Disassemblies!

For this code:

#include <iostream>
typedef unsigned long asDWORD;
struct asPoint
{
	float x,y;
};
struct asRect
{
	asPoint tl, br;
};
asPoint TestPoint(void)
{
	asPoint p={1,2};
	return p;
}
asRect TestRect(void)
{
	asRect r={{3,4}, {5,6}};
	return r;
}
int main()
{
	asPoint t = TestPoint();
	asRect t2 = TestRect();
	std::cout << "X: " << t.x << ".\n";
	std::cout << "Y: " << t.y << ".\n";
	std::cout << "Rect X1: " << t2.br.x << ".\n";
	std::cout << "Rect Y1: " << t2.br.y << ".\n";
}

As you said - it appears that values are being returned in registers.

And I found this information in a doc called "Procedure Call Standard for the ARM® Architecture":
5.4
Result Return
The manner in which a result is returned from a function is determined by the type of that result.
For the base standard:
A Half-precision Floating Point Type is converted to single precision and returned in r0.
A Fundamental Data Type that is smaller than 4 bytes is zero- or sign-extended to a word and returned in r0.
A word-sized Fundamental Data Type (e.g., int, float) is returned in r0.
A double-word sized Fundamental Data Type (e.g., long long, double and 64-bit containerized vectors) is returned in r0 and r1.
A 128-bit containerized vector is returned in r0-r3.
A Composite Type not larger than 4 bytes is returned in r0. The format is as if the result had been stored in memory at a word-aligned address and then loaded into r0 with an LDR instruction. Any bits in r0 that lie outside the bounds of the result have unspecified values.
A Composite Type larger than 4 bytes, or whose size cannot be determined statically by both caller and callee, is stored in memory at an address passed as an extra argument when the function was called (§5.5, rule A.4).
The last paragraph has a reference to the following:
Stage A – Initialization
This stage is performed exactly once, before processing of the arguments commences.
A.1 The Next Core Register Number (NCRN) is set to r0.
A.2.cp Co-processor argument register initialization is performed.
A.3 The next stacked argument address (NSAA) is set to the current stack-pointer value (SP).
A.4 If the subroutine is a function that returns a result in memory, then the address for the result is placed in r0 and the NCRN is set to r1.
And in the chapter related to the VFP processor (in charge of floating point operations) it says:
6.1.2.2
Result return
Any result whose type would satisfy the conditions for a VFP CPRC is returned in the appropriate number of consecutive VFP registers starting with the lowest numbered register (s0, d0, q0).
All other types are returned as for the base standard.
Hope this helps.

Yes, both types are returned in registers. The Point type is returned in s0 and s1, and the Rect type is returned in s0, s1, s2, and s3.

This is not according to the Standard ARM ABI that you quoted, which is not surprising. I have yet to see any platform that follows the standard to the letter.

Anyway. This requires a bit of special handling in the AngelScript code. Both types have been registered with the following flags:

asOBJ_VALUE|asOBJ_POD|asOBJ_APP_CLASS|asOBJ_APP_CLASS_ALLFLOATS

The last flag, i.e. asOBJ_APP_CLASS_ALLFLOATS, is what needs to be used to identify this scenario.

I imagine something like this:

if( descr->returnType.IsObject() &&
    !descr->returnType.IsObjectHandle() &&
    !descr->returnType.IsReference() &&
    !(descr->returnType.GetObjectType()->flags & COMPLEX_RETURN_MASK) &&
    (descr->returnType.GetObjectType()->flags & asOBJ_APP_CLASS_ALLFLOATS) )
{
   CopyReturnedObjectFromSRegisters(retPointer, descr->returnType.GetSizeInMemoryDWords());
}

Where CopyReturnedObjectFromSRegisters() would be a function written in assembler to copy the s0, s1, s2, and s3 to the memory referred to by retPointer, based on the size.

With this complexity in how returned values are treated in the ABI you'll probably have to ignore sysFunc->hostReturnInMemory that is determined by PrepareSystemFunction(). Or, you need to change the PrepareSystemFunction() too to properly detect when a type is returned in memory or not.

