Hi Alli have written a java program, keep sending the gdb single step

We have -- or will have -- several targets which have a native
multiply-highpart instruction: ppc*, ia64, aarch64, alpha.
If we leave only the mul[us]2 opcode with which to expose this,
we have to handle the register allocation bits in the backends.
Better, IMO, to expose the two parts at the TCG
With the optimization in tcg_liveness_analysis,
we can avoid the MFLO when it is unused.

With this we no longer pass down envp, and thus all systems can have

No need to set up a SIGILL signal handler for detection anymore.
Remove a ton of sanity checks that must be true, given that we're
requiring a 64-bit build (the note about 31-bit KVM is satisfied

The getauxval routine was added to glibc for 2.16. In order to
better support qemu on systems prior to 2.16, add a qemu_getauxval

Hi,
The fundamental reason is traditional qemu-dm and upstream qemu using a
different vgabios-cirrus.bin,
qemu-dm is using xen-4.1.2/tools/firmware/vgabios/
VGABIOS-lgpl-latest.cirrus.bin,
but upstream qemu is using qemu-1.2.2/pc-bios/vgabios-cirrus.bin
the pivotal patch is :

The QEMU mascot which was already used for the NSIS installer
is now used for all QEMU executables.
