fix stack corruption! Previously, 16-byte whole-FP-register stores were
...
being treated as needing only 8 bytes (though they were 16 byte aligned.)
This should fix a bunch of tests - anyone have any comments, though?
- in Target.td , SpillSize and SpillAlignment seem dead - is this what
Size and Alignment do now?
- in CodeGenRegisters.h/CodeGenTarget.cpp , DeclaredSpillSize and
DeclaredSpillAlignment seem dead.
- there are a bunch of comments here and there that don't clearly
distinguish between 'size' and 'spillsize' etc. hmm.
