[Qemu-devel] [PATCH 00/15] tcg field extract primitives

[Richard Henderson]

I was fooling around with a new target last weekend, and got myself
all turned around with its field extract instruction.  How much more
handy would it be, I told myself, if we had such a thing generically?

In addition, many hosts have this natively.  So it seems a shame to
not take advantage of it when we can.

Lightly tested on x86_64, ppc64le, arm32, and s390x hosts.
