[Mesa3d-dev] RE: Texutil optimizations - an interesting story

[<ad...@hu...>]

Ok, this didn't get thru, so here it is (sorry for the confusion)

Hi Gareth,

would you mind taking a look at the attached file for a couple more ways 
of doing the texture depth conversions?

I separated the main for loops and stuck them in a file for easier testing 
of the code. I hope that's not a problem?

I am not sure which is the faster one as I don't have a decent profiling 
setup in Linux [any help on this would be appreciated as the last time i 
did serious code instruction profiling was back in high school with Abrash's 
 self-adjusting code ex: i really like all the benchmarks that you give 
us on this list and the DRI list as far as improvments (or not) of various 
codes...]

Also, i am not sure if the code is endian safe. I only thought of the Intel/little 
endian case.

Also, can you remind me how to direct gcc to not use the stack but rather 
use the registers some more? 

thanks,
tony
