I'm fascinated by the Pure algebraic/functional language. The Pure interpreter uses the LLVM JIT compiler as its backend.

I would like to compile Pure so that it runs on Android(ARM). Pure has a dependency on the LLVM JIT. So I need to compile LLVM source for Pure to run.

Is it possible to compile LLVM source for Android (ARM) devices? There really seems to be no information about this on the web. Maybe my search terms are wrong. Searching for Android LLVM does not bring up many good hits either.

It now seems possible, the NDK now supports Clang which uses LLVM. So maybe it can be made to work with any LLVM language. AOSP should give us some insight on how they added Clang support. See the latest Android NDK for details on Clang support.

Android NDK, Revision 8c (November 2012)
Important changes:
Added the Clang 3.1 compiler to the NDK. The GNU Compiler Collection (GCC) 4.6 is still the default, so you must explicitly enable the Clang compiler option as follows:
For ndk-build, export NDK_TOOLCHAIN_VERSION=clang3.1 or add this environment variable setting to Application.mk.
For standalone builds, add --llvm-version=3.1 to make-standalone-toolchain.sh and replace CC and CXX in your makefile with /bin/clang and /bin/clang++. See STANDALONE-TOOLCHAIN.html for details.
Note: This feature is experimental. Please try it and report any issues.