Before making decisions though, you'll need to understand how other types are returned.

For example how would the following types be returned:

struct Int4 { int a; };                         // Part of testcdecl_class.cpp
struct Int8 { int a, b; };                     // Part of testcdecl_class.cpp
struct Int12 { int a, b, c; };                // Part of testcdecl_class.cpp
struct Float20 { float a, b, c, d, e; };  // not covered in any test. Register with same flags as Point and Rect

I imagine the types will be returned as following:

Int4 -> r0
Int8 -> r0 and r1
Int12 -> memory      (though could possibly be r0, r1, and r2)
Float20 -> memory  (though could possibly be s0, s1, s2, s3, and s4)

Based on the #defines that the compiler provides by default, it appears that the Raspberry Pi platform is treated just like Linux with ARM. I can't see anything that specifically identifies Raspberry Pi.

These are the defines of interest:

#define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4 1
#define __unix__ 1
#define __ARMEL__ 1
#define __linux 1
#define __linux__ 1
#define __gnu_linux__ 1
#define __GNUC__ 4
#define __GNUC_PATCHLEVEL__ 3
#define __GNUG__ 4
#define unix 1
#define __unix 1
#define linux 1
#define __arm__ 1
#define __GNUC_MINOR__ 6
#define __ARM_EABI__ 1

This means that as_config.h will go into the section for the GNUC compiler with Linux operating system and ARM cpu. The specifics for this target platform are defined on the lines 738 to 753, which gives the following:

// Platform
#define AS_LINUX
#define AS_ARM

// Method pointer structure
#define GNU_STYLE_VIRTUAL_METHOD
#define MULTI_BASE_OFFSET(x) (*((asDWORD*)(&x)+1))

// Parameter treatment
#define COMPLEX_MASK (asOBJ_APP_CLASS_DESTRUCTOR)
#define COMPLEX_OBJS_PASSED_BY_REF
#define AS_CALLEE_DESTROY_OBJ_BY_VAL


// Return value treatment
#define COMPLEX_RETURN_MASK (asOBJ_APP_CLASS_DESTRUCTOR)
#define CDECL_RETURN_SIMPLE_IN_MEMORY
#define CDECL_RETURN_SIMPLE_IN_MEMORY_MIN_SIZE 2
#define CALLEE_POPS_HIDDEN_RETURN_POINTER
#define THISCALL_RETURN_SIMPLE_IN_MEMORY
#define THISCALL_RETURN_SIMPLE_IN_MEMORY_MIN_SIZE 2
#define THISCALL_CALLEE_POPS_HIDDEN_RETURN_POINTER
#define STDCALL_RETURN_SIMPLE_IN_MEMORY
#define STDCALL_RETURN_SIMPLE_IN_MEMORY_MIN_SIZE 2

// Miscellaneous
#define STDCALL __attribute__((stdcall))
#define AS_POSIX_THREADS
#define AS_NO_ATOMIC
#define AS_SIZEOF_BOOL 1
#define ASM_AT_N_T
#define AS_ALIGN

With the current information that I have, I believe the configuration in as_config.h is correct for the RPi. Except that we probably need to increment something to specifically identify that structures containing only floats are handled differently than others.

What do you see in these disassemblies?

All except Int4 are returned in memory. Int4 is returned in R0.

This is good, because it means that the configuration in as_config.h is correct, i.e. it should be:

#define CDECL_RETURN_SIMPLE_IN_MEMORY
#define CDECL_RETURN_SIMPLE_IN_MEMORY_MIN_SIZE 2

You just need to add the exception when the object type is registered with asOBJ_CLASS_ALLFLOATS, where structs at most 32 bytes in size are returned in the registers.

Ok. So if, and only if, the type has been registered with asOBJ_CLASS_ALLFLOATS I have to do the "copy from registers to retPointer", and the rest of cases are supposedly being handled by the default behaviour, right?

