[glibc-ports.git] / ChangeLog.arm

2011-03-21  Ulrich Weigand  <ulrich.weigand@linaro.org>

        * sysdeps/unix/sysv/linux/arm/eabi/nptl/sysdep-cancel.h (PSEUDO): Add
        missing "cmn r0, $4096" for _nocancel system call stubs.

2011-03-21  Ulrich Weigand  <ulrich.weigand@linaro.org>

        * sysdeps/unix/sysv/arm/eabi/sysdep.h (DO_CALL): Do not save/restore
        r7 into IP.
