Fix memory leaks - batch 1 (#6411) 2025-09-09 22:39:44 +01:00
Geza Lore 5ffa05fba0
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.

Internals: Fix remaining cppcheck errors (#6319) 
Fixed the non const-related issue and added suppressions for the const
ones. With that `make cppcheck` should be clean.

Delete AstNode user5 (#4638) 
This saves about 5% memory. V3AstUserAllocator is appropriate for most use
cases, performance is marginally up as we are mostly D-cache bound on
large designs.

Geza Lore d60f180f43 Avoid double traversal of maps 
The typical find/if-not-exists-insert pattern can be achieved with 1
lookup instead of 2 using emplace with a sentinel value. Also maps value
initialize their values when inserted with the [] operator, this is
defined and so there is no need to explicitly insert zeroes for integer
values.
