Wilson Snyder 4ad1dde723 Internals: Emit newlines for AstCStmt automatically. No functional change intended. 2025-09-26 08:25:47 -04:00

Internals: Refactor generate construct Ast handling (#6280) (#6470) 
Internals: Refactor generate construct Ast handling (#6280)

We introduce AstNodeGen, the common base class of AstGenBlock,
AstGenCase, AstGenFor, and AstGenIf, which together represent all SV
generate constructs. Subsequently remove AstNodeFor, AstNodeCase
(AstCase is now directly derived from AstNodeStmt) and adjust internals
to work on the new representation.

Output is identical modulo hashes do to changed AstNode type ids, no
functional change intended.

Step towards #6280.

Fix AddressSanitizer issues (#6406) 
These are all genuine bugs, brief descriptions.

1. V3OrderCFuncEmitter.h used to delete a node early that was still
   reference in a graph dump later. Not a big deal, it can be deleted
   later at the end of V3Order.

2. V3Param.cpp: this one is tricky. The variable referenced by
   AstVarXRef was deleted at the end of `visit(AstGenCase*)`, but then
   `visit(AstVarXRef*)` checks `nodep->varp()` (already deleted) to see
   if it's in an interface.

3. V3String::wildMatch is sometimes called with an empty 's' (the string
   we are matching against tha pattern 'p'), in which case it used to go
   off into the woods. Added check on call. An arbitrary number of `*`
   will still match the empty string.

4. V3Task.cpp: There was an error reported for an unsupported construct,
   then a subsequent SEGV. Just signal the error upward so we bail on an
   error in a more graceful way.

5. verylog.y: Some unsupported constructs failed to set the parsed node,
   so some memory thrash made it into some code downstream. Just parse
   these into nullptr.

Also increased the timeout on one test, which sometimes tripped with
asan on GCC during heavy host load.
