Hi,

I am optimizing libjepeg code crosscompiling it with arm and by changing the compiler flags. Can anyone help me to direct to a link which shows all the options to optimize. Currently I am using
O3 - Optimization level
mcpu = cortex
-pipe.
 

can add "-mfpu=neon" as well for Neon support is it is supported in processors like cortex-A8/A9/A5 etc
