Proof step 13 from proof bits2int-sign (previous step)

bits0.first ⊦ bits0 = [], bits2uint((false ' + bitsinvert(bits1))+1) = bits2uint(bitsinvert(bits0.rest) + (false ' + bitsinvert(bits1))+1), false ∈ bits0

Heuristic var elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 14:
bits0 = boolvar + bits, boolvar ⊦ bits0 = [], bits2uint((false ' + bitsinvert(bits1))+1) = bits2uint(bitsinvert(bits) + (false ' + bitsinvert(bits1))+1), false ∈ bits0

Rule argument

seq: bits ≠ [] ⊦ (boolvar ↔ bits.first) ∧ bits0 = bits.rest ↔ bits = boolvar + bits0 subst: [bits, boolvar, bits0] → [bits0, boolvar, bits] rotate: T spec: list-data inst: bitlista name: elim-list-c

Additional information

Used simplifier rules: bits ≠ [] ⊦ (boolvar ↔ bits.first) ∧ bits0 = bits.rest ↔ bits = boolvar + bits0; (elim) Used terms: bits0, boolvar, bits
