* Replace llvm::DIBuilder::DisableDebugLocations() with two RAII interfacesAdrian Prantl2013-07-181-1/+38
| | | | | | | | | | | | | inspired by CodegenFunction::LexicalScope. - NoLocation temporarily turns off debug locations altogether. This is useful for emitting instructions that should be counted towards the function prologue. - BuiltinLocation temporarily switches to an artificial debug location that has a valid scope, but no line information. This is useful when emitting compiler-generated helper functions that have no source location associated with them. llvm-svn: 186552

| | | | | | | | | | | | | | | emit the full definition of a type in -flimit-debug-info This simplifies the core benefit of -flimit-debug-info by taking a more systematic approach to avoid emitting debug info definitions for types that only require declarations. The previous ad-hoc approach (3 cases removed in this patch) had many holes. The general approach (adding a bit to TagDecl and callback through ASTConsumer) has been discussed with Richard Smith - though always open to revision. llvm-svn: 186262

* Rewrite record layout for ms_struct structs.Eli Friedman2013-06-261-11/+0
| | | | | | | | | | | | | | The old implementation of ms_struct in RecordLayoutBuilder was a complete mess: it depended on complicated conditionals which didn't really reflect the underlying logic, and placed a burden on users of the resulting RecordLayout. This commit rips out almost all of the old code, and replaces it with simple checks in RecordLayoutBuilder::LayoutBitField. This commit also fixes <rdar://problem/14252115>, a bug where class inheritance would cause us to lay out bitfields incorrectly. llvm-svn: 185018
* [AST] Introduce a new DecayedType sugar nodeReid Kleckner2013-06-241-0/+4
| | | | | | | | | | | | | | The goal of this sugar node is to be able to look at an arbitrary FunctionType and tell if any of the parameters were decayed from an array or function type. Ultimately this is necessary to implement Microsoft's C++ name mangling scheme, which mangles decayed arrays differently from normal pointers.

* DebugInfo: ensure negative enumerators are emitted as suchDavid Blaikie2013-06-241-1/+1
| | | | | | | | | | There's still a problem here - since we're not appropriately using the signedness/range of the enum to chooset the encoding and emission of enumerators, but GCC has some bugs around this too so I assume that's not /such/ a high priority though I may get to it soon out of completeness. llvm-svn: 184695

* PR14763: Debug info for non-trivial record parametersDavid Blaikie2013-06-051-16/+0
| | | | | | | | | | 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 Blaikie2013-06-051-33/+21
| | | | | | | | | | | | | | | | | | | | 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: Rename CreatePointerType to getOrCreateTypeDeclarationDavid Blaikie2013-05-241-9/+11
| | | | | | | | | | | | | | | | To make this more consistent with 'getOrCreateType' & clarify the distinction between the two. The only thing I couldn't quite communicate in the name is that getOrCreateTypeDeclaration may actually produce a full definition (in -fno-limit-debug-info) but the point is to call it whenever only a declaration is needed & the implementation can choose whether to provide a declaration or definition. (also, unfortunately, getOrCreateType can produce declarations too - we should sure this up by making it not do that - any caller that can tolerate a declaration should be calling getOrCreateTypeDeclaration instead) llvm-svn: 182674
* PR16091: Error when attempting to emit debug info for undeduced auto return ↵David Blaikie2013-05-241-2/+7
| | | | | | | | | | | | types Perhaps we should just suppress this, rather than erroring, but since we have the infrastructure for it I figured I'd use it - if this is determined to be not the right thing we should probably remove that infrastructure entirely. I guess it's lying around from the early days of implementing debug info support. llvm-svn: 182673

* Revert "Revert "Debug Info: Using declarations/DW_TAG_imported_declaration ↵David Blaikie2013-05-201-9/+56
| | | | | | | | | | | | | | | | | | | | | of variables, types, and functions."" This reverts commit r181947 (git d2990ce56a16050cac0d7937ec9919ff54c6df62 ) This addresses one of the two issues identified in r181947, ensuring that types imported via using declarations only result in a declaration being emitted for the type, not a definition. The second issue (emitting using declarations that are unused) is hopefully an acceptable increase as the real fix for this would be a bit difficult (probably at best we could record which using directives were involved in lookups - but may not have been the result of the lookup). This also ensures that DW_TAG_imported_declarations (& directives) are not emitted in line-tables-only mode as well as ensuring that typedefs only require/emit declarations (rather than definitions) for referenced types. llvm-svn: 182231
