[PATCH] [AArch64] Override useAA and remove unneeded edges in the scheduling graph

[Sanjin Sijaric]

Hi,

 

This patch removes edges in the scheduling graph between stores/loads off
the same base register if memory accesses do not overlap.   We saw an
improvement on eembc/automark on a cortex-a53 device, as well as a small
improvement on spec2000/eon.  No significant performance changes were
observed on cortex-a57, but this may be more relevant on in-order
architectures.  

 

Would this be of interest to anyone?  If so, can someone please review?

 

Thanks,

Sanjin
