bcc's Issues

Using "void"-functions as arguments leads to "Illegal expression type"

SuperStrict
Framework Brl.StandardIO

'no return value!
Function a(i:Int)
End Function

Function b:Int()
    Return a(1) - a(2)
End Function

b()

Fails with "Illegal expression type" on the Return a(1) - a(2)_ call. On Vanilla it compiles and would return "0".

[emscripten] Too many setjmps in function

A Try/Catch inside a loop can generate the following runtime error :

too many setjmps in a function call, build with a higher value for MAX_SETJMPS

Current code looks like this :

do {
    jmp_buf * buf = bbExEnter();
        switch(setjmp(*buf)) {
        case 0: {

Perhaps pushing setjmp(*buf) into a separate bbExXXXX() function and returning the result would fix this?

Functionpointer to static Function

This example should output "Hello World":

Superstrict

(New B).Init()

Type A
    Function NestedA()
        Print "Hello World"
    End Function
End Type

Type B
    Method Init()
        Self.InitPointer(A.NestedA)
    End Method
    Method InitPointer(A())
        A()
    End Method
End Type

It is passed through bcc correctly (i.e. bcc[ng] dosn't throw an error).
The original bcc compiles this example as expected.
bcc[ng] however generates c-code that generates the following gcc error:

/home/octavian/Programmierung/bmax/test/.bmx/classFunctionpointer.bmx.console.debug.linux.x86.c:25:113: error: ‘struct BBClass__classFunctionpointer_B’ has no member named ‘fn_NestedA’
  ((struct _classFunctionpointer_B_obj*)o)->clas->md_InitPointer(o,((struct _classFunctionpointer_B_obj*)o)->clas->fn_NestedA);

It should however search in struct _classFunctionpointer_A_obj for fn_NestedA.

Call to Var argument with Var variable should pass as pointer.

In the following code, the call to level2(num) is generated incorrectly by adding a pointer dereference to the argument - rather than passing it through as the original pointer.

SuperStrict

Framework brl.standardio

Local i:Int

level1(i)

Print i

Function level1(num:Int Var)
    level2(num)
End Function

Function level2(num:Int Var)
    num :+ 10
End Function

Multidimensional Arrays [ , ] not working

While testing the new if-handling I recognized that the following line is not working:

(prime.mod/libb3d.mod/libb3d.bmx)

Type TVRTSChunk Extends TChunk
...
    Field tex_coords#[,][]

UTF8? Char appears in MaxIDE but not other Texteditors -> compiler stops

I have this piece of code in a UTF8-encoded source file:
(direct copy paste)

    Function Create:TElevatorSoundSource(_movable:Int)
        Local result:TElevatorSoundSource  = New TElevatorSoundSource
        result.Movable = _movable

When compiling in MaxIDE it opens up the file and the line containing the error has some odd char appended:

    Function Create:TElevatorSoundSource(_movable:Int)
        Local result:TElevatorSoundSource  = New TElevatorSoundSource
        result.Movable = Â_movable

As GitHub allows other character displays, I added a screenshot to show up what is displayed there:

Maybe the parser should ignore "invalid" characters at all?

More interesting: The whole file compiles with vanilla BMX ... so this might skip such "utf8"-char thingies already.

Unable to find overload for ListFromArray(String[]).

Somehow ListFromArray(stringArray) does not compile

SuperStrict
Framework Brl.StandardIO
Import Brl.LinkedList

'does not work
Local arr:String[] = ["one", "two", "three"]
'works
'Local arr:Object[] = ["one", "two", "three"]

'ListFromArray wraps "TList.FromArray", passing an string[] array
'leads to a failing compilation
Local list:TList = ListFromArray(arr)
'somehow using it directly, does not fail
'Local list:TList = TList.FromArray(arr)

For Local s:String = EachIn list
    Print s
Next

Edit: interestingly this works when using TList.FromArray() directly - ListFromArray() is just a wrapper to it. Adjusted aboves sample code accordingly

Pointer problems...

