weldon washburn commented on HARMONY-1430:
------------------------------------------

>From looking at the patch, it looks to be localized mods to only Jitrino.OPT.  I am OK with applying this patch.  Also, does there need to be a regression test for this problem?  Or will a regression test appear when abcd is rewritten?

> The bug in optimizing simple arithmetic instruction consist of two parts:
>     - copy/paste caused bug in simplifier::simplifyAnd(xxx)
>     - erroneuos conversion elimination in abcd
> The first is fixed in the code.
> The second is fixed by turning off conversion elimination in abcd.
> (It should be rewritten completely later)
> The second bug: Jitrino does not throw a LinkingException when ldc tries to load
> incorrect class literal.
> As 1.5 support is available 'ldc' can loads class literals.
> These classes may be incorrect (not resolved successfully).
> It actually does not distrub ldc activity but according to specification
> LinkingException must be thrown.
> Bugfix:ThrowLinkingException helper call is generated at the place of ldc in managed
> code if literal type can not be resolved.
> The issue depends on HARMONY-1363
