[llvm-dev] LLVM ignoring cross_compilation flag

[Raul Garcia via llvm-dev]

Hello,

I am trying to cross compile LLVM version 3.3 for ARM ( i know it is a little bit old but I want to use llvm-perf tool). I used the xilinx toolchain. Here build is the intel platform and the host the arm processor. When I configure before compilation I observe that the cross compilation is detected, however when I execute the make command, the cross compilation flag is overridden/ignored. I am missing something here to be able to generate LLVM binaries for ARM, are the commands that I use correct?
