Re: [RFC] Eliminate NESTED_ATTR_FUNC


#include<stdio.h>

void foo (int a, int b, void (*hook) (int aa, int bb, int cc))
{
  b += a;
  hook (a, b, a + b);
}

void qq (int a)
{
  auto void q1 (int aa, int bb, int cc);
  void q1 (int aa, int bb, int cc)
    {
      printf ("%d %d %d\n", a, aa + bb, cc);
    }

  foo (a, a + 1, q1);
}

int main()
{
  qq (10);
}

Compile with:
gcc -m32 -mregparm=3 -Os test.c

./a.out
10 31 -6674368

Ok, this was the only important part of the message to us GCC hackers. :-)

Can you please report a bug in bugzilla, saying which versions work and which fail? Also can you write in the report what was your analysis with respect to regparm?

Thanks!

Paolo
