* DI: Update testcases for LLVM assembly changeDuncan P. N. Exon Smith2015-07-318-17/+18
| | | | | | | | | | Update testcases after LLVM change r243774. Most of these had no need to check `tag:` field, but did so as a way of getting to the `name:` field. In a few cases I've converted the `tag:` checks to `arg:` or `CHECK-NOT: arg:`. llvm-svn: 243775
* Add missing files for objc_boxable feature.Alex Denisov2015-07-235-0/+551
| | | | | | Original patch [r240761] is missing all new files because of committer's mistake. llvm-svn: 243018
* Fix -save-temp when using objc-arc, sanitizer and profilingSteven Wu2015-07-171-0/+27
| | | | | | | | | | | | Currently, -save-temp will cause ObjCARC optimization to be dropped, sanitizer pass to run early in the pipeline, and profiling instrumentation to run twice. Fix the issue by properly disable all passes in the optimization pipeline when generating bitcode output and parse some of the Language Options even when the input is bitcode so the passes can be setup correctly. llvm-svn: 242565
* Substitute type arguments into uses of Objective-C interface members.Douglas Gregor2015-07-071-0/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When messaging a method that was defined in an Objective-C class (or category or extension thereof) that has type parameters, substitute the type arguments for those type parameters. Similarly, substitute into property accesses, instance variables, and other references. This includes general infrastructure for substituting the type arguments associated with an ObjCObject(Pointer)Type into a type referenced within a particular context, handling all of the substitutions required to deal with (e.g.) inheritance involving parameterized classes. In cases where no type arguments are available (e.g., because we're messaging via some unspecialized type, id, etc.), we substitute in the type bounds for the type parameters instead. Example: @interface NSSet<T : id<NSCopying>> : NSObject <NSCopying> - (T)firstObject; @end void f(NSSet<NSString *> *stringSet, NSSet *anySet) { [stringSet firstObject]; // produces NSString* [anySet firstObject]; // produces id<NSCopying> (the bound) } When substituting for the type parameters given an unspecialized context (i.e., no specific type arguments were given), substituting the type bounds unconditionally produces type signatures that are too strong compared to the pre-generics signatures. Instead, use the following rule: - In covariant positions, such as method return types, replace type parameters with “id” or “Class” (the latter only when the type parameter bound is “Class” or qualified class, e.g, “Class<NSCopying>”) - In other positions (e.g., parameter types), replace type parameters with their type bounds. - When a specialized Objective-C object or object pointer type contains a type parameter in its type arguments (e.g., NSArray<T>*, but not NSArray<NSString *> *), replace the entire object/object pointer type with its unspecialized version (e.g., NSArray *). llvm-svn: 241543
* Account for calling convention specifiers in function definitions in IR test ↵David Blaikie2015-06-293-10/+10
| | | | | | | | | | | | | cases Several tests wouldn't pass when executed on an armv7a_pc_linux triple due to the non-default arm_aapcs calling convention produced on the function definitions in the IR output. Account for this with the application of a little regex. Patch by Ying Yi. llvm-svn: 240971

* Honor the objc_runtime_name attribute when encoding class/protocol names.Douglas Gregor2015-06-161-1/+15
| | | | | | | | While the rest of the Objective-C metadata seems to honor objc_runtime_name, the encoding strings produced by, e.g., @encode and property meta, were not. Fixes rdar://problem/21408305. llvm-svn: 239852

* DebugInfo: Metadata constructs now start with DI*Duncan P. N. Exon Smith2015-04-2930-104/+104
| | | | | | | | | | 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

| | | | | | | | This reverts commit r234700. It turns out that the lifetime markers were not the cause of Chromium failing but a bug which was uncovered by optimizations exposed by the markers. llvm-svn: 235553

* Remove threshold for inserting lifetime markers for named temporariesArnaud A. de Grandmaison2015-04-107-13/+190
| | | | | | | | | | | | | | | | | | | Now that TailRecursionElimination has been fixed with r222354, the threshold on size for lifetime marker insertion can be removed. This only affects named temporary though, as the patch for unnamed temporaries is still in progress. My previous commit (r222993) was not handling debuginfo correctly, but this could only be seen with some asan tests. Basically, lifetime markers are just instrumentation for the compiler's usage and should not affect debug information; however, the cleanup infrastructure was assuming it contained only destructors, i.e. actual code to be executed, and was setting the breakpoint for the end of the function to the closing '}', and not the return statement, in order to show some destructors have been called when leaving the function. This is wrong when the cleanups are only lifetime markers, and this is now fixed. llvm-svn: 234581

* DebugInfo: Attribute cleanup code to the end of the scope, not the end of ↵David Blaikie2015-02-041-7/+5
| | | | | | | | | | | | | | | | | | the function. Now if you break on a dtor and go 'up' in your debugger (or you get an asan failure in a dtor) during an exception unwind, you'll have more context. Instead of all dtors appearing to be called from the '}' of the function, they'll be attributed to the end of the scope of the variable, the same as the non-exceptional dtor call. This doesn't /quite/ remove all uses of CurEHLocation (which might be nice to remove, for a few reasons) - it's still used to choose the location for some other work in the landing pad. It'd be nice to attribute that code to the same location as the exception calls within the block and to remove CurEHLocation. llvm-svn: 228181

* Debug info for blocks: Fix a bug caught by the Verifier.Adrian Prantl2014-11-211-0/+26
| | | | | | | | | | | | When emitting nested block definitions, the insert-at-point variant of DIBuilder::insertDeclare() could be called with the insertion point set to the end-of-BasicBlock sentinel, causing the parent pointer of the CallInst to be set to the intentionally bogus value of the sentinel.

* CodeGen: correct block mangling in ObjCSaleem Abdulrasool2014-10-141-0/+29
| | | | | | | | | | | | Mangling for blocks defined within blocks in an ObjectiveC context were also broken by SVN r219393. Because the code in mangleName assumed that the code was either C or C++, we would trigger assertions when trying to mangle the inner blocks in an ObjectiveC context. Add a test and use the ObjectiveC specific mangling when dealing with an ObjectiveC method declaration. llvm-svn: 219697
