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. It seems that these instructions are not supported in QEMU.
Is this a bug?
