I wonder what is the clean way to handle this situation in libunwind since most of their functions are expanded (with c macro) at compile time to the platform dependent version, for example unw_get_reg becomes: $ objdump -x strace | grep get_reg | grep UND 0000000000000000 F *UND* 0000000000000000 _Ux86_64_get_reg So in theory we could even statically declare a link against both -lunwind-x86_64 and -lunwind-x86 (or the corresponding ARM libs) and then do a bunch of dlsym with the arch dependent function names in case we are stracing different personalities. That will get quite messy though.
