2009-04-10PCH serialization/deserialization of the source manager. With thisDouglas Gregor
improvement, source locations read from the PCH file will properly resolve to the source files that were used to build the PCH file itself. Once we have the preprocessor state stored in the PCH file, source locations that refer to macro instantiations that occur in the PCH file should have the appropriate instantiation information. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68758 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09Implementation of pre-compiled headers (PCH) based on lazyDouglas Gregor
de-serialization of abstract syntax trees. PCH support serializes the contents of the abstract syntax tree (AST) to a bitstream. When the PCH file is read, declarations are serialized as-needed. For example, a declaration of a variable "x" will be deserialized only when its VarDecl can be found by a client, e.g., based on name lookup for "x" or traversing the entire contents of the owner of "x". This commit provides the framework for serialization and (lazy) deserialization, along with support for variable and typedef declarations (along with several kinds of types). More declarations/types, along with important auxiliary structures (source manager, preprocessor, etc.), will follow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68732 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-09Make -include, -imacros paths absolute in Frontend.Daniel Dunbar
- Otherwise paths will be resolved relative to the main input file, which is incorrect. - I don't know how to make a reasonable test case for this with our testing infrastructure. - PR3395 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68665 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68640 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08According to the GCC man page, all -imacros are included before any -include's.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68633 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08properly escape filenames when generating implicit #includes, this handlesChris Lattner
things like " in paths etc. Found by inspection. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68632 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Add initial support for -imacros. Right now it has the same semantics asChris Lattner
-include, but that will be fixed soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68625 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08More fixes to builtin preprocessor defines.Daniel Dunbar
- Add -static-define option driver can use when __STATIC__ should be defined (instead of __DYNAMIC__). - Don't set __OPTIMIZE_SIZE__ on Os, __OPTIMIZE_SIZE__ is tied to Oz. - Set __NO_INLINE__ following GCC 4.2. - Set __GNU_GNU_INLINE__ or __GNU_STDC_INLINE__ following GCC 4.2. - Set __EXCEPTIONS for Objective-C NonFragile ABI. - Set __STRICT_ANSI__ for standard conforming modes. - I added a clang style test case in utils for this, but its not particularly portable and I don't think it belongs in the test suite. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68621 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-08Make debug info work when using -save-temps.Daniel Dunbar
- This is pretty ugly, but the most obvious solution. Chime in if you have a nicer one. - The problem is that with -save-temps, clang-cc has no idea what the name of the original input file is. However, the user expects to be able to set breakpoints based on the input file name. - We support this by providing a new option -main-file-name (similar to -dumpbase used by gcc) which allows the driver to pass in the original file name. - <rdar://problem/6753383> building with clang using --save-temps gets the compile unit name from the .i file... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68595 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-08Set __PIC__ (more) correctly.Daniel Dunbar
- Add -pic-level clang-cc option to specify the value for the define, updated driver to pass this. - Added __pic__ - Added OBJC_ZEROCOST_EXCEPTIONS define while I was here (to match gcc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68584 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Fix forwarding of -{std,ansi,trigraphs} when there areDaniel Dunbar
multiple instances of an option. Also, removed direct -ansi support from clang-cc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68558 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-07Driver: Manually translate a number of -f with no- variants options toDaniel Dunbar
clang. - We will eventually want some more driver infrastructre for this probably. - For now, the clang-cc interface stays relatively the same, but we don't accept multiple instances anymore, or the [no-] variants directly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68550 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-07implement rdar://6762183. I'm not sure if it is more insane thatChris Lattner

2009-04-02Fixup -ftrapv to be more gcc compatible. -ftrapu (for want of aMike Stump
better name) is the option that SmallTalk can use to intercept all overflows, including unsigned. I added some testcases so we don't break anything. Also included is another patch from David for += and friends. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68267 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-01Pull clang-cc code for generating PTH files based on the input type.Daniel Dunbar
- <rdar://problem/6741594> [pth] don't abuse -x to drive pth generation - Simpler, and fixes PR3915. Cleanup test cases for PTH: - Update to use -emit-pth - Removed PTH test of carbon.c and cocoa.mm; these didn't actually verify anything, and since PTH is token based the extra coverage (over cocoa.m) isn't particularly helpful. - Split PTH tests in cocoa.m to cocoa-pth.m, solely to increase available parallelism when running tests. Ted, could you update the PTH test cases (include-pth.c and cocoa-pth.m) to have some sort of positive check that the PTH is getting used? "# of PTH cache hits" or "tokens read from PTH cache" statistics would work great. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68189 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-01Add '-emit-pth' option to clang-cc as an alternate API for the high-level driverTed Kremenek
to generate PTH files. Soon we will remove from clang-cc the GCC-style '-x c-header' interface for generating PTH files and push this logic to 'clang'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68164 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-31(LLVM up) Update to use llvm::sys::getHostTriple().Daniel Dunbar
- Always pass -triple to clang-cc (-arch will be removed). - clang-cc doesn't play guess work with the target triple anymore. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68119 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-30Driver: Support -M and -MM.Daniel Dunbar
- Not particularly elegant, but my hand is forced by gcc. Also, tweak -ccc-print-bindings output. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68027 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-30Improve dependency file support.Daniel Dunbar
- Rip out various bits of logic from clang-cc's dependency file gen, force driver to provide instead. - -MD output now goes to proper location <rdar://problem/6723948> clang -MD puts dep file in /tmp with wrong name - -M and -MM still don't work correctly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68022 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-29Push DeclGroup much farther throughout the compiler. Now the variousChris Lattner
productions (except the already broken ObjC cases like @class X,Y;) in the parser that can produce more than one Decl return a DeclGroup instead of a Decl, etc. This allows elimination of the Decl::NextDeclarator field, and exposes various clients that should look at all decls in a group, but which were only looking at one (such as the dumper, printer, etc). These have been fixed. Still TODO: 1) there are some FIXME's in the code about potentially using DeclGroup for better location info. 2) ParseObjCAtDirectives should return a DeclGroup due to @class etc. 3) I'm not sure what is going on with StmtIterator.cpp, or if it can be radically simplified now. 4) I put a truly horrible hack in ParseTemplate.cpp. I plan to bring up #3/4 on the mailing list, but don't plan to tackle #1/2 in the short term. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68002 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-28Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for aChris Lattner
pointer. Its purpose in life is to be a glorified void*, but which does not implicitly convert to void* or other OpaquePtr's with a different UID. Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>. Change the entire parser/sema interface to use DeclPtrTy instead of DeclTy*. This makes the C++ compiler enforce that these aren't convertible to other opaque types. We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc, but I don't plan to do that in the short term. The one outstanding known problem with this patch is that we lose the bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to bitmangle the success bit into the low bit of DeclPtrTy. I will rectify this with a subsequent patch. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67952 91177308-0d34-0410-b5e6-96231b3b80d8
