Hi,
After https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01615.html we error
on the use of constraints in define_splits, define_expands and
define_peephole2s. These are never looked at by the compiler, and so
have no reason to be set.
I expect there will be more fallout as Jan's auto-builder makes its way
through ports I haven't tested, I'll fix those up as they come up.
These are build failures, and the fixes are "obvious", but I don't know
my way around these ports, so I'd like an explicit maintainer ack.
For testing, I've just checked that the build error is resolved. In
principal, these are not functional changes as the constraints are
not looked at.
OK?
Thanks,
James