Edit: Success!!! Now onto the next error....Posted Image Posted Image

Andreas:

Now I´m having trouble with the TestCDecl_ClassK test. It fails on line 114, with a "Failed to assign object returned from function. c1.a = ....". All tests before and after this one pass until the assertion at line 62 (function static void class1ByVal(ClassK1 c) ) which fails.

I can see that the class that fails is the one with just 1 member - does this have to do with the disassemblies we had before, when we found that classes with 1 member are returned in r0, and all of the others are returned in memory? Where do I look now?

This one is simpler. It has to do with what the compiler considers when determining if a class/struct is 'simple' or 'complex'. If all other tests pass before that, then it would seem the compiler looks for the existance of the destructor and or the copy constructor to determine that the class is 'complex'.

Change as_config.h to include the following defines on line 742:

#undef COMPLEX_MASK
#define COMPLEX_MASK (asOBJ_APP_CLASS_DESTRUCTOR | asOBJ_APP_CLASS_COPY_CONSTRUCTOR)
#undef COMPLEX_RETURN_MASK
#define COMPLEX_RETURN_MASK (asOBJ_APP_CLASS_DESTRUCTOR | asOBJ_APP_CLASS_COPY_CONSTRUCTOR)

That worked, thanks! Now TestCDecl_ClassK passed. The next error is appearing when calling the armFuncObjLast function, but since I still haven´t worked on it that´s to be expected.

I´ll let you know how it goes.

(and after almost 20 days.....)

All tests passed succesfully!!!

I only modified the armFunc, armFuncR0 and armFuncObjLast functions, but the others passed their respective tests too... what can that mean?

What´s the next step? I guess trying to pass the tests that were commented out.

I´ll be awating instructions!

It's quite possible that my tests don't cover all situations required to fully test the ABI. I'll take a look at those later to see if the tests really should cover the other ARM funcs too. But I wouldn't worry too much about that. We'll have to make adjustments later as the problems are discovered.

I suggest running the rest of the test suite to see if there is nothing seriously wrong. If you don't find any errors, I'd like to receive the code you've changed so far so I can merge it with the SDK.

I´ve got some errors with the other tests:

The Addon_debugger passed.
The scriptbuilder test reports an "unexpected token "[" at 38,2 and 39,2 and fails. The I get a segmentation fault.

I commented out the scriptbuilder test and scriptMath and serializer tests passed, but then the GC complaint that it couldn´t free an object of type "_builtin_function_" because it was being kept alive by the app.

Then the ScriptHandle and ScriptArray tests passed and I got a segmentation fault.

I tried commenting the first 4 tests (debugger, scriptBuilder, Math and serializer) and I got the GC complaints at the beginning. Then ScriptArray and ScriptHandle passes, the segmentation fault.

Any ideas of where to look for the problem? I´m guessing the asm routines?

EDIT: No, it´s not the asm routines. I commented out only the first test, then the scriptbuilder fails with the "unexpected token" message and then I get the seg fault, with no asm functione being called.

I had similar problems when testing on Linux before the release of 2.25.2. These were all fixed, so I suggest you merge your changes with the latest release and see if the problems remains.

Tried with AS 2.25.2, and got almost the same behaviour. There´s no more "unexpected token" error, but after a couple of tests I get the "CG couldn´t free object of type "_builtin_function_" and the a segmentation fault.

It could be a platform specific problem. Without debugging the code myself it's really hard to guess what is wrong.

Can you skip this test and see how many of the others that work successfully?

Ok, just tested disabling some of the tests:

- If I disable all the first 7 tests (the Addon tests) then the seg fault is gone until the TestRefArgument test is executed. It produces a seg fault.

- There is a number of tests that produce assertion failures. These are:

TestScriptClassMethod
TestScriptString
TestCompiler
TestRegisterType
TestVector3
TestStdString

I guess these assert failures mean I still have to tweak the code to make it work. But what about the seg faults caused by the addons?

It's possible the segfaults are due to the code for the native calling conventions are not properly cleaning up the stack after returning, or that the armFuncs don't keep the value of registers that are not supposed to be modified. It could also be something else entirely. It is almost certainly platform specific though as these problems don't happen on other platforms.

The only way to know for sure is to debug and find the cause.
