Hi,
i have seen questions on the mailing list about march for arm926ejs being mentioned as -march=armv4.
---snip---
But according to the Wikipedia (http://en.wikipedia.org/wiki/ARM_architecture ) , architecture version for ARM926EJ-S is ARMv5TEJ.
Correct Please confirm, off list, that you can access http://infocenter.arm.com/ for your future ARM architecture investigations....
Kindly can someone explain why this is done. Previously few have provided the patch but all have been rejected or not applied.
I think the position is that -march=armv4 is compatible with more toolchains and builds code which runs on all later architectures, whilst the correct architecture setting provides minimal benefits (to U-Boot).
However, I'm still working on my compiler options patch, mainly to satisfy the list comments re -msoft-float.
I hope to have it available for the next merge window.
Meanwhile you can get the current snapshot from www.linux-arm.org/git/u-boot-armdev.git/080212_options.
I'd be interested in your comments.
Regards
Peter
