Wilson Snyder 997d5ecdf1 Internals: Cleanup cppcheck c casts. No functional change intended. 2025-08-21 20:06:43 -04:00

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.

Internals: Improve cppcheck flow and fix up issues (#6311) 
Added cppcheck-suppressions.txt in the repo root. You can add new
patterns in there instead of having to parse the XML output.

Also configure to add the -D__GNUC__ preprocessor macro, which makes it
understand UASSERT (it understands the 'noreturn' function attribute).

Added some case by case specific suppressions and fixed up other code,
especially in V3Ast*h and V3Dfg*.h, including code generated by astgen
that had some no-ops that irks cppcheck.

One thing it does not seem to like is `const` class members with default
initializers in the class. It will assume that's always the value, even
if overridden in the constructor. We had few so removed them.

With that a lot of files in `src/` are now clean or only have a handful
of issues. Therefore, I have also deleted cppcheck_filtered, and made it
produce human readable output straight to the terminal.

Regarding cleaning up the reported nits, I kind of got bored after
V3[A-E] so pausing here. Apologies for the merge conflicts.

Tested with cppcheck 2.13.0

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.

Internals: Remove use of V3Width code from V3AstNodes (#4537). No functional change intended. 
`getCommonClassTypep` and its helper code has been moved to AstNode
class. This is a lot better place for this functionality. Moreover, it
allowed to get rid of the dependency on V3Width from generic AST-related
code.
