Fortran class allocation

[fxcoudert]

I've run about 15% of the gfortran testsuite so far, and I get relatively few failures. The ones I got are all related to handling and allocation of classes. One example is:

$ cat allocate_with_source_7.f08 
program test
  type P
    class(*), allocatable :: X(:)
  end type
  Type(P) Y
  integer, parameter :: arr(1) = (/ 5 /)

  allocate(Y%X, source=arr)
end
$ ./bin/gfortran allocate_with_source_7.f08 && ./a.out

Program received signal SIGBUS: Access to an undefined portion of a memory object.

Backtrace for this error:

Could not print backtrace: libbacktrace could not find executable to open
#0  0x102ca0747
#1  0x102c9f7bb
#2  0x1d2bf9c83
#3  0x102c87d4b
zsh: bus error  ./a.out

The code generated for the allocate statement is generating undefined access. I can't quite figure out how this happens, exactly. Also, the backtrace is useless — not sure why.

[iains]

a) there's no guarantee that the calling ABI is correct b) I have been successful in building a stage 1 compiler with debug and using LLDB to do simple debug c) libbacktrace might require some work .. dunno how much is generic. sorry that's not more helpful .. if you can find some specific place that the call to a library function has the wrong argument list or similar, then we can fix that (it's a question of going through each case and finding a work-around that is good for both normal and variadic fns).

[iains]

d) would we expect the allocation to end in a call to malloc? (that ought to work reliably, I'd think - it's not a variadic fn) e) If there's any code that has baked in assumptions about page size being 4096, that will need to be fixed (the page size here is 16384, AFAICT). it would be good to find out which part of the process is failing if debugging is possible.

[fxcoudert]

I will debug further. The current test results, with a non-bootstrap compiler, are:

Hum, the backtrace says the out-of-bounds access is in the copy code, that's weird:

* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=2, address=0x100003a68)
    frame #0: 0x0000000100003a84 a.out`__copy_INTEGER_4_.0 at a.f90:1

   2      type P
   3        class(*), allocatable :: X(:)
   4      end type
   5      Type(P) Y
   6      integer, parameter :: arr(1) = (/ 5 /)

That method seems safe:

__copy_INTEGER_4_ (integer(kind=4) & restrict src, integer(kind=4) & restrict dst)
{
  *dst = *src;
}

and from the dump trees, it should be called with the right parameters. I'm puzzled by this one…

[fxcoudert]

I can still see this, and many other testcases failing on the same pattern:

$ cat associate_13.f90                                                  
  type :: mytype
    integer :: i
  end type
  type :: myderivedtype
     class(mytype), allocatable :: x
  end type
  type(mytype) :: z
  type(myderivedtype) :: toto

  z = mytype(99)
  allocate (toto%x)
  toto%x = z
end
$ ./bin/gfortran associate_13.f90 && ./a.out

Program received signal SIGBUS: Access to an undefined portion of a memory object.

Backtrace for this error:

zsh: bus error  ./a.out

This is allocating memory just fine, and I think the issue is the passing of arguments into the copy function __copy_MAIN___Mytype:

__copy_MAIN___Mytype (struct mytype & restrict src, struct mytype & restrict dst)
{
  *dst = *src;
}

MAIN__ ()
{

I am not sure how to break at that function, and examine the content of the two function parameters.

[fxcoudert]

OK I think there is something wrong with passing some structs. Here is another issue, also related to a function call passing structs:

$ cat pr62125.f90 
module m
 implicit none
 type, abstract :: t1
  logical :: l
 end type t1
 type, extends(t1), abstract :: t2
  integer :: i
 end type t2
 type, extends(t2) :: t3
  real :: x
 end type t3
contains
 subroutine s(u)
  class(t1), intent(in) :: u
   select type(u); class is(t2)
     select type(u); class is(t3)
     end select
   end select
 end subroutine s
end module m

program p
 use m
 implicit none
 type(t3) :: var = t3( l=.true. , i=2 , x=3.5 )
 call s(var)
end program p
$ ./bin/gfortran pr62125.f90 -O2 && ./a.out

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

Could not print backtrace: libbacktrace could not find executable to open
#0  0x104c7b577
#1  0x104c7a5eb
#2  0x1d2bf9c83
#3  0x104b67ea3
zsh: segmentation fault  ./a.out

This time the error is in libgfortran's _gfortran_is_extension_of: the second argument is pointing, which is the derived type's vtab, gets passed wrong when optimising at -O2. The pointer points to a wrong location.

