ARM version confusion

Note: This was originally posted on 12th December 2011 at http://forums.arm.com

The arch ref manual provides syntax for numerous (all?) assembler instructions.
I'm writing code for arm1176jzf-s with the vfpv2 fpu.

Which of the options can/can't I use in the instruction set provided there please?

My choices are commonly

ARMv4T, ARMv5T*, ARMv6*, ARMv7, ARMv6T2, ...

I know I can't use the ARMv7 set, are there others to avoid too?

TIA DaveP

The 1176 implements ARMv6Z, which is basically ARMv6 + Security Extension (aka TrustZone).

So I'd suggest ARMv6*

Thanks for that.

Yet to find out about Security Extensions!
