freebsd/sys/conf/Makefile.arm
Andrew Turner 46e95f646c 2 years, 10 months, 22 days after the projects/arm_eabi branch was created
make the ARM EABI the default ABI on arm, armeb, armv6 and armv6eb.

This is intended to be the default ABI from now on with the old ABI to be
retired. Because of this all users are strongly suggested to upgrade to the
ARM EABI.

As the two ABIs are incompatible it is unlikely upgrading in place will
work. Users should perform a full backup and either use an external machine
to upgrade, or install to an alternative location on their media. They
should also reinstall all ports or packages when these are available.

The only known issues are:
 - pkg incorrectly detects the ABI. This is fixed upstream, and will a
   patch will be made to the port.
 - GDB can have issues with executables built with clang.

__FreeBSD_version has been bumped.

# This makefile is constructed from a machine description:

# Most changes should be made in the machine description
# /sys/arm/conf/``machineid''
# after which you should do

# Generic makefile changes should be made in
# /sys/conf/Makefile.arm
# after which config should be rerun for all machines.

# Which version of config(8) is required.
