- Z3_OP_BSMUL_NO_OVFL: a predicate to check that bit-wise signed multiplication does not overflow.
Signed multiplication overflows if the operands have the same sign and the result of multiplication
does not fit within the available bits. \sa Z3_mk_bvmul_no_overflow.
- Z3_OP_BUMUL_NO_OVFL: check that bit-wise unsigned multiplication does not overflow.
Unsigned multiplication overflows if the result does not fit within the available bits.
\sa Z3_mk_bvmul_no_overflow.
- Z3_OP_BSMUL_NO_UDFL: check that bit-wise signed multiplication does not underflow.
Signed multiplication underflows if the operands have opposite signs and the result of multiplication
does not fit within the avaialble bits. Z3_mk_bvmul_no_underflow.
- Z3_OP_BSDIV_I: Binary signed division.
It has the same semantics as Z3_OP_BSDIV, but created in a context where the second operand can be assumed to be non-zero.
- Z3_OP_BUDIV_I: Binary unsigned division.
It has the same semantics as Z3_OP_BUDIV, but created in a context where the second operand can be assumed to be non-zero.
- Z3_OP_BSREM_I: Binary signed remainder.
It has the same semantics as Z3_OP_BSREM, but created in a context where the second operand can be assumed to be non-zero.
- Z3_OP_BUREM_I: Binary unsigned remainder.
It has the same semantics as Z3_OP_BUREM, but created in a context where the second operand can be assumed to be non-zero.
- Z3_OP_BSMOD_I: Binary signed modulus.
It has the same semantics as Z3_OP_BSMOND, but created in a context where the second operand can be assumed to be non-zero.
- Z3_OP_PR_UNDEF: Undef/Null proof object.
- Z3_OP_PR_TRUE: Proof for the expression 'true'.
