Re:[sdcc-devel] Bug with extern

[Sandeep D. <san...@us...>]

Michael,
The .globl is NOT required because we are assembling with
-losgff option the -g means all undefined symbols are assumed
to be globl i.e. the linker will resolve it. I tried the two following files
and it worked.

/* file ext1.c */
extern int ii ;
void foo()
{
    ii++;
}

/* file ext.c */
int ii ;
extern void foo();
main()
{
    foo();
]

sdcc -c ext1.c
sdcc ext.c ext1.rel


foo & ii were resolved correctly...
