First off: does this seem correct?
Yes. Though I do wonder why you are avoiding using the normal libcall machinery. If all you really care about is changing the function name, then all you need to do is modify the appropriate optab. See, for instance, arm_init_libfuncs.
But if you need slightly different calling conventions, then this will work just fine. Compare this to the Alpha TFmode routines generated by alpha_emit_xfloating_libcall.
However, I am unsure this is possible in the expand stage, would the expand stage automatically have this instead: mult tmp1, a, b mult tmp2, c, d mov output1, tmp1 mov output2, tmp2 call bar
Yes, this is exactly what expand_call does. r~
