Hmm, good point, but the test feels more brittle to me in that form: ``` // GNU32: load x86_fp80, x86_fp80* // GNU64: load x86_fp80*, x86_fp80** // GNU64: load x86_fp80, x86_fp80* // MSC64: load double, double* ``` That wouldn't notice if GNU32 also used an indirect pointer for this case (as it would still match the second load - but it would notice if GNU64 stopped using an indirect pointer as the first load wouldn't be matched). I guess it'd be safer if I'd use more named regex patterns in the test to follow the chain from the argp, but then we end up with a pattern covering the bits that change due to opaque pointers too.
