Hi all,
I'd like to ask if it is better to use "tune-xscale.conf" or "tune-iwmmx.conf"
for PXA270 based machine.

Sincerely yours,

tune-iwmmx.conf would be more appropriate

Actually, no. There are still problems left with things randomly segfaulting when
compiling everything with iwmmxt, so in OE we only activate iwmmxt for packages that
benefit from and and prove to be stable (e.g. mplayer).

For added whitespace-damaged google-juice:
#build with support for the iwmmxt instruction support (pxa270 and up)
MY_ARCH := "${PACKAGE_ARCH}"
PACKAGE_ARCH = "${@base_contains('MACHINE_FEATURES', 'iwmmxt', 'iwmmxt', '${MY_ARCH}',d)}"
MY_TARGET_CC_ARCH := "${TARGET_CC_ARCH}"
TARGET_CC_ARCH = "${@base_contains('MACHINE_FEATURES', 'iwmmxt', '-march=iwmmxt
- -mtune=iwmmxt', '${MY_TARGET_CC_ARCH}',d)}"
