Return a CodeSegAttr from a containing class.
The Microsoft docs say when __declspec(code_seg) "is applied to a class, all member functions of the class and nested classes – this includes compiler-generated special member functions – are put in the specified segment." The actual behavior is a little more complicated. The Microsoft compiler won't check outer classes if there is an active value from #pragma code_seg. The CodeSeg is always applied from the direct parent but only from outer classes when the #pragma code_seg stack is empty. See: https://reviews.llvm.org/D22931, the Microsoft feedback page is no longer available since MS has removed the page.

hasSimilarParameters - Determine whether the C++ functions Declaration and Definition have "nearly" matching parameters.
This heuristic is used to improve diagnostics in the case where an out-of-line function definition doesn't match any declaration within the class or namespace. Also sets Params to the list of indices to the parameters that differ between the declaration and the definition. If hasSimilarParameters returns true and Params is empty, then all of the parameters match.

Given that we are within the definition of the given function, will that definition behave like C99's 'inline', where the definition is discarded except for optimization purposes?
Definition at line 6604 of file SemaDecl.cpp.
Determine whether a variable is extern "C" prior to attaching an initializer.
We can't just call isExternC() here, because that will also compute and cache whether the declaration is externally visible, which might change when we attach the initializer.
This can only be used if the declaration is known to not be a redeclaration of an internal linkage declaration.
For instance:
auto x = []{};
Attaching the initializer here makes this declaration not externally visible, because its type has internal linkage.
FIXME: This is a hack.

Determines whether the given declaration is an out-of-scope previous declaration.
This routine should be invoked when name lookup has found a previous declaration (PrevDecl) that is not in the scope where a new declaration by the same name is being introduced. If the new declaration occurs in a local scope, previous declarations with linkage may still be considered previous declarations (C99 6.2.2p4-5, C++ [basic.link]p6).
PrevDecl | the previous declaration found by name lookup |
DC | the context in which the new declaration is being declared. |
