2009-02-26Create a new TypeNodes.def file that enumerates all of the types,Douglas Gregor
giving them rough classifications (normal types, never-canonical types, always-dependent types, abstract type representations) and making it far easier to make sure that we've hit all of the cases when decoding types. Switched some switch() statements on the type class over to using this mechanism, and filtering out those things we don't care about. For example, CodeGen should never see always-dependent or non-canonical types, while debug info generation should never see always-dependent types. More switch() statements on the type class need to be moved over to using this approach, so that we'll get warnings when we add a new type then fail to account for it somewhere in the compiler. As part of this, some types have been renamed: TypeOfExpr -> TypeOfExprType FunctionTypeProto -> FunctionProtoType FunctionTypeNoProto -> FunctionNoProtoType There shouldn't be any functionality change... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65591 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-25Add experimental logic in GRExprEngine::EvalEagerlyAssume() to handleTed Kremenek
expressions of the form: 'short x = (y != 10);' While we handle 'int x = (y != 10)' lazily, the cast to another integer type currently loses the symbolic constraint. Eager evaluation of the constraint causes the paths to bifurcate and eagerly evaluate 'y != 10' to a constant of 1 or 0. This should address <rdar://problem/6619921> until we have a better (more lazy approach) for handling promotions/truncations of symbolic integer values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65480 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-25C99 DR #316 implies that the function parameter types that are knownDouglas Gregor
only from a function definition (that does not have a prototype) are only used to determine the compatible with other declarations of that same function. In particular, when referencing the function we pretend as if it does not have a prototype. Implement this behavior, which fixes PR3626. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65460 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24PTH: Cache *un-cleaned* spellings for literals instead of cleaned spellings.Ted Kremenek
This allows the PTH file to stay 100% in fidelity with the source code and defines away some weird cosmetic bugs for operations such as '-E' where maintaining knowledge of the original literal representation is useful. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65361 91177308-0d34-0410-b5e6-96231b3b80d8
2009-02-24PTH: When emitting tokens for literals with cached spellings, change the tokenTed Kremenek
size to that of the *cleaned* spelling. This way 'getSpelling()' for literals in the Preprocessor just works and doesn't read beyond the bounds of the cached spelling buffer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65354 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-19fix a bug introduced in my previous patch: moving clang headers to theChris Lattner
"after" group instead of the system group makes it so #include <limits.h> picks up the *system* limits.h file before clang's. This causes a failure on linux and is definitely not what we want. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@65026 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-16Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow.Daniel Dunbar
- Define pow[lf]?, sqrt[lf]? as builtins. - Add -fmath-errno option which binds to LangOptions.MathErrno - Add new builtin flag Builtin::Context::isConstWithoutErrno for functions which can be marked as const if errno isn't respected for math functions. Sema automatically marks these functions as const when they are defined, if MathErrno=0. - IRgen uses const attribute on sqrt and pow library functions to decide if it can use the llvm intrinsic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64689 91177308-0d34-0410-b5e6-96231b3b80d8

2009-02-14Patch by Ben Laurie:Ted Kremenek
ConstraintManager: - constify getSymVal() BasicConstraintManager: - Pull out logic that would be common to ConstraintManagers of a similar nature and put them in a parent class called 'SimpleConstraintManager'. RangeConstraintManager: - Added a new prototype ConstraintManager to track ranges of variables! This ConstraintManager keeps tracks of ranges of concrete integers that a symbolic integer may have. AnalysisConsumer: - Add driver option to use RangeConstraintManager with GRExprEngine-based analyses. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@64558 91177308-0d34-0410-b5e6-96231b3b80d8
