Hi All, This RFC patch series implements a simple align divisor shift dividend method for 64bit divide and enables for ARMv7-a.
This algorithm runs (K+1) times where K is the number of bits divisor is shifted to align. I have done repeated divides and found that this implementation performs better for processor without hw divide instruction. On a chromebook, when K is large (close to 64) this performs on an average ~10% faster. When K is small (8 to 24), it performs about ~100% faster on an average. Regression tested on arm-none-linux-gnueabi with no issues. OK? Thanks, Kugan
