Use the right type when taking the address of a non-virtual member function pointer. Fixes PR6258.

llvm-svn: 95524

Fix the bug that was breaking self-host, and re-land the static ctor fixes.

Revert r95363 and r95375, which broke self-host.

llvm-svn: 95389

Fix array initialization test.

llvm-svn: 95375

If a global initializer has a non-trivial destructor it can't be emitted as a constant (even if it has a trivial constructor).

llvm-svn: 95363

Calculate offset correctly when taking the address of a virtual member function.

Revert "Numerous changes to selector handling:", this breaks a whole bunch of
working code, for no apparent reason.

Numerous changes to selector handling:

- Don't use GlobalAliases with non-0 GEPs (GNU runtime) - this was unsupported and LLVM will be generating errors if you do it soon. This also simplifies the

Numerous changes to selector handling:

- Don't use GlobalAliases with non-0 GEPs (GNU runtime) - this was unsupported and LLVM will be generating errors if you do it soon. This also simplifies the code generated by the GNU runtime a bit.

- Make GetSelector() return a constant (GNU runtime), not a load of a store of a constant.

- Recognise @selector() expressions as valid static initialisers (as GCC does).

- Add methods to GCObjCRuntime to emit selectors as constants (needed for using @selector() expressions as constants. These need implementing for the Mac runtimes - I couldn't figure out how to do this, they seem to require a load.

- Store an ObjCMethodDecl in an ObjCSelectorExpr so that we can get at the type information for the selector. This is needed for generating typed selectors from @selector() expressions (as GCC does). Ideally, this information should be stored in the Selector, but that would be an invasive change. We should eventually add checks for common uses of @selector() expressions. Possibly adding an attribute that can be applied to method args providing the types of a selector so, for example, you'd do something like this:

- (id)performSelector: __attribute__((selector_types(id, SEL, id)))(SEL)
withObject: (id)object;

Then, any @selector() expressions passed to the method will be check to ensure that it conforms to this signature. We do this at run time on the GNU runtime already, but it would be nice to do it at compile time on all runtimes.

- Made @selector() expressions emit type info if available and the runtime supports it.

Someone more familiar with the Mac runtime needs to implement the GetConstantSelector() function in CGObjCMac. This currently just assert()s.

unused variable warning.

Convert the type of the LValue offset variable in APValue to CharUnits, moving
the LValue-related methods of APValue out of line to avoid header file leaching.

Avoid assert-crash in a case where the expression passed to EmitConstantExpr
legitimately has side-effects (and needs to be generated as a non-constant).
