Subject: [wide-int] fixed several regressions in branch.

Message-ID: <52D5E3F9.3020503@naturalbridge.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 219 bytes --]
This patch fixes what appears to have been a long standing failure in
the conversion of tree-vect-generic.c:build_replicated_const. This
failure caused several regressions on the branch.
