+ 
+       * config/i386/i386.c (classify_argument): Treat V1xx modes the same as 
+       their base modes. CTImode, TCmode, and XCmode must be passed in 
memory. 
+       TFmode (__float128) must be is an SSE/SSEUP pair. V2SImode, V4HImode, 
+       and V8QI are class SSE. All sufficiently small remaining vector modes 
+       must be passed in one or two integer registers. 
+       (ix86_libcall_value): TFmode must be returned in xmm0, XCmode must be 
+       returned in memory. 
+       (bdesc_2arg, ix86_init_mmx_sse_builtins): __builtin_ia32_pmuludq and 
+       __builtin_ia32_pmuludq128 have non-uniform argument and return types 
+       and must thus be handled explicitly. 
+       * config/i386/i386.md (*movdi_1_rex64): Add cases for moving between 
+       MMX and XMM regs. 
+       (movv8qi_internal, movv4hi_internal, movv2si_internal, 
+       movv2sf_internal): Permit moving between MMX and XMM registers (since 
+       MMX areguments and return values are passed in XMM registers). 
+       (sse2_umulsidi3): Correct type and mode.
