Greetings, I'm curious if it's possible to link an ELF with multiple objects compiled for varying CPUs (say, SPARCv8, UltraSPARC-I, etc.) and the header of the ELF cannot be modified to state that the ELF is for the CPU of the object of the highest CPU?
MPlayer's runtime-CPU-detection depends on this, as when a VIS instruction is executed, SIGILL is caught and VIS instructions are disabled in the MPlayer binary. Right now, certain objects need to be built for UltraSPARC-I, because they contain VIS1 instructions. Obviously, the object cannot be built for SPARCv8. It seems if this weren't possible, SIGILL would be quite useless, so this is why I think there's a solution. Any thoughts? -- Derek E. Lewis delewis at acm.org http://riemann.solnetworks.net/~dlewis
