Proof step 21 from proof validstatfield-addclass-other (previous step)

mkfs(class0, ty, fieldvar) ' ∈ statfields(class0), tdname∃(str, class0) ⊦ class0 = class, class = `java.lang.Object' .class, initdone(class0, st) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', addclass(class, fis, st)) ↔ initdone(class0, st) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st)

User applied rule cut formula

And obtained the following new goals

Proof step 20:
initdone(class0, st), mkfs(class0, ty, fieldvar) ' ∈ statfields(class0), tdname∃(str, class0) ⊦ class0 = class, class = `java.lang.Object' .class, initdone(class0, st) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', addclass(class, fis, st)) ↔ initdone(class0, st) → validfield(str, jvmref, mkfs(class0, ty, fieldvar) ', st)

Rule argument

[fma-arg: initdone(class0, st)]
