2009-04-14PCH support for a few very, very simple kinds of expressions. Hook upDouglas Gregor
expression (de-)serialization for VLAs, variable initializers, enum constant initializers, and bitfield widths. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69075 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-14When writing a PCH file, keep track of all of the non-static,Douglas Gregor
non-inline external definitions (and tentative definitions) that are found at the top level. The corresponding declarations are stored in a record in the PCH file, so that they can be provided to the ASTConsumer (via HandleTopLevelDecl) when the PCH file is read. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69005 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Partial PCH support for FileScopeAsmDecl and BlockDecl. Both requireDouglas Gregor
expression or statement serialization before we can test them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69002 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13PCH support for record decls/types and their fields. Now that we canDouglas Gregor
handle the definition of __builtin_va_list on x86-64, eliminate the forced -triple in PCH tests to get better coverage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68988 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-13Introduce PCH (de-)serialization for most compound types, excludingDouglas Gregor
Objective-C types and record types for the moment. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68984 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Add PCH support for enumerations and enumerators.Douglas Gregor
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68974 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Make the reading of the line table from a PCH file more robust againstDouglas Gregor
the unlikely event that the filename IDs in the stored line table end up being different from the filename IDs in the newly-created line table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68965 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-13Include the SourceManager's line table in the PCH file. We can nowDouglas Gregor
properly cope with #line directives in PCH files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68963 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-11now that we have an identifier table in the PCH file, finish hooking upChris Lattner
macro deserialization. We now correctly install II's in tokens, handle function-like macros, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68882 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-11add some #includes for better compatibility with gcc 4.4,Chris Lattner
thanks to Tobias Stadler for pointing this out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68868 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-11Store unique IDs for identifiers in the PCH file. Use some bitmanglingDouglas Gregor
so that we only need to perform the lookup and identifier resolution once per identifier in the PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68846 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10Compare the predefines buffer in the PCH file with the predefinesDouglas Gregor
buffer generated for the current translation unit. If they are different, complain and then ignore the PCH file. This effectively checks for all compilation options that somehow would affect preprocessor state (-D, -U, -include, the dreaded -imacros, etc.). When we do accept the PCH file, throw away the contents of the predefines buffer rather than parsing them, since all of the results of that parsing are already stored in the PCH file. This eliminates the ugliness with the redefinition of __builtin_va_list, among other things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68838 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10do a dance with predefines, and finally enable reading of macros fromChris Lattner
PCH. This works now, except for limitations not being able to do things with identifiers. The basic example in the testcase works though. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68832 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-10add support for reading macros. This does all the reading (with a bunch ofChris Lattner
fixme's, e.g. for tokens with identifiers) but does not actually install them. Some details with the predefines buffer needs to be sorted out first. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68828 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-10Implement serialization/deserialization of LangOptions in the PCHDouglas Gregor
file. When de-serializing LangOptions, we check that the currently-provided language options are consistent with the options used to compile the PCH file. If they are not, we emit a diagnostic and ignore the PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68820 91177308-0d34-0410-b5e6-96231b3b80d8

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

2009-04-02Also "flatten" PathLocations fed to the HTMLDiagnosticClient. We need a betterTed Kremenek
long-term strategy, but this should work for now. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68297 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-02Hack: Add 'PathDiagnostic::flattenLocations()'. Because PlistDiagnosticClientTed Kremenek
can use a PathLocation after any reference Stmts are reclaimed, flattenLocation() converts those references to statements to source ranges. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68292 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-16Build system changes to use TableGen to generate the variousDouglas Gregor
diagnostics. This builds on the patch that Sebastian committed and then revert. Major differences are: - We don't remove or use the current ".def" files. Instead, for now, we just make sure that we're building the ".inc" files. - Fixed CMake makefiles to run TableGen and build the ".inc" files when needed. Tested with both the Xcode and Makefile generators provided by CMake, so it should be solid. - Fixed normal makefiles to handle out-of-source builds that involve the ".inc" files. I'll send a separate patch to the list with Sebastian's changes that eliminate the use of the .def files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67058 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-13implement a new -fprint-source-range-info option, whichChris Lattner
defaults to off. When enabled, it emits range info along with the file/line/col information for a diagnostic. This allows tools that textually parse the output of clang to know where the ranges are, even if they span multiple lines. For example, with: $ clang exprs.c -fprint-source-range-info We now produce: exprs.c:21:11:{21:12-21:13}: warning: use of unary operator that may be intended as compound assignment (+=) var =+ 5; // expected-warning {{use of unary operator that may be intended as compound assignment (+=)}} ^~ exprs.c:22:11:{22:12-22:13}: warning: use of unary operator that may be intended as compound assignment (-=) var =- 5; // expected-warning {{use of unary operator that may be intended as compound assignment (-=)}} ^~ exprs.c:36:13:{36:3-36:12}: error: assignment to cast is illegal, lvalue casts are not supported (float*)X = P; // expected-error {{assignment to cast is illegal, lvalue casts are not supported}} ~~~~~~~~~ ^ exprs.c:41:4:{41:3-41:4}: error: called object type 'int' is not a function or function pointer X(); // expected-error {{called object type 'int' is not a function or function pointer}} ~^ exprs.c:45:15:{45:8-45:14}{45:17-45:24}: error: invalid operands to binary expression ('int *' and '_Complex float') P = (P-42) + Gamma*4; // expected-error {{invalid operands to binary expression ('int *' and '_Complex float')}} ~~~~~~ ^ ~~~~~~~ exprs.c:61:7:{61:16-61:22}: error: invalid application of '__alignof' to bitfield R = __alignof(P->x); // expected-error {{invalid application of '__alignof' to bitfield}} expected-warning {{extension used}} ^ ~~~~~~ Note the range info after the column in the initial diagnostic. This is obviously really annoying if you're not a tool parsing the output of clang, which is why it is off by default. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66862 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-12PathDiagnostics:Ted Kremenek
- PathDiagnosticControlFlowPiece now consists of a "start" and "end" location to indicating the branch location and where the branch goes. BugReporter: - Updated BugReporter to construct PathDiagnosticControlFlowPiece objects with "end" locations. PlistDiagnostics: - Plists now contain the bug "type" (not just bug "category") - Plists now encode control-flow pieces differently than events; now the "start" and "end" locations are recorded git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66818 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Extend the notion of active template instantiations to include theDouglas Gregor
context of a template-id for which we need to instantiate default template arguments. In the TextDiagnosticPrinter, don't suppress the caret diagnostic if we are producing a non-note diagnostic that follows a note diagnostic with the same location, because notes are (conceptually) a part of the warning or error that comes before them. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66572 91177308-0d34-0410-b5e6-96231b3b80d8
