Patch had been included here: http://git.qemu.org/?p=qemu.git;a=commitdiff;h=e44a90c59697cf98 ==> Fix released ** Changed in: qemu Status: New => Fix Released -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1308381 Title: illegal instructions for AArch64 ARMv8 Status in QEMU: Fix Released Bug description: The test case is in the attachment. To reproduce as following (I tried both GCC and Clang): $aarch64-linux-gnu-gcc qemu.c -o test $./test qemu: uncaught target signal 4 (Illegal instruction) - core dumped Illegal instruction (core dumped) In the test case, 3 intrinsics are tested: vqmovunh_s16, vqmovuns_s32, vqmovund_s64. They will be compiled into instructions: SQXTUN Bd, Hn SQXTUN Hd, Sn SQXTUN Sd, Dn. QEMU is get from trunk git://git.qemu.org/qemu.git. Other instructions work well.
