James Molloy's Tutorial Known Bugs: Difference between revisions

The tutorial states that the <tt>__cdecl</tt> calling convention is used. This is, however, a Windows term and your cross-compiler uses a similar calling convention but it is called the System V ABI for i386. It is advisable to understand this calling convention in depth, especially parts about how the parameters on the stack are clobbered and how structure parameters are passed. This will be very useful later and will help you avoid a later subtle bug. The function call example in 2.3 neglects to add 12 to esp following the call instruction and the three parameters are never thus popped.
