Hello!

Attached patch merges "Parallel bitwise logical operations" section of
sse.md.  In addition to the merge, the patch also enables these
patterns for TARGET_SSE (using PS version of the insn) and handles
TARGET_SSE_PACKED_SINGLE_INSN_OPTIMAL target flag.

2011-04-12  Uros Bizjak  <ubizjak@gmail.com>

	* config/i386/sse.md (VI): New mode iterator.
	(SSEMODEI): Remove.
	(AVX256MODEI): Ditto.
	(AVXMODEF4P): Ditto.
	(avxvecpsmode): Ditto.
	(one_cmpl<mode>2): Enable for TARGET_SSE.  Use VI mode iterator.
	(sse2_andnot<mode>3): New expander.
	(*andnot<mode>3): Merge with *sse2_andnot<mode>3 and
	*avx_andnot<mode>3.  Enable for TARGET_SSE.  Use VI mode iterator.
	Handle TARGET_SSE_PACKED_SINGLE_INSN_OPTIMAL target flag.
	(<any_logic:code><mode>3): Use VI mode iterator.
	(*<any_logic:code><mode>3): Merge with *sse2_<any_logic:code><mode>3
	and *avx_<any_logic:code><mode>3.  Enable for TARGET_SSE.  Use VI mode
	iterator.  Handle TARGET_SSE_PACKED_SINGLE_INSN_OPTIMAL target flag.
	(*andnottf3): Handle AVX three-operand constraints.  Enable for
	TARGET_SSE.  Handle TARGET_SSE_PACKED_SINGLE_INSN_OPTIMAL target flag.
	(<any_logic:code>tf3): Enable for TARGET_SSE.
	(*<any_logic:code>tf3): Handle AVX three-operand constraints.
	Enable for TARGET_SSE.  Handle TARGET_SSE_PACKED_SINGLE_INSN_OPTIMAL
	target flag.

Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu
{,-m32} AVX target.

Patch was committed to mainline SVN.

Uros.
