Title:
qemu-system-arm segfaults on "smulbb r7, r5, r5"
Status in QEMU:
Invalid
Bug description:
I'll attach a binary that runs fine with qemu-system-arm V2.2.0 but V2.7.0
segfaults.
By stepping through with gdb I found that the segfaults happens when
executing the line "smulbb r7, r5, r5" (where r7=0x1, r5=0x12).
I'll also attach a debugger screenshot.
call and output:
/opt/qemu-system-arm -M integratorcp -cpu cortex-m3 -semihosting
