Functionality is the
same (including when VL_LEAK_CHECKS is defined), except V3Broken can now
always find duplicate references via child/next pointers if the target
node is not `maybePointedTo()` (previously this only happened when
compiled with VL_LEAK_CHECKS). The main change relates to storing the
v3Broken traversal state in the AstNode by stealing a byte from what
used to be unused flags. We retain an unordered_set only for marking
pointers as valid to be referenced via a non-child/non-next member
pointer.
 2021-07-11 21:03:17 +01:00
Geza Lore 766ad14ae0 Check function locals are referenced only when in scope 
V3Broken now checks that AstVar nodes referenced in an AstCFunc are
either external, or appear in the tree before the reference, and are in
scope.

Fix V3Begin to move lifted AstVars to beginning of FTask, rather than
end, which trips the above check.
