Bug ID: 60822
   Summary: Index register overwritten on m68k/coldfire
   Product: gcc
   Version: 4.8.2
Status: UNCONFIRMED
  Severity: major
  Priority: P3
 Component: target
  Assignee: unassigned at gcc dot gnu.org
  Reporter: pint at tlink dot de

I have a newlib based gcc-4.8.2 crosscompiler on a mingw host with this
configuration:

../gcc/configure --target=m68k-elf --prefix=/opt/gcc-4.8.2-m68k
--enable-threads --with-newlib --enable-static --with-gnu-as --with-gnu-ld
--enable-languages=c++
--with-headers=/src/gcc-4.8.2/build-gcc/../newlib/newlib/libc/include
--with-arch=cf

invoked with:

m68k-elf-gcc -mcpu=54455 -g0  -O2 -Wall -Wextra   -S test.cpp -otest.s

This test program:


struct X {
char fill0[80];
int a;
char fill1[90];
int b;

int Avg(int s) const {return (s * (long long)(a + b)) >> 17;}
};

int f=1;
int o;
extern X x;

int main()
{
o = x.Avg(f);
return 0;
}


Produces this output:

lea x,%a0
move.l #174,%d0
move.l #80,%d1
move.l %d3,-(%sp)
.cfi_offset 3, -12
moveq #15,%d3
move.l (%a0,%d0.l),%d1
add.l (%a0,%d1.l),%d1

Where the value #80 is overwritten before used in the last statement.

[Bug debug/38367] [4.1/4.2/4.3/4.4 regression] Wrong debug information for big endian function parameters

Sorry, I can't try it. The patch cannot be applied to 4.3.2. There is no
set_mem_size there in assign_parm_find_stack_rtl.
