Commit ID 7f9ebf8e86e90ea1eb68388f1be12503a3f31e56
Author Jean-Francois Romang
Date 2012-10-11 19:01:52 UTC
ARM lsb/msb assembly Implement lsb/msb using armv7 assembly instructions. msb is the easiest one, using a gcc intrinsic that generates code using the ARM's clz instruction. lsb is also using this clz instruction, but with the help of ARM's 'rbit' (bit reversing) instruction. This leads to a >2% speed gain. I also renamed 'arm-32' to the more meaningfull 'armv7' in the Makefile No functional change.
