[LLVMdev] wxGTK sample app compiled by llvm crashes on arm

ARM was pretty much broken in 2.7. Consider using at least 2.8

You have to configure llvm-gcc as cross-arm compiler.

> Step 2. llc minimal.bc  –march=arm –o minimal.s   (for generating arm assembly code)
This won't work. You're trying to codegen x86 IR for ARM.
