Markus Lavin 8b493e1580 Reland [DebugInfo] Improve dbg preservation in LSR. ... Use SCEV to salvage additional @llvm.dbg.value that have turned into referencing undef after transformation (and traditional salvageDebugInfo). Before rewrite (but after introduction of new induction variables) use SCEV to compute an equivalent set of values for each @llvm.dbg.value in the loop body (among the loop header PHI-nodes). After rewrite (and dead PHI elimination) update those @llvm.dbg.value now referencing undef by picking a remaining value from its equivalence set. Allow match with offset by inserting compensation code in the DIExpression. Fixes : PR38815 Differential Revision: https://reviews.llvm.org/D87494		2020-12-14 16:15:18 +01:00