Compiling:freetypefont.bmx

/BlitzMaxNG/mod/brl.mod/tgaloader.mod/tgaloader.bmx<62> : Error : NULL

gnet.bmx line is:
If Not enet_host_service( _enetHost,ev,0 ) Return

freetypefont.bmx line is:
MemCopy slot,_face.glyphslot,SizeOf slot

tgaloader.bmx line is:
If stream.ReadBytes( hdr,8 )<>8 Return Null

stream.ReadBytes awaits (byte ptr, int)
-> If stream.ReadBytes( Varptr i,8 )<>8 Return Null
compiles fine.
Seems that pointer handling is not correct atm
enet_host_service awaits (Byte Ptr, Byte Ptr, int)
-> think it is the same problem
freetypefont: glyphslot is an "Int Ptr", maybe that it the flaw...

summing up Arrays of different types should return a mixed array

Another module complained about not being able to compile:
prime.mod/libms3d.mod/libms3d.bmx

It seems BlitzMax allows to "merge" arrays of different types and the result is an array containing both object arrays). But it does not allow "merging" two objects into an array automatically!

Sample code:

SuperStrict

Type Base
    Field name:string="Base"
End Type

Type Other
    Field name:string="Other"
End Type


Function CollectObjects:int(obj:object[])
    print "got "+obj.length+" objects"
End Function


local baseA:Base = new Base
local baseB:Base = new Base
local otherA:Other = new Other
local otherB:Other = new Other

'does not work
'CollectObjects(baseA + baseB + otherA + otherB)

'does work
local bases:Base[] = [baseA, baseB]
local others:Other[] = [otherA, otherB]

CollectObjects(bases + others) 'prints 4

current code mentions a "TODO" in the balance-function for balancing two arrays.

Module not found when accessing (new MyType.property)

Type My
    Field valB:int[] = new Int[3]
End Type

'this line throws the compilation error:
print (new My.valB.length)

Compile Error: Module 'My.valB' not found

"unreachable" message when a function with ":returntype" does not return something

Code:

'function which does not return something by default
Function withReturn:int()
  if 1=1 then return True
End Function

translator.bmx:

    Method TransReturnStmt$( stmt:TReturnStmt )
        Local t$="return"
        If stmt.expr t:+" "+stmt.expr.Trans()
        unreachable=True
        Return t
    End Method

compilation result: "unreachable"

If no "return"-value is found, use "null" - or in the case of "non-objects" their "null"-equivalents (0, "").

Len() not working for numbers/number-variables

Currently "Len" is defined to accept objects, the "var" and "const"-expressions have set their types to "string" in the case of being compatible. This includes numbers - so numbers get some kind of "string" for code generation but not when calling "->length". Maybe split the following "if TStringType..." so it Returns "1" for numbers (or use a different expr.expr.exprType).

problematic part is:

    Method TransLenExpr:String(expr:TLenExpr)
        If TStringType(expr.expr.exprType) Then
            Return expr.expr.Trans() + "->length"
...

because "->length" is not available for len(1).

Sample (i could also create a test for it):

Framework brl.Standardio
Import Brl.LinkedList

local s:string = "Hello"
print Len(s) + " = 5"

local i:int = 100
print Len(i) + " = 1"

print Len("Hello") + " = 5"

local l:TList = CreateList()
print Len(l) + " = 1"

local a:int[] = new int[5]
print Len(a) + " = 5"

Error:

error: invalid type argument of â��->â�� (have â��BBStringâ��)
   brl_standardio_Print(bbStringConcat(bbStringFromInt(&_s3->length),&_s2));
                                                           ^

Means: "->length" is not known for this variable.

min/max in function with "var" params fails with "incompatible type for argument"

The following code does not compile:

SuperStrict

Framework Brl.StandardIO
Import Brl.Math

Global f:Float =  1.0
Global f2:Float =  0.2

'compiles
Print Min(f, f2)

'compiles
Function SortValues(valueA:Float, valueB:Float)
    Local newValueA:Float = Min(valueA, valueB)
    valueB = Max(valueA, valueB)
    valueA = newValueA
End Function

'compiles
Function SortIntValues(valueA:Int Var, valueB:Int Var)
    Local newValueA:Int = Min(valueA, valueB)
    valueB = Max(valueA, valueB)
    valueA = newValueA
End Function

'fails
Function SortFloatValues(valueA:Float Var, valueB:Float Var)
    Local newValueA:Float = Min(valueA, valueB)
    valueB = Max(valueA, valueB)
    valueA = newValueA

Invalid scope kind

When it came up to compile my "main.bmx" (containing a lot of imports - and many includes for the not-so-dependency-free code) I got an "internal error".

