Project Name
GCC alwayszero function attribute
Project Description
This project involves extending gcc to support an alwayszero function attribute (see Bug #517370 for an overview). Essentially, a call to an alwayszero function foo in such contexts as if (foo() != 0) or while (foo() != 0) should completely ignore the test and automatically branch to the next statement upon return of the function, ignoring the check.
