2007-11-29Removed potential buffer overrun (spotted by Neil Booth) when ↵Ted Kremenek
NumericLiteralParser converts a parsed literal into an APFloat. We are still performing a copy of the string, which hopefully will be removed eventually for performance reasons. This version now is at least safe. Changed rounding in APFloat construction in NumericLiteralParser from rmTowardsZero to rmNearestTiesToEven. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44422 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Several fixes/simplifications surrounding how we stream top-level decl AST's.Steve Naroff
The following code... typedef struct cssm_data {} CSSM_DATA, *CSSM_DATA_PTR; struct Y { int A; }; struct X { int A; } D; struct X E, F; ...now produces the following output... > ../../Debug/bin/clang xx.c -ast-print Read top-level tag decl: 'cssm_data' typedef struct cssm_data CSSM_DATA; typedef struct cssm_data *CSSM_DATA_PTR; Read top-level tag decl: 'Y' Read top-level tag decl: 'X' Read top-level variable decl: 'D' Read top-level variable decl: 'E' Read top-level variable decl: 'F' ...which is much more accurate than the previous -ast-print output... typedef struct cssm_data CSSM_DATA; typedef struct cssm_data CSSM_DATA; Read top-level variable decl: 'D' Read top-level variable decl: 'E' Read top-level variable decl: 'E' git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44421 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Converted AST Pretty-Printer to use iostreams instead of FILE*. This fixesTed Kremenek
a bug where the statement pretty-printer used iostreams but the AST printer did not. This was an issue when dumping ASTs to something other than stderr. Updated SerializationTest to use the new iostreams interface for the AST printer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44417 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Inlined test case to make it independent of the stmt_exprs test case in ↵Ted Kremenek
test/Sema. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44416 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Added the "Serialization" test directory to the set of tests executed.Ted Kremenek
Introduced a few line breaks to make the Makefile easier to read. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44413 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Added initial test case for testing serialization of ASTs. This testTed Kremenek
case simply performs --test-pickling on the code found in Sema/stmt_exprs.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44412 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Modified --test-pickling to perform an actual cross-check of serialized ASTs:Ted Kremenek
(1) Parsed ASTs are pretty-printed to a text file. (2) The ASTs are serialized to disk. (3) The ASTs are deserialized from disk. (4) The deserialized ASTs are pretty-printed to a text file. (5) The two pretty-printed files are compared. If they are different, the test fails. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44411 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Changed TestRunner.sh to dump the output and generated script files inTed Kremenek
subdirectories mirroring where the test case file is located For example, for the test case "Sema/stmt_exprs.c", instead of the files "Output/stmt_exprs.c.out" and "Output/stmt_exprs.c.out.script" being created, the files "Output/Sema/stmt_exprs.c.out" and "Output/Sema/stmt_exprs.c.out.script" are created. This prevents any collisions from different test directories that have the same file name for a test case, and also makes it clear where the test case was drawn from. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-28Added missing "RUN:" to comment for test case file. This fixed a bug where ↵Ted Kremenek
the test case testing the frontend's support of statement expressions was not being executed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44409 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-27Migrated static functions that print decls into a DeclPrinter class,Ted Kremenek
which is now used (or subclasssed) by the ASTConsumers. This new class stores a FILE* that is used for writing, instead of just hardwiring output to stderr (it defaults to stderr if no FILE* is provided). Modified CreateASTPrinter() to accept a FILE* for printing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44377 91177308-0d34-0410-b5e6-96231b3b80d8

Sema::CheckSingleInitializer/ActOnCallExpr/CheckMessageArgumentTypes/ActOnReturnStmt to Sema::CheckSingleAssignmentConstraints. This makes sure all null pointer assignments are considered compatible. Thanks to Seo Sanghyeon for the bug, follow-through, and patch! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44366 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44349 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-26Added optional pass-by-reference argument "isExact" toTed Kremenek
NumericLiteralParser::GetFloatValue(). Upon method return, this flag has the value true if the returned APFloat can exactly represent the number in the parsed text, and false otherwise. Modified the implementation of GetFloatValue() to parse literals using APFloat's convertFromString method (which allows us to set the value of isExact). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44339 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-26Fixed StmtPrinter to handle GCC extension to the ternary operator "?:" whereTed Kremenek
the LHS subexpression can be NULL. Patch provided by Nuno Lopes! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44328 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-26Fixed bug in CFG construction where we did not properly handle the GCCTed Kremenek
extension "?:" for the ternary operator, e.g.: x ?: y; This expression is represented in the clang ASTs as a ConditionalOperator whose LHS expression is NULL. Now we handle this special case, causing the block containing the condition to be a predecessor to the block that "merges" the values of the ternary operator. Thanks to Nuno Lopes for identifying and diagnosing this bug! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44327 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-24Fixed bogus culling of uninitialized-values "taint" propagation during ↵Ted Kremenek
assignments. We accidentally were throttling the propagation of uninitialized state across assignments (e.g. x = y). Thanks to Anders Carlsson for spotting this problem. Added test cases to test suite to provide regression testing for the uninitialized values analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44306 91177308-0d34-0410-b5e6-96231b3b80d8
