Dear GCC Steering Committee,
We have a request from a customer to implement support for a single
element vectors in gcc for one of their processors. Their ABI
requires that vectors are handled differently from ordinary types,
and it includes a single element, 64-bit vector which GCC would
normally consider to be exactly equivalent to a long long.
I have suggested to them that they reconsider this support for
single element vectors, but they wish to keep it. I also suggested
that although it is possible to add this feature, it was likely to
be rejected by you. Was I correct in making this assertion ?
If so, they would like to know why single element vectors should not
be supported. What ramifications does it have and what would
supporting them break ?
Cheers
Nick Clifton