This is rather heavily-tested code, both in front-end and runtime library, so I don't think it's an issue with the front-end emitting wrong types. I don't know how to debug further, though :(

[iains]

I don't suppose there's a C equivalent? it would be a little easier to debug.

@iains no sorry, I tried to create a C code that would be similar, but it does not trigger the issue. The generated code is minimal, though (a dozen lines or so in the tree dump). I am not sure how to better help find out the root cause, sorry.

[iains]

AFAIU, there is no "fortran-specfic" ABI - that is, GCC maps Fortran language constructs onto the regular "C" platform calling conventions.

I'll have to try adding some debug - lldb doesn't understand Fortran too well at the moment. As things stand it seems that the second argument to the interger_4 copy routine is bogus (points somewhere in the text section).

What's odd is that the output of compat.exp / struct-layout-1.exp for C suggest that we are quite internally consistent in calling functions with the arguments in the place that the callee expects them - we are not so good between GCC<=>clang, but that's not the circumstance we have here - we're calling a function we compiled.

Will have a poke at debugging this sometime soonish.

        bl      _malloc
LVL5:
        cbz     x0, L5

see if there's a NULL return

LBB9:
        str     x0, [sp]

save the pointer to memory

        adrp    x0, ___vtab_INTEGER_4_.2@PAGE
        add     x0, x0, ___vtab_INTEGER_4_.2@PAGEOFF;momd
        ldr     x1, [x0, 32]

get the address of the __copy_INTEGER4.0 function

        adrp    x0, _arr.3@PAGE
        add     x0, x0, _arr.3@PAGEOFF;momd

get a pointer to arr3

        blr     x1

call __copy_INTEGER_4_.0

BUT:

___copy_INTEGER_4_.0:

        ldr     w0, [x0]
        str     w0, [x1]
        ret

SO .. it seems that somehow we're using the destination address reg ___copy_INTEGER_4_.0 expects as the scratch to load the indirect call.

might be a code-gen problem rather than a CC one.

[iains]

or somehow we think that ___copy_INTEGER_4 has a function signature like:

___copy_INTEGER_4 (source,...)

which seems a bit unlikely ... ... perhaps I'm just missing tweaks to indirect calling sequences :(

expand_call doesn't seem to get a function decl - and the function type seems to be like a K&R unprototyped func - i.e void (*fun)()

So, I guess that explains why we push the second part onto the stack... ... now the question is why we think this.

[iains]

BTW, this is on a cross-compiler, so the compiler is X86_64 code ... therefore, I'd hope we don't expect wrong code there.

How are the entries in a Fortran vtable typed?

I've stepped through the code - and it's doing what I would expect given a function signature void (*f) ()

the code correctly determines there are two call arguments, and it determines that there's one named arg - the () produces an arglist with as the only entry.

[iains]

so .. it seems that x86_64 gets the same information, but it passes the parms the same way as it would if they were named (I suspect this is the common case - and is true for 'regular' aarch64, too). I can check for powerpc darwin, but IIRC that duplicates the values in register and on the stack - so that it looks the same too.

This is somewhat problematical - since the darwinpcs ABI for variadic functions does not pass in registers, after the last named one.

I guess what we need to explore, is why the function type/decl is not available (presumably the type of the vtable entries must be known, something "knew" which entry to use).

So, despite that this is "well tested" on other platforms - it seems that we have not encountered this set of circumstances before.

I've emailed the Fortran maintainers at https://gcc.gnu.org/pipermail/fortran/2020-September/054978.html Indeed the front-end knows the prototype for that function, so it should emit it.

[iains]

thanks, I saw that (lurker on that list).

I wonder if we can use the VOID list node to detect that we have a "k&r" style function definition and switch the call lowering to use the "force everything to be treated as named" (there is such a mode).

Of course, that's not really a substitute for proper information (it would get things wrong if you really did have a variadic function as one of the entries, I think).
