Hello,
I'm trying to convince llc to compile into thumb2 ISA on ARMv7. I'm using:
-march=thumb -mattr=v7,thumb2,vfp3
but llc complains about this with:
llc: error: invalid target 'thumb -mattr=v7,thumb2,vfp3'
I'm using LLVM from Aug 29 2011. To me the set of options looks sane so I'd like to ask what's wrong with this.
Thanks! Karel
