commit 42ac2818689e0e2f1bdc3d5c6610f4f413229324 Author: Edward O'Callaghan eocallaghan@alterapraxis.com Date: Mon May 26 17:38:23 2014 +1000
mainboard: -ffreestanding so 'main' is not necessarily entry
From the C specification in 5.1.2.1 Freestanding environment;
"In a freestanding environment (in which C program execution may take place without any benefit of an operating system), the name and type of the function called at program startup are implementation-defined."
Clang complains about these being missing as Clang is somewhat more strict about the spec than GNU/GCC is. An advantage here is that a different entry-point type-signature shall now be warned about at compile time.
