--- Comment #2 from Dave Cheney <dave at cheney.net> ---
Thank you for your comment.

I disagree that this bug is a duplicate of 20757. Having read the referenced
issue I believe you were suggesting that if I move the .arch directive to the
header of the file, ie, the top, this will fix the problem

$ clang -c gcc_arm.s 
gcc_arm.s:3:2: error: instruction requires: armv5t
        blx r5 // setg(g) 
$ cat gcc_arm.s 
.arch armv5t
    blx r5 // setg(g) 

Sadly this does not appear to be the case.
