A function declared "inline" with an explicit "extern" storage class has the same semantics as if "inline" was omitted. (It is not an inline definition as defined in the C standards.) The "inline" specifier suggests that the function should be inlined, but it is legal to just ignore it, as we already do for "static inline" functions.
Also add a test for the inline function specifier.
This does not really do anything, because ORCA/C does not support multithreading, but the C11 and later standards indicate it should be allowed anyway.
Note that this implementation allows anonymous structures and unions to participate in initialization. That is, you can have a braced initializer list corresponding to an anonymous structure or union. Also, anonymous structures within unions follow the initialization rules for structures (and vice versa).
I think the better interpretation of the standard text is that anonymous structures and unions cannot participate in initialization as such, and instead their members are treated as members of the containing structure or union for purposes of initialization. However, all other compilers I am aware of allow anonymous structures and unions to participate in initialization, so I have implemented it that way too.
This was non-standard in various ways, mainly in regard to pointer types. It has been rewritten to closely follow the specification in the C standards.
Several helper functions dealing with types have been introduced. They are currently only used for ? :, but they might also be useful for other purposes.
New tests are also introduced to check the behavior for the ? : operator.
This fixes#35 (including the initializer-specific case).
These test various properties of the functions, including normal computations and edge case behavior. The edge case tests are largely based on Annex F, and not all of the behavior tested is required by the main specifications in the C standard. ORCA/C does not claim to fully comply with Annex F, but it provides useful guidelines that we try to follow in most respects.
These are currently only run by the new DOIT3 test-running script.
Note that these tests are designed to be applicable to most implementations of C95/C99/C11, not just ORCA/C. They do make certain assumptions not guaranteed by the standards (e.g. power of 2 types and some properties of IEEE-like FP), but in general those assumptions should be true for most 'normal' systems.
