Hi,
probably this is a problem of the original software ?

gcc -march=k6-3 -O2 -pipe -m3dnow -mmmx -fomit-frame-pointer -I. -c -fPIC -DPIC ./jccolor.c
{standard input}: Assembler messages:
{standard input}:53: Error: value of ffffffffffffff7f too large for field of 1 bytes at 00000000000000e0
make: *** [jccolor.lo] Error 1

!!! ERROR: media-libs/jpeg-6b-r3 failed.
!!! Function src_compile, Line -235, Exitcode 2
!!! (no error message)

thanks for suggestions

Does the problem persist when mmx and 3dnow are turned off?

too bad... nope, didn't work. BTW the same is valid for media-libs/jpeg-mmx

What version of GCC are you using? Does changing the arch to i586 help?

I have the same problem. Only, my flags are:

-march=k6-2 -O3 -pipe -fomit-frame-pointer

I just installed gentoo a few days ago, so my gcc version should be the
latest from the bootstrap script

piece of cake.

i586 did it. Sick enough, i could stick with my other flags:
CFLAGS="-march=i586 -O2 -pipe -m3dnow -mmmx -fomit-frame-pointer"

Since i notice the jpeg-mmx, i am curious now. I assume this would give me a bit of advantage and i guess it's the same thing in proniple. How ould i switch from jpeg to jpeg-mmx cleanly ? Unmerge jpeg, emerge jpeg-mmx ?
tanks.
