[Qemu-devel] [PATCH v2] target/arm: crash on conditional instr in it block

2018-08-16 Thread Roman Kapl
If an instruction is conditional (like CBZ) and it is executed conditionally (using the ITx instruction), a jump to undefined label is generated. CBZ in IT block is an unpredictable behavior, and honouring the condition code is allowed by the spec in this case (constrained unpredictable, ARMv8, sec
