* DebugInfo: Metadata constructs now start with DI*Duncan P. N. Exon Smith2015-04-291-18/+18
| | | | | | | | | | LLVM r236120 renamed debug info IR constructs to use a `DI` prefix, now that the `DIDescriptor` hierarchy has been gone for about a week. This commit was generated using the rename-md-di-nodes.sh upgrade script attached to PR23080, followed by running clang-format-diff.py on the `lib/` portion of the patch. llvm-svn: 236121
* DebugInfo: Move new hierarchy into place (clang)Duncan P. N. Exon Smith2015-03-031-19/+47
| | | | | | | Update testcases for LLVM change in r231082 to use the new debug info hierarchy. llvm-svn: 231083

* IR: Add 'distinct' MDNodes to bitcode and assembly (clang)Duncan P. N. Exon Smith2015-01-081-1/+1
| | | | | | | | | Update testcases for LLVM change in r225474 to make `MDNode`s explicitly distinct (when they aren't uniqued). Part of PR22111. llvm-svn: 225475
* IR: Make metadata typeless in assembly, clang sideDuncan P. N. Exon Smith2014-12-151-14/+14

* Revert "Revert "DI: LLVM schema change: fold constants into string""Duncan P. N. Exon Smith2014-10-031-10/+10
| | | | | | | | | | | | | | This reverts commit r218917, effectively reapplying r218913. Original commit message follows. -- Update debug info testcases for an LLVM metadata schema change to fold metadata constant operands into a single `MDString`. Part of PR17891. llvm-svn: 219011

* Debug info: Use the vbtable offset for virtual bases in the MS ABIReid Kleckner2014-08-071-2/+15
| | | | | | | | There are no vtable offset offsets in the MS ABI, but vbtable offsets are analogous. There are no consumers of this information yet, but at least we don't crash now. llvm-svn: 215149
* Revert "Debug info: Use record layout to find vbase offsets instead of vtables"Reid Kleckner2014-08-071-8/+2
| | | | | | | | | This reverts commit r215137. This doesn't work at all, an offset-offset is probably different than an offset. I'm scared that this passed our normal test suite. llvm-svn: 215141
* Debug info: Use record layout to find vbase offsets instead of vtablesReid Kleckner2014-08-071-2/+8
| | | | | | | | | This fixes an assertion when generating full debug info in the MS ABI for classes with virtual bases. Fixes PR20579. llvm-svn: 215137
* Revert "DebugInfo: Place global constants in their appropriate context."David Blaikie2014-04-051-8/+1
| | | | | | | | | This reverts commit r205655. Breaks the compiler-rt build with an assertion failure in LLVM... reverting while I investigate. llvm-svn: 205664
* DebugInfo: Place global constants in their appropriate context.David Blaikie2014-04-041-1/+8
| | | | | | | We also don't need to duplicate the name in the LinkageName field. Just leave it empty. llvm-svn: 205655
* DebugInfo: PR19298: function local const variables duplicated in the root scopeDavid Blaikie2014-04-041-6/+10
| | | | | | | | | | | | | | See the comment for CodeGenFunction::tryEmitAsConstant that describes how in some contexts (lambdas) we must not emit references to the variable, but instead use the constant directly - because of this we end up emitting a constant for the variable, as well as emitting the variable itself. Should we just skip putting the variable on the stack at all and omit the debug info for the constant? It's not clear to me - what if the address of the local is taken? llvm-svn: 205651

