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:
See D2465673, replacing `-gmodule` with equivalent flags, as per http://reviews.llvm.org/D11958
The `-fmodule-format` is not available on Xcode's clang, so skip it for now.
Summary:
In the new clang the parameters to these functions have notnull annotations, because of that infer tests fail. More concretely, the tests say there would be a memory leak. In the symbolic execution of those functions though, an inconsistency is created, because the parameter was nil, and the constraint argument should not be nil was also there, which leads to an error in the execution and no object is created, hence, no memory leak.
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:
`get_resource_or_undef` attribute is weird and was causing problems for me in another diff.
This diff refactors the attribute categories to make resource and undef separate.
Summary:
Harness generation was using the autogenerated harness file as the source file,
but placing the harness code in the cfg belonging do a different source file. Fix this confusion
by using the source file of the cfg containing the harness code throughout.
Summary:
The python parser for '-d <dir>' interpreted '-deprecation'
as '-d eprecation', which is not desirable. Fixed it by teaching the parser to
parse '-deprecation' as a boolean flag.
Summary:
Some build systems compile files both under the project root and under temporary
directories (e.g., /tmp), so there need not be a single project root. Just use absolute paths
in the case that we can't resolve a relative path from the project root.
Summary:
Added two annotations @TrueOnNull and @FalseOnNull to be used for boolean functions to specify what value is returned when the argument is null.
Added model for TextUtils.isEmpty, which corresponds to the annotation
@TrueOnNull
static boolean isEmpty(@Nullable java.lang.CharSequence s)
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:
System.getProperty can return null when the property is not found, and expects a non-null argument.
Add models for Infer and Eradicate to reflect that.
Summary:
Fix the issue with Linux, introduced in 721cc1957c and temporarily fixed in aef13134bf
Now clang gets the `x86_64-apple-darwin14` target only when running on ObjCXX source code with a specific `isysroot` flag.
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
