Building with LLVM/Clang for ARM
================================
When using LLVM/Clang to compile for ARM, it is necessary to specify
extra flags in order to enable ARM EHABI compliant exceptions. To do
so, set `OBJCFLAGS` to this:
-O2 -g -mllvm -arm-enable-ehabi -mllvm -arm-enable-ehabi-descriptors
If you are getting errors from the assembler about instructions being
unavailable for the architecture, you need to set `OBJC` to this:
clang -arch armv6 -mfpu=vfp
Using these flags, ObjFW was compiled successfully for Android and the
Raspberry Pi.

Building with LLVM/Clang for ARM
================================
When using LLVM/Clang older than 3.5 to compile for ARM, it is necessary to
specify extra flags in order to enable ARM EHABI compliant exceptions. To do
so, set `OBJCFLAGS` to this:
-O2 -g -mllvm -arm-enable-ehabi -mllvm -arm-enable-ehabi-descriptors
If you have a CPU supporting VFP or NEON, it is important to set the correct
architecture, as otherwise VFP / NEON registers won't be saved and restored
when forwarding. For example, if you have an ARMv6 that supports VFP, you
need to set `OBJC` to this:
clang -march=armv6 -mfpu=vfp
Using these flags, ObjFW was compiled successfully for Android and the
Raspberry Pi.
