Richard,
It's been 6 months so I thought I'd check in again. Do you have an estimate
of when this will go in?

OK, thanks for the update. I also appreciate you looking at the NaN issue.

Just curious. What's the expected timeline to get these denormal patches in
the tree?

with a NaN operand, float_flag_inorm_denormal should not be set (and that way,
the DE bit in MXCSR won't be set when it shouldn't be).

I have another couple of thoughts around input denormal handling.
The first is straightforward. I noticed that the Aarch64 port doesn't report
input denormals (I could not find any code which sets the IDC bit in the FPSR).
I found code in the arm (not aarch64) port that sets other bits like
single flag
combined with the "flush_inputs_to_zero" flag to accomplish what the two
separate "input denormal" flags do?

, are you willing to make the change or do you want me to try?
Thanks,

I see support in QEMU for architectures which have a denormal input flag bit
and those that have a "flush inputs to zero" control bit, but the
implementation is not specializable and seems wrong for x86 at least.
For example, in sf_canonicalize, if the input is denormal and
