error message:

But some small pieces of the HPPA backend still survived until

(like the disassembler code, or the detection of HPPA in the

All operations that take a floatx80 as an operand need to have their
inputs checked for malformed encodings. In all of these cases, use the
function floatx80_invalid_encoding to perform the check. If an invalid
operand is found, raise an invalid operation exception, and then return
either NaN (for fp-typed results) or the integer indefinite value (the
minimum representable signed integer value, for int-typed results).
For the non-quiet comparison operations, this touches adjacent code in
order to pass style checks.

In user-mode emulation env->idt.base memory is
allocated in linux-user/main.c with
size 8*512 = 4096 (for 64-bit).
When fake interrupt EXCP_SYSCALL is thrown
do_interrupt_user checks destination privilege level
for this fake exception, and tries to read 4 bytes
at address base + (256 * 2^4)=4096, that causes
segfault.
Privlege level was checked only for int's, so lets

If giving QEMU a log arg which asks to enable multiple
different trace event patterns such as
$QEMU -d trace:qio*,trace:qcrypto*
the parser will then invoke
trace_enable_events("qio*,trace:qcrypto*")
trace_enable_events("qcrypto*")
as when finding a 'trace:' prefix, it is not clever
enough to strip anything after the next comma. As
a result only the last 'trace:' match ever works.
Rather than trying to be more clever with parsing the
command line arg in place, simplify the code by
using g_strsplit to break it into individual strings
on ','. These resulting pieces can be directly used
without worrying about trailing data from the next
option.

From the trace we can see there is an interrupt window exit
after the first interrupt EOI(irq 62), and the same irq(62)
is injected duplicately after the interrupt window.
QEMU does KVM_INTERRUPT(62) ioctl after KVM exits with
KVM_EXIT_IRQ_WINDOW_OPEN, which QEMU requested while the
guest was printing. The printing calls
serial_update_irq() -> qemu_irq_lower() -> qemu_set_irq() ->
gsi_handler() -> qemu_set_irq() -> pic_irq_request() ->
apic_deliver_pic_intr() -> kvm_handle_interrupt()
kvm_handle_interrupt() does
interrupt_request |= CPU_INTERRUPT_HARD
which later calls cpu_get_pic_interrupt() in kvm_arch_pre_run(),
but that function uses stale information from APIC and injects
62 again. If we synchronized the APIC, then the test would #GP,
because there would be no injectable interrupt in LAPIC or PIC,
so pic_read_irq() would return 15, thinking it was spurious.
This patch fix it by don't touch LAPIC if LAPIC is in kernel.

Windows uses object properties to determine the size of a file, so to

doesn't use this property, it seems, so we can cheat a bit and just use
