Nick,

would you mind having a brief look at  this bug report? It seems to be a pretty old one which may 
no longer even be present, but it also includes a patch... Thanks,

Dara

Unfortunately the v850 port does not even build at the moment, so I
cannot test the patch.  Once I have fixed the build problems I will
have a look at it though, OK ?

Cheers

Thanks, sounds good... I'll leave it in WAITING in case the submitter can confirm it's fixed on 
previous versions.

Thank you. I have just been able to try with 3.1.1., 
and as far as I understand it seems to be O.K.

Thanks for the feedback. I think we should leave this open until v850 bootstraps, and Nick can 
make certain the problem is fixed. Thanks,

Dara

P.S. Nick, if you disagree, feel free to close this report.

Now that v850-elf builds again, it looks like 3.4 produces identical asm to 
3.1.1 for this testcase. Nick, does this mean this problem is fixed?

Closing as this is fixed on the mainline.
