[LLVMdev] arm machine code with clang 3.2

[Tim Northover]

Hi GangRyung,

> To cross-compile for Raspberry Pi add flags -ccc-host-triple arm-eabi -marm

The modern equivalent just changes "-ccc-host-triple" to "-target"; it
looks like a plausible line for the Pi, but some details depend on the
environment you'll be executing in and what you're trying to compile.

For example you may need extra options to tell clang where the ARM/Pi
headers are located, and there are hard-float versions of at least
Linux around that would change the appropriate -mfloat-abi option.

Tim.
