From 194576157afb34f7ce69cde800bf9715c730b39f Mon Sep 17 00:00:00 2001 From: Filip Navara Date: Thu, 15 Oct 2009 12:45:57 +0200 Subject: target-arm: convert NEON VZIP/VUZP/VTRN helper functions to pure TCG The neon_trn_u8, neon_trn_u16, neon_unzip_u8, neon_zip_u8 and neon_zip_u16 helpers used fixed registers to return values. This patch replaces that with TCG code, so T0/T1 is no longer directly used by the helper functions. Bugs in the gen_neon_unzip register load code were also fixed.
