[Bug middle-end/41149] New: -fdump-tree-original and procedure pointer components

[janus at gcc dot gnu dot org]

There seems to be a bug in the tree dump related to procedure pointer
components ('PPC', a Fortran 2003 feature which would probably be described as
"function pointers as structure components" in C). In particular: When calling
such a PPC, the dump only shows the component name, while the name of the
object which contains the component is omitted. This is not language dependent
and is also observed for C code, as the following example shows:


#include <stdio.h>

typedef long funcPtr(char *);

long func(char * str)
{
  printf("%s\n", str);
  return 0;
}

int main(void)
{
  long l;
  struct
  {
    funcPtr *ppc;
  } t;
  t.ppc = func;
  l = t.ppc("Hello");
  return l;
}


The dump shows (with -fdump-tree-original):

  t.ppc = (long int (*<T617>) (char *)) func;
  l = ppc ((char *) "Hello");

In the second line I would expect to see 't.ppc' instead of just 'ppc'.

For a Fortran example see PR 41139.
