Sanjay Patel 25a4b4195f [InstCombine] fold bitcasts around an extractelement (3rd try) ... This is a redo of r255137 (reverted at r255227) which was a redo of r255124 (reverted at r255126) with a fixed check for a scalar source type and an added test for the failure that caused the revert. Original commit message: Example: bitcast (extractelement (bitcast <2 x float> %X to <2 x i32>), 1) to float ---> extractelement <2 x float> %X, i32 1 This is part of fixing PR25543: https://llvm.org/bugs/show_bug.cgi?id=25543 The next step will be to generalize this fold: trunc ( lshr ( bitcast X) ) -> extractelement (X) Ie, I'm hoping to replace the existing transform of: bitcast ( trunc ( lshr ( bitcast X))) added by: http://reviews.llvm.org/rL112232 with 2 less specific transforms to catch the case in the bug report.
