[Qemu-devel] [PULL 101/130] target-ppc: Altivec 2.07: vmuluw Instruction

[Alexander Graf]

From: Tom Musta <address@hidden>

This patch adds the Vector Multiply Unsigned Word Modulo (vmuluwm)
instruction.

The existing VARITH_DO macro is re-used to (trivially) instantiate
the helper code.

Since bits 21-31 of any vmuluwm instruction is 137, the instruction
is coded as a dual to vmulouw (bits 21-31 = 136).
