From ef96e3ae9698d6726a8113f448c82985a9f31ff5 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Wed, 2 Jan 2019 09:14:22 +0000 Subject: target/ppc: move FP and VMX registers into aligned vsr register array The VSX register array is a block of 64 128-bit registers where the first 32 registers consist of the existing 64-bit FP registers extended to 128-bit using new VSR registers, and the last 32 registers are the VMX 128-bit registers as show below: 64-bit 64-bit +--------------------+--------------------+ | FP0 | | VSR0 +--------------------+--------------------+ | FP1 | | VSR1 +--------------------+--------------------+ | ... | ... | ... +--------------------+--------------------+ | FP30 | | VSR30 +--------------------+--------------------+ | FP31 | | VSR31 +--------------------+--------------------+ | VMX0 | VSR32 +-----------------------------------------+ | VMX1 | VSR33 +-----------------------------------------+ | ... | ... +-----------------------------------------+ | VMX30 | VSR62 +-----------------------------------------+ | VMX31 | VSR63 +-----------------------------------------+ In order to allow for future conversion of VSX instructions to use TCG vector operations, recreate the same layout using an aligned version of the existing vsr register array. Since the old fpr and avr register arrays are removed, the existing callers must also be updated to use the correct offset in the vsr register array. This also includes switching the relevant VMState fields over to using subarrays to make sure that migration is preserved.