It errored on the line:
Local visibleFilters:TProgrammeLicenceFilter[] = New TProgrammeLicenceFilter[0] ' = TProgrammeLicenceFilter.GetVisible()
in the following piece of code (a file included in "main.bmx"):

        'only react to genre area if episode area is not open
        If openState <3
            If MOUSEMANAGER.IsHit(1) And THelper.MouseIn(genresRect.GetX(), genresRect.GetY() + genresStartY, genresRect.GetW(), genreSize.GetY()*TProgrammeLicenceFilter.GetVisibleCount())
                SetOpen(2)
                'error on the following line     
                Local visibleFilters:TProgrammeLicenceFilter[] = TProgrammeLicenceFilter.GetVisible()
                currentGenre = Max(0, Min(visibleFilters.length-1, Floor((MouseManager.y - (genresRect.GetY() + genresStartY)) / genreSize.GetY())))
                MOUSEMANAGER.ResetKey(1)
            EndIf
        EndIf

GetVisible returns an array of "TProgrammeLicenceFilter" objects, it is defined in another file (which gets imported).

Type TProgrammeLicenceFilter
    Global filters:TList = CreateList()
...
    Function GetVisible:TProgrammeLicenceFilter[]()
        local result:TProgrammeLicenceFilter[]
        For local f:TProgrammeLicenceFilter = EachIn filters
            if f.displayInMenu then result :+ [f]
        Next
        return result
    End Function
...

I tried to simulate it in a short code example, but there it works as expected.

So I have compiled bcc.debug with the commandline to compile my main.bmx:

Ideas how to narrow it down even more?

PS: When removing that GetVisible-Call, the next error is a similar portion of code (returning an other type of filter-objects) - so the scope of the call is different to the one before.

BCC cannot handle " ^ " (power of)

Utilizing the ^ char for a power-of-calculation results in an compilation error:

Error : Expecting expression but encountered '^'
or
Error : Syntax error - expecting ')'.
if used in a way like (bla + blubb)^2

-> will expand one of the numeric tests to make the tests fail until the bug is fixed

Overriding "no return value"-methods within modules

I just tried to compile maxmod again:

./bmk makemods -r -a maxmod2
Compiling:maxmod2.bmx
Compile Error: Overriding method does not match any overridden method.
[/BlitzMaxNG/mod/maxmod2.mod/maxmod2.mod/maxmod2.bmx;340;0]

The line is the following "Stop()" method:

Type TMaxModChannel Extends TChannel
...
    Method Stop()
        _channel.Stop()
    End Method

interestingly "TChannel" defines that method exactly the same (no explicit return value).

Changing it to "Stop:int()" in TChannel AND TMaxModChannel removes the error message (and goes on to the next :p).

So this means, bcc-ng currently seem to have problems with "void" methods in modules.
Doing the same in a single file works as expected, same for normal "file imports" (import "bla.bmx").

Invalid suffix ".0f" on floating constant

C error "Invalid suffix ".0f" on floating constant" with the following code:

    'returns whether two values are approximately the same
    '(1 and 1.00001 are identical, 1 and 1.1 not)
    Function areApproximatelyEqual:Int(a:Float, b:Float)
        '1E-06 is a value defining at which point things get equal
        '-> 5th digit after comma/point
        '1.121039E-44 is the smallest value
        Return Abs(b - a) < Max(1E-06 * Max(Abs(a), Abs(b)), 1.121039E-44)
    End Function

As replacing that values with "0.000001" and "2^(-146)" works ... I assume this a Bug because the compiler does not understand what kind of type this expressions are.

Assigning functionpointer to functionpointer array

    Method SetCharsEffectFunction(position:int, _func:TBitmapFontChar(font:TBitmapFont, charKey:string, char:TBitmapFontChar, config:TData), config:TData=null)

Local Variables

Need to rewrite local variable code to declare all those within a function block at the top/start of the function. This includes nested local variable declarations too (i.e. those within other block in the function).

This will allow easier integration with the debugger at a later stage as we will need access to their address on entry to the function.

Repeat-loop: cannot access method of returned class instance

    End Method

Function GetCollectionInstance:TCarCollection()

    return TCarCollection.instance
End Function

'FAILS too

'until GetCollectionInstance().AllCarsUpdated()


'WORKS
'here we use the global "instance"
'repeat
'   TCarCollection.GetInstance().Update()
'until TCarCollection.instance.AllCarsUpdated()

As soon as I create a instance manually and then use that directly

TCarCollection.GetInstance() 'create instance
repeat
    TCarCollection.GetInstance().Update()
until TCarCollection.instance.AllCarsUpdated()

it successfully compiles. So it seems returned instances of a type cannot access their methods in while/repeat-loops (bcc translates both to while).

