I'm seeing the same pattern.
Infact, I'm noticing a lot of my maths code seems to be performing a lot of
redundant moves.

Are there actually any builtins/intrinsics available for the SH4?
How do I access the awesome vector operations without breaking out the inline
asm?

It would be nice to have some intrinsics that understand vectors as sequences
of 4 float regs, and automate a sequential (vector) load.

Also, the ftrv opcode doesn't seem to be accessible either.
