[PATCH] D133118: Fix invalid llvm.dbg.declare after instcombine (#56807)

[Matthias Gehre via Phabricator via llvm-commits]

mgehre-amd added inline comments.


================
Comment at: llvm/test/Transforms/InstCombine/dbg-cast-of-allocation.ll:13
+; CHECK-NEXT:    %pixels = alloca i16
+; CHECK-NEXT:    call void @llvm.dbg.declare(metadata i16* %pixels, metadata ![[MD:[0-9]+]], metadata !DIExpression()), !dbg ![[DBG:[0-9]+]]
+; CHECK-NEXT:    call void @foo(i16* nonnull %pixels)
----------------
Before this PR, the first argument used to be "undef"


================
Comment at: llvm/test/Transforms/InstCombine/dbg-simplify-alloca-size.ll:11
+; CHECK-NEXT:    %pixels1 = alloca [3 x i8], align 1
+; CHECK-NEXT:    call void @llvm.dbg.declare(metadata [3 x i8]* %pixels1, metadata ![[MD:[0-9]+]], metadata !DIExpression()), !dbg ![[DBG:[0-9]+]]
+; CHECK-NEXT:    %pixels1.sub = getelementptr inbounds [3 x i8], [3 x i8]* %pixels1, i64 0, i64 0
----------------
Before this PR, the first argument used to be `%pixels1.sub`.
