2012-03-09[analyzer] Add support for NoRedundancy inlining mode.Anna Zaks
We do not reanalyze a function, which has already been analyzed as an inlined callee. As per PRELIMINARY testing, this gives over 50% run time reduction on some benchmarks without decreasing of the number of bugs found. Turning the mode on by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152440 91177308-0d34-0410-b5e6-96231b3b80d8

compiler errors or not. -Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time. By default, such a PCH file will be rejected with an error when trying to load it. [libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors occurred. -Have libclang API calls accept a PCH that had compiler errors. The general idea is that we want libclang to stay functional even if a PCH had a compiler error. rdar://10976363. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152192 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add new code migrator support for migrating existing Objective-C code to useTed Kremenek
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax. This introduces a new library, libEdit, which provides a new way to support migration of code that improves on the original ARC migrator. We now believe that most of its functionality can be refactored into the existing libraries, and thus this new library may shortly disappear. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152141 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-06Add clang support for new Objective-C literal syntax for NSDictionary, NSArray,Ted Kremenek
NSNumber, and boolean literals. This includes both Sema and Codegen support. Included is also support for new Objective-C container subscripting. My apologies for the large patch. It was very difficult to break apart. The patch introduces changes to the driver as well to cause clang to link in additional runtime support when needed to support the new language features. Docs are forthcoming to document the implementation and behavior of these features. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152137 91177308-0d34-0410-b5e6-96231b3b80d8

considered for inlining to 200 BBs. Setting the max to 10 BBs introduced several false negatives, we'll reevaluate the setting later on along with other inlining heuristics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152072 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-05Fix a small difference in sema and codegen views of what needs to be output.Rafael Espindola
In the included testcase, soma thinks that we already have a definition after we see the out of line decl. Codegen puts it in a deferred list, to be output if a use is seen. This would break when we saw an explicit template instantiation definition, since codegen would not be notified. This patch adds a method to the consumer interface so that soma can notify codegen that this decl is now required. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152024 91177308-0d34-0410-b5e6-96231b3b80d8

2012-03-03Frontend: Default to creating output files using temporary files + rename.Daniel Dunbar
- This is a more reliable default, as it behaves better on failure and also ensures that we create *new* files (instead of reusing existing inodes). This is useful for other applications (like lldb) which want to cache inode's to know when a file has been rewritten. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151961 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-15Remove the unuseful -fdiagnostics-show-nameDavid Blaikie
This option was added in r129614 and doesn't have any use case that I'm aware of. It's possible that external tools are using these names - and if that's the case we can certainly reassess the functionality, but for now it lets us shave out a few unneeded bits from clang. Move the "StaticDiagNameIndex" table into the only remaining consumer, diagtool. This removes the actual diagnostic name strings from clang entirely.

2012-01-27Introduce module attributes into the module map grammar, along with aDouglas Gregor
single attribute ("system") that allows us to mark a module as being a "system" module. Each of the headers that makes up a system module is considered to be a system header, so that we (for example) suppress warnings there. If a module is being inferred for a framework, and that framework directory is within a system frameworks directory, infer it as a system framework. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149143 91177308-0d34-0410-b5e6-96231b3b80d8
2012-01-26Extend the ExternalASTSource interface to allow the AST source toDouglas Gregor
provide the layout of records, rather than letting Clang compute the layout itself. LLDB provides the motivation for this feature: because various layout-altering attributes (packed, aligned, etc.) don't get reliably get placed into DWARF, the record layouts computed by LLDB from the reconstructed records differ from the actual layouts, and badness occurs. This interface lets the DWARF data drive layout, so we don't need the attributes preserved to get the answer write. The testing methodology for this change is fun. I've introduced a variant of -fdump-record-layouts called -fdump-record-layouts-simple that always has the simple C format and provides size/alignment/field offsets. There is also a -cc1 option -foverride-record-layout=<file> to take the output of -fdump-record-layouts-simple and parse it to produce a set of overridden layouts, which is introduced into the AST via a testing-only ExternalASTSource (called LayoutOverrideSource). Each test contains a number of records to lay out, which use various layout-changing attributes, and then dumps the layouts. We then run the test again, using the preprocessor to eliminate the layout-changing attributes entirely (which would give us different layouts for the records), but supplying the previously-computed record layouts. Finally, we diff the layouts produced from the two runs to be sure that they are identical. Note that this code makes the assumption that we don't *have* to provide the offsets of bases or virtual bases to get the layout right, because the alignment attributes don't affect it. I believe this assumption holds, but if it does not, we can extend LayoutOverrideSource to also provide base offset information. Fixes the Clang side of <rdar://problem/10169539>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@149055 91177308-0d34-0410-b5e6-96231b3b80d8