* Debug Info: generate a unique identifier for C++ struct, class, union, and enum.Manman Ren2013-08-291-8/+9
| | | | | | | | | | | | | | | | We use CXX mangler to generate unique identifier for external C++ struct, union, class and enum. Types with unique identifier are added to retained types by DIBuilder. Testing cases are updated to reflect the unique identifier generated for types. The order of MDNodes is changed because of retained types and testing cases are updated accordingly. Testing case debug-info-uuid.cpp now emits error with Itanium mangler, since uuid is not yet handled in Itanium mangler. And it will check for the error message. llvm-svn: 189622
* Debug Info: this reverts commit r189600.Manman Ren2013-08-291-9/+8
| | | | | | | | We had further discussions on how to retain types, whether to do it in front end or in DIBuilder. And we agree to do it in DIBuilder so front ends generating unique identifier do not need to worry about retaining them. llvm-svn: 189609
* Debug Info: generate a unique identifier for C++ struct, class, union, and enum.Manman Ren2013-08-291-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | We use CXX mangler to generate unique identifier for external C++ struct, union, class and enum. Types with unique identifier are added to RetainedTypes to make sure they are treated as used even when all uses are replaced with the identifiers. A single type can be added to RetainedTypes multiple times. For example, both createForwardDecl and createLimitedType can add the same type to RetainedTypes. A set is used to avoid duplication when updating AllRetainTypes in DIBuilder. Testing cases are updated to reflect the unique identifier generated for types. The order of MDNodes is changed because of retained types and testing cases are updated accordingly. Testing case debug-info-uuid.cpp now emits error with Itanium mangler, since uuid is not yet handled in Itanium mangler. We choose to update RetainedTypes in clang, then at finalize(), we update AllRetainTypes in DIBuilder. The other choice is to update AllRetainTypes in DIBuilder when creating a DICompositeType with unique identifier. This option requires using ValueHandle for AllRetainTypes in DIBuilder since the created DICompositeType can be modified later on by setContainingType etc. llvm-svn: 189600
* Debug Info: follow-up patch to r189283.Manman Ren2013-08-261-1/+1

* DebugInfo: handle the DI asm printing change to reword '[fwd]' as '[decl]' ↵David Blaikie2013-06-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | and add '[def]' for non-decl tag types This is to make test cases looking for definitions more legible by making the definition explicit rather than just the absence of '[fwd]'. This allowed the debug-info-record tests to be rephrased - and in the interests of reducing the number of individual test cases/invocations we have, I merged them into one file, separated them with namespaces (& then moved them to C++ because namespaces are great). If they need to remain 'C' only tests, they can be moved back. (I didn't group them with 'debug-info-class.cpp' because these tests only apply to -fno-limit-debug-info) I removed the pieces of code that would cause these tests to pass under -flimit-debug-info to ensure the tests remain relevant to their fixes should we ever improve -flimit-debug-info to catch that kind of code. This commit is version locked with the corresponding change to DebugInfo.h in LLVM. Except some transient buildbot fallout. llvm-svn: 184524

| | | | | | | | | | On Windows, it looks like FlagIndirectVariable is being set in Flags for DIBuilder::createLocalVariable(), giving us an i32 of 8192 instead of 0, as on Linux. Fixes breakage from r184367. llvm-svn: 184438

* PR14763: Debug info for non-trivial record parametersDavid Blaikie2013-06-051-0/+17
| | | | | | | | | | There seems to have been some erroneous code attempting to describe the ABI of parameters (non-trivial record parameters are passed by reference). This would break the type of the function (especially when it caused a mismatch between the type of a declaration & a definition) causing PR14763 and PR14645. llvm-svn: 183329
* PR16214: Debug Info: -flimit-debug-info doesn't omit definitions for types ↵David Blaikie2013-06-051-0/+24
| | | | | | | | | | | | | | | | | | | | used via typedefs In an effort to make -flimit-debug-info more consistent I over-shot the mark & made types used via typedefs never produce definitions in the debug info (even if the type was used in a way that would require a definition). The fix for this is to do exactly what I was hoping to do at some point - plumb the declaration/definition choice through the various layers of "CreateType" in CGDebugInfo. In this way we can produce declarations whenever they are sufficient & definitions otherwise - including when qualifiers are used, for example (discovered in PR14467). This may not be complete (there may be other types/situations where we need to propagate the "declaration/definition" choice) but it lays the basic foundation which we can enhance in future iterations. llvm-svn: 183296

* DebugInfo: Simply & constrain test(s) for PR9600/PR9608David Blaikie2013-05-091-1/+10
| | | | | | | | | | | | | | | | | | | | | Both these tests were ultimately fixed by the check for "isIncompleteType" & neither test case was really reduced to a minimal form. On doing so it becomes apparent that the problem wasn't specific to templates at all, so I've moved the test case to a more appropriate test file and added FileCheck verification to it (to show the forward declaration of the array element type as well as the array alignment and size being 0 since it cannot be computed). That's about as far down this rabbithole as I'm willing to go today, so the rest of the un-FileChecked tests in test/CodeGenCXX/debug-info.cpp will have to go another day without actually testing anything other than the fact that they don't crash. & improve the actually interesting test case in test/CodeGenCXX/debug-info-templates.cpp which was my original goal (in preparation for expanding it/fixing some related bugs in non-type template parameters) llvm-svn: 181552

| | | | | | | | | - This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). llvm-svn: 91446
