Subject: ia64: convert widen_[us]sum into convert optab [PR122069]
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f60eb809708f3594dbe2debc6fd228a5796e15f;p=thirdparty%2Fgcc.git

ia64: convert widen_[us]sum into convert optab [PR122069]

The target does not seem to have a maintainer listed, I've CC'ed a group of
global maintainers instead hoping one of you could approve it.

This patch is a mechanical rewrite of the widen_[us]sum optabs from a direct to
a conversion optab.  The result of which requires the output mode to be added to
the existing patterns.

No change in functionality is expected.
