How To Build On ARM

Introduction
============
This document contains information about building/testing LLVM and
Clang on ARM.
Notes On Building LLVM/Clang on ARM
=====================================
Here are some notes on building/testing LLVM/Clang on ARM. Note that
ARM encompasses a wide variety of CPUs; this advice is primarily based
on the ARMv6 and ARMv7 architectures and may be inapplicable to older chips.
#. If you are building LLVM/Clang on an ARM board with 1G of memory or less,
please use ``gold`` rather then GNU ``ld``.
Building LLVM/Clang with ``--enable-optimized``
is prefered since it consumes less memory. Otherwise, the building
process will very likely fail due to insufficient memory. In any
case it is probably a good idea to set up a swap partition.
#. If you want to run ``make
check-all`` after building LLVM/Clang, to avoid false alarms (eg, ARCMT
failure) please use the following configuration:
.. code-block:: bash
$ ../$LLVM_SRC_DIR/configure --with-abi=aapcs
