-- qemu-system-m68k does not accept "notw %d" instruction https://bugs.launchpad.net/bugs/547227 You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. Status in QEMU: Invalid Bug description: The notw and notb instructions does not work with latest version of qemu-system-m68k. I've tried both 0.12.3 and the latest git version compiled about an hour ago, both running on Arch Linux. The executable fails with the following output: > qemu-system-m68k -nographic -M an5206 -kernel test.elf qemu: fatal: Illegal instruction: 4640 @ 00000006 D0 = 00000000 A0 = 00000000 F0 = 0000000000000000 ( 0) D1 = 00000000 A1 = 00000000 F1 = 0000000000000000 ( 0) D2 = 00000000 A2 = 00000000 F2 = 0000000000000000 ( 0) D3 = 00000000 A3 = 00000000 F3 = 0000000000000000 ( 0) D4 = 00000000 A4 = 00000000 F4 = 0000000000000000 ( 0) D5 = 00000000 A5 = 00000000 F5 = 0000000000000000 ( 0) D6 = 00000000 A6 = 00000000 F6 = 0000000000000000 ( 0) D7 = 00000000 A7 = 00000000 F7 = 0000000000000000 ( 0) PC = 00000000 SR = 2700 ----- FPRESULT = 0 zsh: abort qemu-system-m68k -nographic -M an5206 -kernel test.elf I've attached the test.elf file, which produces the bug. It contains the following: > m68k-elf-objdump -m 68000 -D test.elf test.elf: file format elf32-m68k Disassembly of section .text: 00000000 <start>: 0: 4e71 nop 2: 4e71 nop 4: 4e71 nop 6: 4640 notw %d0 00000008 <loop>: 8: 6000 fffe braw 8 <loop> It works when removing the not instruction. There might be other non-working instructions, I've only tested a few. Hope you'll get the bug fixed. Thanks.
