[Qemu-arm] [PATCH v2 0/3] refactor float-to-float conversions and fix AHP

[Alex Bennée]

Hi,

This is a more polished version of the re-factoring of the softfloat
fcvt code. I've split apart the fixes for ARM alternative
half-precision format for easier review. Rather than rely on some
questionable hacks it introduces a new FloatFmt to allow cleaner
handling of the differences in the common code. If there are other
alternative floating point formats they can follow a similar approach.

I've included the test case for reference although I expect it to be
merged with my tcg-testing revival code which has the rest of the
build and test machinery for the test case.

checkpatch dumps a bunch of false-positives as it doesn't like
scientific notation for floats or inline assembler used in the test
case.

Cheers,
