* Introduce X-macro-based trace tag definition
- Created trace_tags.def to centralize TRACE tag definitions
- Each tag includes a symbolic name and description
- Set up enum class TraceTag for type-safe usage in TRACE macros
* Add script to generate Markdown documentation from trace_tags.def
- Python script parses trace_tags.def and outputs trace_tags.md
* Refactor TRACE_NEW to prepend TraceTag and pass enum to is_trace_enabled
* trace: improve trace tag handling system with hierarchical tagging
- Introduce hierarchical tag-class structure: enabling a tag class activates all child tags
- Unify TRACE, STRACE, SCTRACE, and CTRACE under enum TraceTag
- Implement initial version of trace_tag.def using X(tag, tag_class, description)
(class names and descriptions to be refined in a future update)
* trace: replace all string-based TRACE tags with enum TraceTag
- Migrated all TRACE, STRACE, SCTRACE, and CTRACE macros to use enum TraceTag values instead of raw string literals
* trace : add cstring header
* trace : Add Markdown documentation generation from trace_tags.def via mk_api_doc.py
* trace : rename macro parameter 'class' to 'tag_class' and remove Unicode comment in trace_tags.h.
* trace : Add TODO comment for future implementation of tag_class activation
* trace : Disable code related to tag_class until implementation is ready (#7663).
- range and fixed restrictions on terms are based on constraints and can be violated temporarily.
- bv_eval currently does not allow updating over fixed bits which leads to non-termination. TODO
- lookahead only considers tabu when setting values of variables.
- avoid more platform specific behavior when using m_mk_extract,
- rename mk_eq in bool_rewriter to mk_eq_plain to distinguish it from mk_eq_rw
- rework bv_lookahead to be more closely based on sls_engine, which has much better heuristic behavior than attempt 1.
* Logical names for function declarations in c++
Currently, for example, the function declaration symbol member for
checking whether multiplication *does not* overflow is called
`m_bv_smul_ovfl`. Since we are introducing the upcoming smtlib2 symbols
that check that multpliciation *does* overflow, the not overflow check
symbols are renamed to `m_bv_smul_no_ovfl` etc.
* Implement smtlib overflow preds for multiplication
Smtlib2 is being extended to include overflow predicates for bit
vectors (see https://groups.google.com/u/1/g/smt-lib/c/J4D99wT0aKI).
This commit introduces the predicates `bvumulo` and `bvsmulo` that
return `true` if the unsigned multiplication overflows or the signed
multiplication underflows or overflows, respectively.
* Move mul overflow predicates to BV logic
* Add a todo on illogical argument order
* Implement mk_unary_pred for bv
* Implement bvnego
* Implement bvuaddo
* Implement bvsaddo
* Implement bvusubo
* Implement bvssubo
* Implement bvsdivo
* Fixed problem with registering bitvector functions
* Added rewriting distinct with bitvectors to false if bit-size is too low
* Removed debug output
* Incorporated Nikolaj's comments
* Simplifications
