The vectorization test suite currently has a few failures that happen
because i386 is missing patterns for logical vector operations.
Altivec got these recently.

I suspect so.

bitwise operations - may need to add new patterns to i*86 (see
http://gcc.gnu.org/ml/gcc-patches/2004-04/msg00907.html).

Fixed 3 days ago by:
* config/i386/emmintrin.h (_mm_cvtsi128_si32): Move earlier.
(_mm_cvtsi128_si64x): Likewise.
(_mm_srl_epi64, _mm_srl_epi32, _mm_srl_epi16, _mm_sra_epi32,
_mm_sra_epi16, _mm_sll_epi64, _mm_sll_epi32, _mm_sll_epi16): Use
the _mm_{srl,sll}i_foo counterpart, and _mm_cvtsi128_si32.
* config/i386/i386-modes.def: Add V16HI, V32QI, V4DF, V8SF.
* config/i386/i386-protos.h: Update.
* config/i386/i386.c (print_operand): Add 'H'.
(ix86_fixup_binary_operands): Split out from ...
(ix86_expand_binary_operator): ... here.
(ix86_fixup_binary_operands_no_copy): New.
