Revision bb2ba61451957a452c7830a6bc0fe8b8337bcf64 authored by Raphael Cauderlier on 25 March 2019, 22:21:14 UTC, committed by Raphaël Cauderlier on 22 October 2019, 14:18:31 UTC
We essentially proved forall i,
typer.type_instruction (untyper.untype_instruction i) A = Return _ i
but this result can only be true if instructions like {FAIL; FAIL} are
forbidden in the typed world (the type inferrer cannot guess the type
of the stack between the two FAILs).
For this reason, we introduced a new boolean flag in the
syntax.instruction inductive that is true iff the instruction is a
sequence whose last element is FAIL.
