I'm trying to find out if current HEAD NCG supports some kind of
conditional instructions. On x86/amd64 this is cmov for example and on
PPC this might be fsel. So far it looks like NCG does not know anything
about those instructions and also generic support in NCG does not look
positive from this point of view. So my conclusion would be that current
NCG does not support conditional instructions. Is my analysis correct?
Correct.
The NCG doesn't have much in the way of shared infrastructure either, so
to support conditional instructions would require modifying each of the
affected backends separately.