Type property initialization with previous declared properties

During initialization of a field one cannot assign a value of another field of the same type.

Does not compile:

    Type EndingScene Extends T2DDynamicGameScene
...
        Field TEXTS_COUNT = 23
        Field Texts:String[TEXTS_COUNT]

Does compile:

    Type EndingScene Extends T2DDynamicGameScene
...
        Field TEXTS_COUNT = 23
        Field Texts:String[23]

accessing (new MyType.property) returns nothing

When accessing a property of a "newly" created type instance, the created C-code is not correct.

SuperStrict

Framework BRL.StandardIO

Type MyObject
    Field x:Int = 1
    Field y:Int = 2

    Method Init:MyObject(x:Int, y:Int)
        self.x = x
        self.y = y
        return self
    End Method
End Type

'nothing is printed (expected: 2)
print (new MyObject.y)

'20 is printed (expected: 20)
local obj:MyObject = new MyObject.Init(10,20)
print obj.y

C-File:

//print (new MyObject.y)
brl_standardio_Print(bbObjectDowncast(bbObjectAtomicNew(&_new_03_MyObject),&bbStringClass));

//local obj:MyObject = new MyObject.Init(10,20)
struct _new_03_MyObject_obj* bbt_obj=_new_03_MyObject.md_Init((bbObjectAtomicNew(&_new_03_MyObject)),10,20);

//print obj.y
brl_standardio_Print(bbStringFromInt(bbt_obj->__new_03_myobject_y ));

So you see: the direct-print just creates a new object instance but does not access the property at all.

"SizeOf"-implementation

As Bruce suggested that sizeOf has to get restructured.

I checked the current implementation, and the approach there is to distinguish by "objectusage -> object". So it first checks if the object is a constant, a variable, a function call etc.
We could reorder it in the way it checks for the the object first, and afterwards checks the usage type.

so we go from

if var
  if objectType...
  elseif numericType 
     genericImplementationFittingForAll()
  elseif arrayType...
  ...
elseif const
  if numericType 
    genericImplementationFittingForAll()
  elsif arrayType
  ...
endif

if objectType
  if var ...
  elseif membervar ...
  ...
elseif numericType
  genericImplementationFittingForAll()
endif

Sorry for this a bit confused representation of the approaches, but the idea of the second one is to avoid writing things multiple times. So you might end up with a bit shorter code only writing specific portions once - but this costs something: structure and overview. I think the current approach fits best and the only idea I can come up regarding "optimization" is to remove unneeded casts (when accessing field-properties TExpr already implements).

Another Idea is to implement a "SizeOf" for each "ExprType" so we just call an anonymous function GetSize() and it takes care of everything needed within the extended expressions.

Means TObjectType knows how to calculate its size, TStringType too. But for this the GetSize() needs to know about the parent to access that too. Dunno how a TStringType.GetSize(expr:TExpr) adds cyclic dependencies.

Ideas?

Creating and Assigning a multidimensional Array

DotDot right after symbol

The following code does not compile as it recognizes "Mod.." as single command and therefor expects a "identifier".

Local a:Int = 10
a:Mod..
10

Adding a space between Mod and DotDot then works as expected

Local a:Int = 10
a:Mod ..
10

I know that above is a really "constructed" example, maybe other things bug out similar to this.

"Super." in overridden functions leads to "Illegal use of super"

While trying to remove compilation errors in my game TVTower I come into contact with odd coding styles (happens when mixing function and methods :p).

Seems you cannot call "super" within a function of a type.

SuperStrict
Framework Brl.StandardIO


Type A
  Function call:Int()
  End Function
End Type

Type B Extends A
  'override
  Function call:Int()
   '"illegal call to super" while vanilla calls "call()" of
   'the type "A"
    Super.call()

   'of course this works as expected
   A.call()
  End Function
End Type

Functionpointer as method argument is interpreted as Overriding method.

