* 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).
* z3str3: check consistency of str.to_int in fixed length solver
* z3str3: add similar check for int.to_str as well
* z3str3: refactor string-integer conversion check and add post checks for model construction
* regex needs lesson; m.mk_eq not ctx.mk_eq
* when unsat core is of size 0, then do naive learning
* remove two extra comments, and correct positive regex learning
* replace magic numbers for fixed-length lessons with constants
* z3str3: make counterexamples less naive, and check regex membership more efficiently
* z3str3: construct even better counterexamples for regex membership
* z3str3: remove legacy fixed-length overlap testing
parameter smt.str.fixed_length_overlap_models has been deprecated
* z3str3: remove legacy length/value testing algorithm and binary search heuristic
the following parameters are deprecated:
smt.str.use_binary_search
smt.str.binary_search_start
smt.str.fixed_length_models (the fixed-length model construction is now always used)
* z3str3: remove legacy regex unroll methods
* z3str3: remove unused methods and member variables
