Generate executable and execute: gcc -m32 -mpowerpc64 bug-qemu-ppc-again.s && ./a.out This runs silently as it should on real hardware. Under qemu (from 2013-05-02 plus the rldcl patch) I incorrectly get the error message: GMP_NUMB_CEIL_MAX_DIV3 too small This seems reproducible every time, unlike most qemu bugs that hit GMP. I haven't isolated this bug to a single instruction, but if rldcl was untested, expecting all of there here used rldicl rldimi rlwinm to be tested is perhaps over-optimistic? -- Torbjörn
