[Mono-dev] The State Of Mono Assembly Verification?

OK, I've uploaded a first batch of ~230
verifier tests based on ECMA-335 III here:
I'd appreciate it if you could take a look and let me
know if they look OK, especially the III,3.1 and
III,3.3 tests which I'll mechanically copy and modify
to make most of the remaining tests. Feel free to
contribute tests of your own though, the README lists
tests that are missing for the ECMA sections that I've
started working on and lists rules I'm not too clear
Most of these tests assemble with both Mono and MS
ILASM except in the cases where the CIL is so borked
that it doesn't make sense (I've left these tests in
for completeness though).
Happily most of the tests are caught by the Mono
runtime which reports that invalid CIL has been found
and aborts (Mono 1.1.13). There are cases that cause
the runtime to crash and others which just run
I hope they look OK,
