8f46673649 Add member designator parser 
A member designator is the second argument to the C offsetof() macro.

b43e2094ff typename: split lexer out into a separate module 
It will be used for parsing member designators next.

10cf1097b5 program: fix mypy errors regarding array rvalues 
We don't support array rvalues, so just add some asserts.

f299bea98a type/typeindex: implement saner typing for EnumType 
This is a big change that makes EnumType have a compatible integer type
member instead of copying the fields, which ends up touching a lot of
stuff but also fixing a bunch of static typing errors.

80df521452 type: handle some type errors caused by optional members 
I don't know why mypy suddenly started warning about these where it
didn't before, but they're real bugs.

07bcded124 typename: fix some harmless type errors 
These aren't actual bugs, but silence mypy anyways.

0a089e6ac9 cli: add history and tab completion 
rlcompleter won't complete getitem or any function calls, so that can be
improved upon, but this is already much better than nothing.

35271231fe program: swap ProgramObject arguments 
type, address, value makes more sense and looks more like C.

9560b913f3 typeindex: change Type.unqualified() to TypeIndex.operand_type() 
Converting an lvalue to an operand has to do a little bit more than
remove qualifiers:

- Convert array types to pointer types
- Convert function types to pointer types
 2018-05-06 21:29:59 -07:00

987f9be6db type: add Type.is_arithmetic() and Type.is_integer() 
This will be used for ProgramObject operators as a shortcut for
isinstance(type.real_type(), (ArithmeticType, BitFieldType).

bad1ab23b0 typeindex: add TypeIndex.array() 
Similar to TypeIndex.pointer(), just constructs an array type.
 2018-05-03 23:21:53 -07:00

b921d884df program: add ProgramObject.address_of_() 
Basically the "&" operator in C.

18e5e8f9bf typeindex: move easy types into base TypeIndex class 
Some types don't actually have to go through find_dwarf_type(), so they
can be handled in the common code. This allows us to add a MockTypeIndex
to the tests.

3cc11f3f5e typeindex: rename usual_arithmetic_conversions() to common_real_type() 
It doesn't actually do the conversion, it just finds the common type.
While we're here, don't make the types unqualied; the caller should do
that.
 2018-05-02 23:36:39 -07:00

928048be97 tests: use mocked TypeIndex for type conversion tests 
Instead of a real DwarfTypeIndex.

4891a6341f typeindex: add method for getting type of literal 
This will be used for ProgramObject operators where one operand is not a
ProgramObject.

b060c9dcf7 typeindex: make sure we can find base types 
The compiler might call a base type by any variation of its name (e.g.,
long or long int). Make sure we find it no matter what it chose.

90f6913242 program: convert value when creating rvalue 
This is useful for a few cases:

- We should make sure that the value of an object is actually valid for
  its type
- When casting, the value should be converted to the new type where
  appropriate
- For the upcoming ProgramObject operators

c3dbe939ad program: fix Program.object() type annotation 
It can also be used to create rvalues, so make the address optional.

812951c340 type: add Type.convert()

68462da720 typeindex: add usual arithmetic conversions 
The rules are really subtle and not completely specified, so hopefully
this covers all of the corner cases... This will be used for
ProgramObject operators.
 2018-05-01 00:17:20 -07:00

78a745588a type: add TypedefType.real_type() 
Instead of open-coding it in ProgramObject.

types.

80d3058b17 type: canonicalize basic type names

consistent with naming.

e1673f9f29 typename: use a better canonical formatting for integer types

322b35259b program: better error message for ProgramObject.__getattr__() on non-struct
