Silviu Baranga	6f46bb1705	Fixed the DAG combiner to better handle the folding of AND nodes for vector types. The previous code was making the assumption that the length of the bitmask returned by isConstantSplat was equal to the size of the vector type. Now we first make sure that the splat value has at least the length of the vector lane type, then we only use as many fields as we have available in the splat value. ... llvm-svn: 163203	2012-09-05 08:57:21 +00:00
Tim Northover	876c151146	Use VLD1 in NEON extenting-load patterns instead of VLDR. ... On some cores it's a bad idea for performance to mix VFP and NEON instructions and since these patterns are NEON anyway, the NEON load should be used. llvm-svn: 155630	2012-04-26 08:46:29 +00:00
James Molloy	44927f5296	Fix bad EXTRACT_SUBREG in instruction selection for extending-loads on NEON. ... llvm-svn: 154915	2012-04-17 08:18:00 +00:00
James Molloy	3604b95957	An oversight when applying the patches for r150956 and r150957 to a vanilla tree meant I forgot to svn add these testcases. ... Noticed while investigating PR12274! llvm-svn: 154090	2012-04-05 10:01:12 +00:00
