Hi Harald, Looks Good to Me.

OK

Thanks

Dear all,

when simplifying the RESHAPE intrinsic we lost the string length when
the resulting array had size zero.  The attached patch sets the resulting
length from the source.

Regtested on x86_64-pc-linux-gnu.  OK for mainline?

Thanks,
Harald

Make sure that the string length is properly set during simplification
even when the resulting array is zero-sized.
