Try compiling code below with
h8300-coff-gcc -fomit-frame-pointer -mh -mn bug.c
==================================================
void foo(int a, int b, int c, int d)
{
}
void bar ( char a, char b )
{
}
void main(void)
{
char a ;
foo(1,2,3,4);
a = 10;
bar(a, 1);
printf("a=%d\n", a);
}
==================================================
h8300-hms-run a.out prints
a=244
If you see the generated assembly, variable a is accessed using -ve offset from
SP. It should be +ve offset.
mov.b r2l,@(-1,er7) ;# a
The problem doesn't appear if line calling function foo() is commented.
I think this is related to INITIAL_ELIMINATION_OFFSET.

Reduced to:

Probably the following better describes the problem.
You get a positive (correct) offset for "a = 10;"
and a negative one for "return a;".
So I doubt the problem is related to INITIAL_ELIMINATION_OFFSET.
void foo (int, int, int, int);
short
bar (void)
{
short a = 10;
foo (0, 0, 0, 0);
return a;
}
