The previous has_coalesced_range counter has a problem in that it only
works for additions of coalesced mmio ranges but not deletions. The
reason is that has_coalesced_range information can be lost when the
FlatView updates the topology again when the updated region is not
covering the coalesced

Peter Xu (2):
memory: Inherit has_coalesced_range from the same old FlatRange
It is a workaround of current KVM's KVM_UNREGISTER_COALESCED_MMIO
interface. The kernel interface only allows to unregister an mmio
device with exactly the zone size when registered, or any smaller zone
that is included in the device mmio zone. It does not support the

Just FYI that was the second bisect I had to do, the first time it
produced an even more unrelated commit, so I assumed I must have done
something wrong... apparently that is still the case. After trying the

Type: series
Subject: [Qemu-devel] [PATCH v2 00/68] target/arm: Convert aa32 base isa to
decodetree
From: "Paul A. Clarke"
helper_todouble() was not properly converting any denormalized 32 bit
float to 64 bit double.
Fix-suggested-by: Richard Henderson

v2:
- Splitting patch "ppc: Three floating point fixes"; this is just one part.
- Original suggested "fix"
There are only two remaining uses of gen_bx_im. In each case, we
know the destination mode -- not changing in the case of gen_jmp
or changing in the case of trans_BLX_i. Use this to simplify the
surrounding code.
For trans_BLX_i, use gen_jmp for the actual branch. For gen_jmp,
use
Now that everything is converted, remove the rest of
the legacy decode.

By shifting the 16-bit input left by 16, we can align the desired
portion of the 48-bit product and use tcg_gen_muls2_i32.

Since all of the inputs and outputs are i32, dispense with
the intermediate promotion to i64 and use tcg_gen_mulu2_i32
and tcg_gen_add2_i32.

Convert the modified immediate form of the data processing insns.
For A32, we can finally remove any code that was intertwined with
the register and register-shifted-register forms.

Convert the register shifted by register form of the data
processing insns. For A32, we cannot yet remove any code
because the legacy decoder intertwines the immediate form.

This unifies the implementation of the actual instructions for
a32, t32, and t16.
This has been tested by running the debian 9 armhf installer,
which does a far amount of switching between arm and thumb modes.
I've also run Peter's ARM TFM image, and all of the existing
RISU tests that we have.
This function already includes the test for an interworking write
to PC from a load. Change the T32 LDM implementation to match the
A32 LDM implementation.
For LDM, the reordering of the tests does not change valid
behaviour because the only case that differs is has rn == 15,
which is

Hi,
Recently I'm working to enable Qemu icount mode with TCG, with source code
review I found that Qemu can give deterministic execution for guest code
timeout. But for exact time point for guest OS, I have a question:
