Hi All,
When I compile the following code (using the -S switch) under windows,
GCC outputs an assembly file containing the symbol "__main" (two
underscores) Code:
int main()
{
return 0;
}
The reason I know that on some systems, gcc inserts a call to __main()
at the start of the code that it generates for main(). __main() is
called to
Execute initialization code, in particular constructors for C++ objects
with global or namespace scope.
Problem:
When I generate relocatable file (*.o) of (*.s) file then the
disassembly of 'jal __main" does not display properly in GDB
disassmebler. It displays as "jal 0x0<main>" because __main linked only
during linking process.
Can I get rid of __main in relocatable file or assembly file?
Thanks in advance
Regards,
