...onsidered as common for all targets. And the second reason, why I’d prefer to generate a splat-GEP, is compile-time saving. I should generate 2 (or more, for each splat element) redundant instructions (broadcast is insert+shuffle), hoist them outside the loop on some stage. Then look for them on CodeGenPreare pass, sink them back and rebuild the CFG. - Elena From: Nadav Rotem [mailto:nrotem at apple.com] Sent: Monday, March 02, 2015 19:01 To: Demikhovsky, Elena Cc: llvmdev at cs.uiuc.edu; Duncan P.

Hi, According to the current GEP syntax, vector GEP requires that each index must be a vector with the same number of elements. %A = getelementptr <4 x i8*> %ptrs, <4 x i64> %offsets I propose to lessen this requirement. Let each index be or vector or scalar. All vector indices must have the same number of elements. The scalar value will mean the splat vector value. %A =
