Dear qemu-devs,
Two questions about what seems to be a deviation in the qemu-implementation
from PowerPC specification:
1. In comparison operations (eg. PPC_OP(cmp)), why does qemu not set the SO
bit (which will be the fourth bit) of T0? The spec says that the xer_so bit
is copied into the fourt
Would this patch work with other 64-bit processors, or is it
x86-64-only? I'm mainly thinking about 64-bit PowerPCs, but I don't
know if PowerPCs uses the same method.

Can we share the implementation between targets please. We already have an
implementation of mul64 in target-i386/helper.c.
I've no real preference which implementation we use, I just don't w
Hi,
The patch below fixes the emulation of dmult and dmultu by doing a real
64x64 -> 128 multiplication.
On x86_64, it uses the mul/imul instruction, an equivalent C code (but
much slower) is provided for other architectures.
Cheers,

As far as I know wirefilter is to be placed into a VDE cable, i.e. in a

Hi,
I want to print out all memory accesses to a log file.
Fo this I instrumented the ld and st macros in
softmmu_header.h which results in the error
"error can't find a register in class
'GENERAL_REGS' while reloading 'asm'"
I tried calling an extern function from the macro
which actually fprint
