Aaron Tomb **20100127172548 The previous patch to add support for transparent unions broke type checking of paramters to functions passed via function pointers. If a function was defined to take a parameter that was a typedef name, and you passed in a function in which the matching parameter was the raw type referred to by that typedef, the two would not match because the type checker was failing to dereference typedef names in this one case. ] [Support a bunch of additional GCC builtins.

Aaron Tomb **20091222182008 Modify the types in Language.C.Syntax.AST to be parameterized by an annotation type. The parser returns ASTs annotated with NodeInfo, but other analysis code can replace the annotations. The parametric AST types have longer, less abbreviated names. For instance, statements are now data CStatement a = ... with a type synonym type CStat = CStatement NodeInfo ] [Extend NodeDerive.hs to deal with parametric AST benedikt.huber@gmail.com**20091220235521 Ignore-this: b9783b5f32e559597151eb96b3d5ff2c ] [.cabal: recognize separate syb marco-oweber@gmx.de**20091130231738 Ignore-this: 9e0ec55119d163b9d4e439e8d3ee16de ] [Arrays can participate in subtraction. Aaron Tomb **20091112193809 Previously, subtraction was allowed on pointers but not arrays. This might be better implemented by coercing arrays to pointers beforehand, but this works, and is easier at the moment. Eventually, it might be best to refactor the type checker a bit to support array->pointer coercion in the right places. ] [Export isTypeDef Aaron Tomb **20091112193721] [Add __builtin_clz Aaron Tomb **20091112193654] [Change pretty-printing of the else branch, s.t. the braces get on a new line benedikt.huber@gmail.com**20091101230141 Ignore-this: a9946733e17d2fefcee4c0bcb46d42b6 ] [Fix awkward array type checking. Aaron Tomb **20090927200632 Array type checking was somewhat broken before. During a moment of frustration (because some key type checking code was incorrect), I decided to convert array types to pointer types immediately after getting them out of the symbol table, to simplify type checking. Unfortunately, this meant that the types returned by tExpr were never array types, even when they should be. The other bits of the type checker are in much better shape now, so this egregious hack isn't necessary. ] [Use pattern matching instead of partial function Aaron Tomb **20090816213828 Some type checking code used the partial identOfName function in a case expression that was already pattern matching on the structure of VarName. It's shorter and safer to extract the field directly in this case. ] [Remove unused, buggy fieldOffset function. Aaron Tomb **20090816213737] [Replace CStorageSpec Show instance with Pretty instance Aaron Tomb **20090816185348 CStorageSpec had a Show instance specified in L.C.Syntax.AST, but no other data type did. This Show instance was only used in one place, and it seemed somewhat inconsistent with the rest of the code. So I removed the Show instance from L.C.Syntax.AST, added a Pretty instance in L.C.Pretty, and changed the one place that used the Show instance to use the Pretty instance instead. This could potentially cause incompatibilities with client code, but it's unlikely: how often does code need to render storage specifications as text but nothing else? Any broken code can be fixed with minimal effort. ] [Add constant expression evaluation. Aaron Tomb **20090802235355 This patch adds basic support for constant expression evaluation. Not all cases are handled yet: alignof is not implemented, and the values from the initializers for const globals are not yet used. This patch also enables proper type checking of the GCC extension __builtin_choose_expr, which depends on constant expression evaluation. ] [Tighten a bunch of class contexts. Aaron Tomb **20090725044519 The separation of MonadTrav into several smaller monads makes it possible to give more precise types to a number of functions. Many functions that previously included the MonadTrav class constrain now have one or both of MonadCError and MonadSymtab. They never need to generate fresh names or call 'handleDecl'. ] [Split MonadTrav into several monads Aaron Tomb **20090724011254 The MonadTrav class serves several purposes, and some useful functions only need some of its available methods. This patch splits it into several monads: * MonadName, for fresh name generation. * MonadSymtab, for symbol table operations. * MonadCError, for C-specific error handling. * MonadTrav, combining all of the above, plus a callback function. ] [Refactor type checking a bit. Aaron Tomb **20090723012504 Now many of the utility functions in the type checker are pure functions, returning Left on error. Clients in the MonadTrav monad can use typeErrorOnLeft to turn these into "real" errors. ] [Export getUserState and tDesignator Aaron Tomb **20090716234346 The former is necessary for user state to be at all useful. The latter is usable outside of the core type checker, and I found it useful in at least one project, so it seems worth exporting. ] [Fix bug #29 for real now! And remove typeof from SemRep. Aaron Tomb **20090714035021 This patch fixes bug #29 for real, without the various breakage the previous patch caused. In addition, it allows the third example listed in my last patch to typecheck properly. This change makes it no longer necessary to have a representation for 'typeof' in SemRep, so this patch removes that, as well. ] [ Fix derive.sh and DeclEvent CNode instance (reported by Denis Bueno) benedikt.huber@gmail.com**20090712213037 Ignore-this: c601523dba6649a97bb927c452f80e13 ] [Further progress on bug #29 Aaron Tomb **20090620201202 Ignore-this: d2b78ed617dbd4c3d70df5a92e1e9e4e It's now possible to correctly type check this: typedef int ax25_dev; int f() { ax25_dev *ax25_dev, *ax25_dev_old; } and this: typedef int ax25_dev; int f() { typeof(ax25_dev) *ax25_dev, *ax25_dev_old; } but not this: typedef int ax25_dev; int f() { typeof(ax25_dev) *ax25_dev, *ax25_dev_old; typeof(ax25_dev_old) foo; } The second line resolves to ax25_dev, which now is an object, not a type. Is this valid ANSI C? GCC accepts it. ] [Add tests for bug #29. Aaron Tomb **20090228184609] [Record use/def link between names. Aaron Tomb **20090222200922 The DefTable type included a refTable field to record links between use and definition Names, but it was unused. Now, whenever analysis code calls lookupTypeDef or lookupObject, the link between use and definition is store in the refTable. Type checking should fully populate this table, because it needs to lookup all uses to ensure that their use is well-typed. ] [Only analyse TypeSpecs once. Fixes #29. Aaron Tomb **20090222183955 Previously, the type specifiers of declarations with multiple declarators were analyzed multiple times. However, when declaring a variable with the same name as a type, this causes problems. Consider: foo *foo, *bar; The analysis of "foo *foo" results in a symbol table where the innermost definition of "foo" refers to an object, not a typedef name. Therefore, when analyzing "foo *bar", the type checker tries to look up "foo" and gets an object declaration, which is a type error. Code like the above example does actually occur, and is valid C. The seemingly equivalent: foo *foo; foo *bar; is not valid C, and is rejected as it should be. The second line is seen as an expression statement, multiplying foo and bar, and fails because bar is not in scope. ] [Change examples to work with the new fileOfNode type sig. benedikt.huber@gmail.com**20090223113358 Ignore-this: 5659ff98882f2808062bc0f1927788f This change is somewhat preliminary, as the patch to Data.Position needs to be cleaned up. ] [Change fileOfNode to return (Maybe FilePath) instead of FilePath benedikt.huber@gmail.com**20090223113342 Ignore-this: 2577930de0523d87de2d54cf674c5de9 ] [Bump version number benedikt.huber@gmail.com**20090223113326 Ignore-this: eeb0bc1e75401e74993da85ead1e6954 ] [Better and (hopefully) correct examples for initializer list benedikt.huber@gmail.com**20090212123709 Ignore-this: a97ad65cf2a643ae9d5db8cf6789d4f3 ] [Improve README in test/harness benedikt.huber@gmail.com**20090126170411 Ignore-this: debc7f4d7c7215ecca631e1506aa5024 ] [Docuementation for 'position' and 'type PosLength' benedikt.huber@gmail.com**20090126164856 Ignore-this: 1b97e03544f85c929ef9b25e8bed039 ] [Documentation for Position selectors benedikt.huber@gmail.com**20090126164833 Ignore-this: d7f58d4fed2a7f994f4f854498d3c381 ] [[Lexer] use incOffset joe.thornber@gmail.com**20090126152422] [[Position] add incOffset joe.thornber@gmail.com**20090126152403] [[Position, Lexer] resolve conflicts joe.thornber@gmail.com**20090126151257] [[Position] documentation joe.thornber@gmail.com**20090126095411] [[Position, Lexer] Don't export any constructors for Position joe.thornber@gmail.com**20090126094323 Instead use the provided operators to query/update a position.

