I'm not aware of any problems with aarch64 semihosting. If QEMU crashes that's definitely a bug -- can you provide us with a reproduce case (eg the binary you used here)? > Some time ago I reworked the semihosting implementation in OpenOCD, and > there I used a common semihosting implementation for all Arm and RISC-V > devices; everything worked fine, so a common approach is realistic. Yes; QEMU also shares code for those two architectures' semihosting implementation. thanks -- PMM
