I can't confirm this. I just checked out a tree without specifying a
release tag (assuming this gave me the mainline sources, as
gcc/version.c seems to confirm), but machmode.def is no different from
the one in 3.4.0. V4DF is thus still present.

V4DF is indeed present, but the type node is not. If you sent a testcase (I think it is possible to construct it in 10 lines, isn't it?), I would happily check for you.

- Since there is on a single acrchitecture using V16SF (sh),
it be moved there?

Yes.

Who would be doing that?

You? :-)

Just remove the V8DF line from machmode.def, move the V16SF line to config/sh/sh-modes.def, bootstrap/regtest it just in case, and post the patch and CC an SH maintainer.

Paolo
