Title: linux-user qemu-arm NEON support Status in QEMU: Invalid Bug description: I was reading the mailing list and saw NEON support in QEmu was making progress. Is it not supported in user mode? or am I running into something else here? (I've tried to include some what may be useful information) using qemu from git (last commits as below): fdaad47 Merge remote-tracking branch 'remotes/pmaydell/tags/pull-target-arm-20140501' into staging e50bf23 Merge remote-tracking branch 'remotes/kevin/tags/for-upstream' into staging c090c10 Merge remote-tracking branch 'remotes/cohuck/tags/kvm_cap_helpers' into staging (for completeness I should point out this is not actually libQtCore.so.4.6.2 - the SONAME shows libQt5Core.so.5). chorler@linux-foxtrot:~/projects/src/CustomFirmware> qemu-arm -L ./root ./root/usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/libQtCore.so.4.6.2 qemu: unhandled CPU exception 0x2 - aborting R00=00000000 R01=f6c84fdd R02=00000000 R03=00000000 R04=00000000 R05=00000000 R06=00000000 R07=00000000 R08=00000000 R09=00000000 R10=f6ff9d80 R11=00000000 R12=00000000 R13=f6c84d90 R14=00000000 R15=f6cdef74 PSR=00000010 ---- A usr32 qemu: uncaught target signal 6 (Aborted) - core dumped Aborted chorler@linux-foxtrot:~/projects/src/CustomFirmware> arm-linux-gnueabihf-readelf -A ./root/usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/libQtCore.so.4.6.2 Attribute Section: aeabi File Attributes Tag_CPU_name: "7-A" Tag_CPU_arch: v7 Tag_CPU_arch_profile: Application Tag_ARM_ISA_use: Yes Tag_THUMB_ISA_use: Thumb-2 Tag_FP_arch: VFPv3 Tag_Advanced_SIMD_arch: NEONv1 Tag_ABI_PCS_wchar_t: 4 Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_align_needed: 8-byte Tag_ABI_align_preserved: 8-byte, except leaf SP Tag_ABI_enum_size: int Tag_ABI_HardFP_use: SP and DP Tag_ABI_VFP_args: VFP registers Tag_ABI_optimization_goals: Aggressive Speed Tag_CPU_unaligned_access: v6 Tag_DIV_use: Not allowed chorler@linux-foxtrot:~/projects/src/CustomFirmware> gdb qemu-arm GNU gdb (GDB; openSUSE 13.1) 7.6.50.20130731-cvs Copyright (C) 2013 Free Software Foundation, Inc.
