* 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.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
