2007/2/16, Simon Pickering <[EMAIL PROTECTED]>: [libc/m with VFP]
I note that the build process was a fiddle (mainly due to my not knowing the debian way), and it took a couple of goes before my CFLAGS were used for the build. I also note that when I tried using the following "-mcpu=arm1136j-s -mfpu=vfp -mfloat-abi=softfp", the build failed (I don't know why - didn't look too hard. I don't have cpu transparency setup though), but removing "-mcpu=arm1136j-s" worked, and that's what I've been using.
Yeah, that's due to licensing issues. Qemu cannot emulate ARMv6 instructions, thus the build fails if it tries to run anything compiled with the correct arch. Tuomas (who did the builds for me) noticed that there was a configure flag given for tje libc build that most likely prevented our version from actually using the vfp (the fact that it still gave a performance boost for us most likely comes from the missing thumb mode instead of using hw floats...). So we definitely need to rerun the tests we had once a better build is done... -- Kalle Vahlman, [EMAIL PROTECTED] Powered by http://movial.fi Interesting stuff at http://syslog.movial.fi _______________________________________________ maemo-developers mailing list [email protected] https://maemo.org/mailman/listinfo/maemo-developers
