Changeset 2264 for src/ASM


Ignore:
Timestamp:

Message:

1) Major change: we now always use the efficient way of resolving labels

for the interpretation of pseudo assembly code. The inefficient way is
only used locally in ASM/Interpret.ma to prove some properties more easily.

2) AssemblyProofSplitSplit?.ma partially repaired. In particular, the main

lemma is now called correctly thanks to the previous change.
