[PATCH] [ARM] Be Conservative when coalescing into SP

[Quentin Colombet]

Hi Matthias,

I tend to agree with you that the coalescer is correct since the encoding permit it. On the other hand, this is the only pass I am aware of that messed up with the reserved register. E.g., the machine copy propagation pass would not create such pattern.

Cheers,
-Quentin
