Hi guys,
When I compile eglibc for ARM32 platform. I find ports/sysdeps/arm/armv6t2/memchr.S
allways be translated to thumb instructions. There is a macro named "NO_THUMB" in
this file. However I can't define this NO_THUMB through configration.
So my question is how can I compile glibc into pure arm instructions through
configration, rather than modifing makefile?
If not possible, is it necessary to add an interface for this?
Thanks,
Liu Hua
