Summary: @public
First diff to give better language information in the frontend.
This information is necessary to understand when 'self' is objc keyword,
when 'this' is C++ keyword and when they are not.

Summary: @public
qual_type was the same as type_ptr, so it was removed.
This commit makes it compatible with facebook-clang-plugins
Commands ran:
codemod --extensions ml,mli 'qual_type' 'type_ptr'
codemod --extensions ml,mli 'qt' 'tp'
If there is any other popular name for qual_type, let me know

Summary: @public
We no longer rely on existence of qt_raw field.
Update facebook-clang-plugins so that this field
is not even exported. This should give us some perf wins
since qual_type is written in a lot of places

Summary:
Using the qualified names of fields to create mangled names.
This removes the need to search for the fields in the tenv when translating a field access.
That was only done to build the correct mangled name,
The rest of the changes are using the qualified names for ivars and property names in the property module,
which is needed to make it work. Basically a big chain of changes of using qualified names to make the code
compile.
Summary:
This diff aims at removing the occurrences of the types in string form so that we can remove them
from the ast which will save space.
There is one occurrence left regarding attributes that will be handled later by Andrzej.
We build a function to create a string out of a function type used for name mangling.
Summary:
frontend and backend assume that Sil.Struct
doesn't have methods nor inheritance. In order to plug C++
classes we probably need them to be Sil.Class
Summary:
C function names depend only on their name (and their file is they are static, and their type if we are in C++)
This is more in sync with the actual semantics of C function names than the previous implementation.
Summary:
Make infer run with clang 3.7.0. Small changes are due to differences
in output of clang
NOTE: this diff will require recompiling clang (it takes time)
Summary:
Pass inheritance information to the backend
It also changes some functions in cTypes_decl and we are using type and decl maps to resolve these types
Summary:
This is the second of 3 stack diffs to deal with replacing the parser of types.
This diff is about changes to translate record types, as well as class types and enum
types. For class types and enum types we store the declaration pointer in the map of
types to find the type easier later.
For record declarations, we change the way we build record names.
Moreover, we don't translate typedefs anymore, because when we have a pointer to a typedef,
we can find the actual type it points to.
Summary:
This is the second of 3 stack diffs to deal with replacing the parser of types.
This diff is about general changes to the frontend to make it cope with the change. There
are two main challenges:
1. We create pieces of ast in ast_expressions, such as getters and setters. For that we create
custom types.
2. We store types in cMethod_signature for parameters and return type of functions. This was
stored as strings, but that means losing the pointer information which is vital to get the
sil types.
So this diff consists mostly of dealing with these challenges. It change the signature of
cMethod_signature and update modules accordingly.
To deal with the custom types, we build methods in ast_expressions for creating those types,
with a custom type pointer, like "internal_typeint". At the beginning of the translation we save
all these custom types in the map from type pointers to sil types that we build as we compute the
types, so that they are available later.
Another custom type that we build is a type of classes or pointer of classes based on the current
class. I found a simple way to deal with it, giving it a pointer "class_name", and then we know
how to translate those. Something I tried is to save the declaration of the current class and pass
that declaration around, but somehow that lead to pref regression, so I removed it in favor of this
more lightweight version.
Summary:
This is the first of 3 stack diffs to replace the parser of types in the clang frontend.
In this diff we remove the parser and the lexer and add a new module that does the
translation from ast types to sil types.
It is still incomplete, i.e. many c++ types are still not treated. However, all the
types that we were previously treating in C and ObjC are treated and some C++ ones, such
that the tests pass and we get good results in the apps.
Sometimes one needs to translate a record type when we havent translated the record itself,
so the translation of types and of records needs to be mutual recursive. I managed however
to get them into different modules and achieve the mutual recursion using higher order functions.
Summary:
each procedure has a different scope, so we can restart the fresh name generator and have more stable instructions in the cfg, that don't change when other procedures are changed
Summary:
Move proc_attributes to a separate module.
Field err_log, in common between proc desc and summary, can now be moved to ProcAttributes without creating cycles of dependencies.
Summary:
There's a lot of overlap between the representation of a proc desc and a spec summary. This diff moves all the data in common to the single record proc_attributes defined in Sil.
This gives a unified way of accessing most of the data carried by a procedure, whether it is contained in a proc desc or a spec. Also, it ensures that there is a single flow of information from proc desc to spec in the back-end, making sure that the information represented stays consistent.
Summary:
Use the new clang plugin that outputs biniou instead of Yojson. This binary format is more compact, which makes the frontend a little faster (5 to 10%).
@update-submodule: facebook-clang-plugins
Summary:
Use the map of pointers to find method declarations and build method signatures.
Remove the need for having an extra map for method signatures (and remove that map).
Summary:
see title. It will make number of arguments
less ridiculous and make it easier to share C/C++ structs.
Another diff that adds base class information for C++ will
follow.
This change is big enough to deserve separate diff
Summary:
Handle C++ method declarations and create cfgs for them.
Doesn't do:
Method calls (CXXMethodCall)
Using `this` expression in methods (including implicit ones)
Summary:
Refactor of creating method signatures. First step to use the map of pointers to find method declarations.
The idea is to have a function that creates a method signature from a declaration, later we can get the declaration from a pointer
and use this function to retrieve the method signature.

Summary:
Add basic translation for C++ `new` keyword.
Currently, it's modeled as simple `malloc` call.
Following constructs are still not working properly:
- array new `new [size_expr]`
- run initializer attached to `new` (such as `new int(5)`)
- `delete[]`
Summary:
1. Unify the code now that MemberExpr has more information available and it can be shared with ObjCIvarRefExpr
2. Use type from decl_ref instead of expression type. For methods, expression type is useless (`<bound something something`>). For fields it should be the same
Summary:
The methods in objc can have the same name in the same class, but one be instance and the other class,
so that we need to take the instance flag into account when defining unique names for ObjC methods.
Summary:
Update fcp version and make infer build with it.
It's not using new features yet, diffs will follow.
New stuff:
Proper type information in form of pointer->type
Expose more information about cxx classes (superclass info)
Add pointers to objc method decls when possible
Summary:
This commit is the result of
`find infer/src -name '*.ml' -or -name '*.mli' -exec ocp-indent -i \{\} \;`
and
`INFER_CHECK_COPYRIGHT=1 InferPrint`
Summary:
In preparation for C++ methods, we need to have type with
class, method, mangled (for overloading?)
1. Change objc method to support it
2. Do some renames to be less confusing
Summary:
In objC we already prefix field names with classes.
It's better to make it consistent since it'll allow
us to share more code between C++ and objC
Summary:
This adds support for having lookup from pointer to decl in C frontend
NOTE: with this diff atdgen 1.6 or later is required.
