[Ffmpeg-devel] [PATCH] "p" asm constraint in swscale_template.c

[Reimar Döffinger]

Hello,
I stumbled over this because icc can not compile it. Can someone tell me
what using "p" instead of "r" is good for? Any reason not to just change
it to "r"? I did test on 32 bit with icc 9.1 and on 64 bit with gcc 4.1
so far.

Greetings,
Reimar D?ffinger
