[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,
