Issue with allocating stack space to local variables (frame pointer)

["Sivaprasad.pv" <sivaprasad.pv@xxxxxxxxxxxxxxxxxx>]

Hi all,

We are trying to port gnu gcc for our custom processor. But it is giving 
problem for allocating stack to local (auto) variables.
for example:
    I declared  local variable in  following order.
                    int a, b, c;
                    char d;
                    short e, f, g;
                     char  h;
while allocating stack to these local variable it is leaving space which 
is equal to the size of that data type.
In above case before allocation of stack to
                   a, b, c it is leaving 4 bytes space in stack
                    d it is leaving 1byte of space in stack
                   e, f, g it is leaving 2 bytes of space in stack
                   h it is leaving 1 byte of space in stack (or 
overlapping with g)
Note:
According to our architecture integer is 32 bit size. all parameters, 
arguments, stack boundary  are 32 bit aligned.

I have tried to adjust  by defining "STARTING_FRAME_OFFSET" macro.But I 
am unable to get required results.
Could you please help me in this regard.

Thanks,
