| 15 | Notes On Building LLVM/Clang on ARM
|
| 16 | =====================================
|
| 17 | Here are some notes on building/testing LLVM/Clang on ARM. Note that
|
| 18 | ARM encompasses a wide variety of CPUs; this advice is primarily based
|
| 19 | on the ARMv6 and ARMv7 architectures and may be inapplicable to older chips.
|

|
| 21 | #. If you are building LLVM/Clang on an ARM board with 1G of memory or less,
|
| 22 | please use ``gold`` rather then GNU ``ld``.
|
| 23 | Building LLVM/Clang with ``--enable-optimized``
|
| 24 | is prefered since it consumes less memory. Otherwise, the building
|
| 25 | process will very likely fail due to insufficient memory. In any
|
| 26 | case it is probably a good idea to set up a swap partition.
|
| 27 |
|
| 28 | #. If you want to run ``make
|
| 29 | check-all`` after building LLVM/Clang, to avoid false alarms (eg, ARCMT
|
| 30 | failure) please use the following configuration:
|
| 31 |
|
| 32 | .. code-block:: bash
|
| 33 |
|
| 34 | $ ../$LLVM_SRC_DIR/configure --with-abi=aapcs
