qemu/target/nios2/helper.c:261:20: style:inconclusive: Found duplicate branches for 'if' and 'else' Source code is } else if (address >= 0x80000000) { /* Kernel virtual page */ return cpu_nios2_handle_virtual_page(cs, address, rw, mmu_idx); } else { /* User virtual page */ return cpu_nios2_handle_virtual_page(cs, address, rw, mmu_idx); } Which version of QEMU did you use here? Apparently it was an older version, since that code has been removed more than a year ago already: https://git.qemu.org/?p=qemu.git;a=commitdiff;h=0137c93ff8cbcebf Please make sure to use the latest release of QEMU when reporting bugs. Thanks! >Which version of QEMU did you use here? git trunk. I have no idea why Richard's patch isn't in my current version and I am disinclined to find out why. Any further work by me on qemu looks somewhat doubtful. Have fun !
