$NetBSD: patch-src-post-planar-eq2.c,v 1.3 2012/10/23 19:57:33 apb Exp $

In affine_1d_MMX(), move the initialisation of %mm3 and %mm4 registers
into a separate asm statement, to give the compiler more freedom
for register allocation.  Fixes a problem with gcc-4.5.4 on NetBSD/i386
in which gcc complained:

eq2.c: In function 'affine_1d_MMX':
eq2.c:128:5: error: can't find a register in class 'GENERAL_REGS' while reloading 'asm'
eq2.c:128:5: error: 'asm' operand has impossible constraints