Functionspointer as method arguments are interpreted as methods.
Easiest example to reproduce this error:

SuperStrict
Framework brl.blitz

Type Test
    Method t(compare:Int(obj1:Object, obj2:Object))
    End Method
End Type

What's expected:
compiling with bcc works.
What actually happens:
bcc thinks "compare" (the argument) shall override "Method Object.Compare:Int(Local otherObject:Object)"

More details:
I tried to compile wxWidgets with bcc and after fixing lots of bugs i stumbled upon this (wx.mod/wxlistctrl.mod/wxlistctrl.bmx line 819):

    bbdoc: 
    End Rem
    Method SortItems:Int(compare:Int(item1:Object, item2:Object, data:Object), data:Object)
        callback = compare
        callbackData = data
        Return bmx_wxlistctrl_sortitems(wxObjectPtr)
    End Method

I've extended bcc to show which alternative there is when the "Overriding method does not match any overridden method." error is thrown.

Last output of bcc (those two lines beginning with "Did" are the ones generated by my addition to bcc to debug this Problem):

Compiling:wxlistctrl.bmx
Did not find "Function compare:Int(Local item1:Object,Local item2:Object,Local data:Object)"
Did you possibly mean: "Method Object.Compare:Int(Local otherObject:Object)"?
Compile Error: Overriding method does not match any overridden method.

It seems like bcc thinks "compare" (the function pointer) shall be a method of wxListCtrl.

Function pointer assignment failing with params

Current bcc/bmk fails to compile sdl.mod/sdlgraphics.mod because of this line:

bmx_SDL_WarpMouseInWindow is defined in common.bmx:

Extern
    ...

End Extern

output of compiler:

Compiling:sdlgraphics.bmx
Compile Error: Missing function argument 'x'.

Seems bcc somehow thinks you want to assign the result function.

Same error bmx-ng/brl.mod#8.

[Co-Op] Documentation - Setup Instructions

Because the new TODO notes a better documentation and install instructions I will post my current state of the "bmx - setup" here.

Of course it includes more than just "bcc" so maybe we should create a "bmx" repo within "bmx-ng" to create something like "releases" there - and this release then include the complete documentation.

So if one of you feels brave enough we could try to improve the my sketch of an instruction file:

+===========================================+
| FIRST STEPS / MODULE COMPILATION          |
+===========================================+

Before you are able to start coding, you will have to compile the included
modules first. 
The compilation might take some time. Windows users might need to make a 
coffee as MinGW needs slightly more time to do its job compared to its
compagnons on other OS.


Option A: MaxIDE (preferred way)
--------------------------------

- start MaxIDE[.exe]
- "Program" -> "Build Modules"


Option B: via Terminal / Command prompt
---------------------------------------
Windows users start their command prompt with executing "cmd"
(if you have a start menu. "Start" -> run -> "cmd").

  Linux/Mac
  ---------
  $ cd /path/to/BlitzMaxNG/bin
  $ ./bmk makemods

  Windows
  -------
  cd path/to/BlitzMaxNG/bin
  bmk.exe makemods

Both options will show you the progress of the compilation.




+===========================================+
| NEXT STEPS                                |
+===========================================+

There are none ... you are done now ... feel free to start coding as usual.

If you are interested in adding things (eg. specific target instructions) feel free to add them here until Brucey finds a nice spot to add all that things in a git-like-manner.

Segfaults when using "param:MyType var"

BlitzMax uses "pass by reference" automatically if the type is no simple one (no int, float, ...). BUT: it also does not complain if stated manually (I would use this to make clear: this variable is getting modified within the given function). Means: the following code works (read: compiles!) with BM vanilla, but not with BM-NG.

Whether this is something "intended" or not it might be needed if nearly 100% compatibility is tried to get achieved.

Framework brl.Standardio
local data:TData = new TData
LoadValuesToData(data)

Using Booleans in Calculation (x<>null)*(x<>null)

The following lines should explain everything needed:

'DOES WORK

'DOES NOT WORK
Print (myString<>Null)*(myString<>Null)

As soon as the booleans are directly connected (does not matter if "*" or "+/-/:") it creates a

Invalid function call should fail

This should fail compilation because no parameter was provided :

SuperStrict

count

Function count:Int(a:Int)

Error should be "Missing function parameter 'a'"

Instead, the C compiler throws an error because the generated code is invalid.

"conflicting types for ‘bbObjectNew’" when reusing module code

In my framework I use a variation of the "extended reflection code" posted at the blitzmax forums some long time ago.

Basically it is a alternative to the "brl.reflection" code (it extends it some way). Because "brl.mod/reflection.mod" needed some rewrites for NG, I had to rewrite that portions in my code too.

At the end this means:

I copied "reflection.cpp" to my source dir
copied "reflection.bmx" too (without the module portion + added some extensions to add support for "const")

But while the old cold compiled fine in "vanilla", the new one spits out errors:

./bmk makeapp -r ../TVTower/TVTower.bmx

...
and so on

So somehow there are interferences.