For example, we now accept: struct baz { int a; union { int b; int c; }; } v = { .a = 0, .b = 1 }; and struct foo { int x; struct bar { int y; } inner; } z = { .x = 0, .inner.y = 1 }; ] [Allow void functions to return void expressions Aaron Tomb **20081205235436 There really is code (in Linux) that looks like this: void g(); void f() { return g(); } The standard doesn't allow it (6.8.6.4.1) but GCC does, so it seems useful to allow it ourselves, too. Eventually, it would make sense to have some configuration settings that describe exactly which variant of the language to accept. In strict C99 mode, we'd reject this. ] [Include anonymous structure members in analysis Aaron Tomb **20081205235158 When typechecking structure declarations, we previously skipped anonymous members.

Aaron Tomb **20081202175734 This patch undoes my previous "fix" of getSubStmts and does things properly inside getLabels, instead. Now, function-scope labels are all added before we start type checking the function, and local labels are added when entering the block they live in. Ultimately, the utility functions getSubStmts, compoundSubStmts, and getLabels probably belong somewhere in the Language.C.Syntax.* hierarchy. ] [Change block scopes to create new label scope, too. Aaron Tomb **20081202175442 This makes local labels work out properly. We should scan a function body for non-local labels and add them all inside the initial function scope, anyway, since labels can jump backward, so this shouldn't cause any problems. ] [Remove typeof from field types.
