_mm_sll_epi32(s, _mm_cvtsi32_si128 (c)) instead? Or does the 'i' in 'slli' stand for 'int' not 'immediate'? I thought that the list of _mm_sl* intrinsics in the assembly reference guide (Intel doc 253667, <http://www.intel.com/design/processor/manuals/253667.pdf>, page 4-172 and 4-173) were supposed to match up one-for-one with the instructions forms (on page 4-170). The assembly reference also says that _mm_slli_epi32 generates a single instruction, as it is listed in table C-1. On the other hand, icc's documentation, <http://download.intel.com/support/performancetools/c/linux/v9/intref_cls.pdf>, on page 137, says for _mm_slli_si128, 'imm must be an immediate', but doesn't say that for _mm_slli_epi32. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32961
