Debug Info: Use identifier to reference DIType in base type field of ptr_to_member. We introduce a new class DITypeRef that represents a reference to a DIType. It wraps around a Value*, which can be either an identifier in MDString or an actual MDNode. The class has a helper function "resolve" that finds the actual MDNode for a given DITypeRef. We specialize getFieldAs to return a field that is a reference to a DIType. To correctly access the base type field of ptr_to_member, getClassType now calls getFieldAs<DITypeRef> to return a DITypeRef. Also add a typedef for DITypeIdentifierMap and a helper generateDITypeIdentifierMap in DebugInfo.h. In DwarfDebug.cpp, we keep a DITypeIdentifierMap and call generateDITypeIdentifierMap to actually populate the map. Verifier is updated accordingly. llvm-svn: 190081

Debug Info: instead of calling addToContextOwner which constructs the context after the DIE creation, we construct the context first. Ensure that we create the context before we create a type so that we can add the newly created type to the parent. Remove last use of addToContextOwner now that it's not needed. We use createAndAddDIE to wrap around "new DIE(". Now all shareable DIEs should be added to their parents right after the creation. Reviewed off-list by Eric, Thanks. llvm-svn: 193657

Debug Info: update testing cases to specify the debug info version number. We are going to drop debug info without a version number or with a different version number, to make sure we don't crash when we see bitcode files with different debug info metadata format. llvm-svn: 195504

IR: Make metadata typeless in assembly Now that `Metadata` is typeless, reflect that in the assembly. These are the matching assembly changes for the metadata/value split in r223802. - Only use the `metadata` type when referencing metadata from a call intrinsic -- i.e., only when it's used as a `Value`. - Stop pretending that `ValueAsMetadata` is wrapped in an `MDNode` when referencing it from call intrinsics. So, assembly like this: define @foo(i32 %v) { call void @llvm.foo(metadata !{i32 %v}, metadata !0) call void @llvm.foo(metadata !{i32 7}, metadata !0) call void @llvm.foo(metadata !1, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{metadata !3}, metadata !0) ret void, !bar !2 } !0 = metadata !{metadata !2} !1 = metadata !{i32* @global} !2 = metadata !{metadata !3} !3 = metadata !{} turns into this: define @foo(i32 %v) { call void @llvm.foo(metadata i32 %v, metadata !0) call void @llvm.foo(metadata i32 7, metadata !0) call void @llvm.foo(metadata i32* @global, metadata !0) call void @llvm.foo(metadata !3, metadata !0) call void @llvm.foo(metadata !{!3}, metadata !0) ret void, !bar !2 } !0 = !{!2} !1 = !{i32* @global} !2 = !{!3} !3 = !{} I wrote an upgrade script that handled almost all of the tests in llvm and many of the tests in cfe (even handling many `CHECK` lines). I've attached it (or will attach it in a moment if you're speedy) to PR21532 to help everyone update their out-of-tree testcases. This is part of PR21532. llvm-svn: 224257
