We convert `APSInt`s to Z3 Bitvectors in an inefficient way for most cases. We should not serialize to std::string just to pass an int64 integer. For the vast majority of cases, we use at most 64-bit width integers (at least in the Clang Static Analyzer). We should simply call the `Z3_mk_unsigned_int64` and `Z3_mk_int64` instead of the `Z3_mk_numeral` as stated in the Z3 docs. Which says: > It (`Z3_mk_unsigned_int64`, etc.) is slightly faster than `Z3_mk_numeral` since > it is not necessary to parse a string. If the `APSInt` is wider than 64 bits, we will use the `Z3_mk_numeral` with a `SmallString` instead of a heap-allocated `std::string`. Differential Revision: https://reviews.llvm.org/D78453 |