Implement Debugging support

Add support for Debug mode code generation, including support for the debug scope stack, etc.

BCC-Segfault when using Short/Byte/Double as For-Loop variable

Each of the following loops makes BCC segfault during compilation.

        For local x:short = 0 to 5
        Next
        For local y:byte = 0 to 5
        Next
        For local z:double = 0 to 5
        Next

Program received signal SIGSEGV, Segmentation fault.
0x08085eb7 in _bb_TForStmt_OnSemant ()

Int, Float and Long work as expected.

OnSemant() fails when trying to create the TBinaryExpr:

        Local assop:TAssignStmt=TAssignStmt( incr )
        Local addop:TBinaryExpr=TBinaryExpr( assop.rhs )

assop is this:

lhs: TVarExpr(Local x:Short)
op: =
rhs: TCastExpr(Short,(TCastExpr(Int,TVarExpr(Local x:Short)) + TConstExpr("1")))

Switching the expressions a bit (created an "int"-local and then manually used that varID):

lhs: TVarExpr(Local j:Int)
op: =
rhs: (TCastExpr(Int,TVarExpr(Local x:Short)) + TConstExpr("1"))

this does not segfault, so maybe this gives the right hint to solve the problem.

Failed global initialisation in method

Initialising a global array in a Type method generates incorrect code.

Type Class

    Method test()
        Global arr:Int[] = New Int[8]
    End Method

End Type

Array should be initialised on the first pass, and thereafter used as is.

Compile Error: Arrays cannot be compared.

Following code leads to error message "Compile Error: Arrays cannot be compared."

SuperStrict
Framework Brl.StandardIO


Global arrOne:Int[] = [1,2]
Global array:Int[] = arrOne
Global arrays:Int[][] = [arrOne]

'both fail
If arrays[0] = arrOne Then Print "absolutely true"
If array = arrOne Then Print "absolutely true too"

Seems BCC seems to error out because it does not know how to check individual entries of an array - but the comparison is more "is this the same array/reference" instead of "contains the same entries".

So if possible, the evaluation should be "true" if the both arrays are the same (reference wise).

Parsing Issue

Hey there,

Came across an issue trying to compile some modules:

While trying to build the entire scope, bcc threw a fit on this file:

https://github.com/kfprimm/prime.mod/blob/master/maxml.mod/maxml.bmx

root@blitzmax-build-env:~/BlitzMax/mod# bmk makemods 
Compiling:assetpacker.bmx

Of course, I know for a fact that the standard bcc can compile this file with no issues.

Running this on a fresh install of Ubuntu 14.04 x64.

Thanks!

negative sign before "var"-passed function parameter generates error

Another module not compiling:

Compiling:math3d.bmx
/BlitzMaxNG/mod/prime.mod/math3d.mod/.bmx/math3d.bmx.debug.linux.x86.c: In function ‘prime_math3d_TMatrix_Project’:
/BlitzMaxNG/mod/prime.mod/math3d.mod/.bmx/math3d.bmx.debug.linux.x86.c:1569:12: error: invalid type argument of unary ‘*’ (have ‘BBFLOAT’)
  *bbt_y=(((*-(*bbt_y))*0.5f)+0.5f);
            ^

The error is replicateable using this sample code:

type testtype
    field f:float

    Function test(f:float var)
        'fails
        f = -f*0.5
        'would work
        'f = -1 * f*0.5
    End Function
endtype

[vanilla-compatibility] unexpected ":" in call "super.MethodName:int()"

When extending a type and overriding a method you can call the parental method using "super.".

This uncommon call is not compiling:

SuperStrict
Import Brl.StandardIO

Type A
 Method call:Int()
 End Method
End Type

Type B Extends A
 Method call:Int()
   'failing with NG but possible with vanilla
   Super.call:Int()
 End Method
End Type

Not ignoring out of scope decls.

The example below does not compile because the local method is found first. However, in a function, a method is not in scope, and should be ignored.

SuperStrict

Framework brl.standardio

Local base:TBase = TBase.Create()

Type TBase

    Function Create:TBase()
        Local this:TBase = New TBase
        Build(this) ' call the function !
        Return this
    End Function

    Method Build(base:TBase) ' should be ignored because not in scope
        Print "M"
    End Method

End Type

Function Build(base:TBase)
    Print "F"
End Function
