[LLVMdev] The right option combination to compile into ARM/Thumb2 code.
Hi Karel,
It actually looks like the argument parser has parsed "thumb -mattr=v7,thumb2,vfp3" as the full argument to "-march=". Strange.
The easiest way to get what you want is probably "-mtriple thumbv7--". v7 has Thumb2 enabled and VFPv3 (along with NEON) by default.
Cheers,
James

[LLVMdev] The right option combination to compile into ARM/Thumb2 code.
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
