A significant number of our tests in C accidentally use functions
without prototypes. This patch converts the function signatures to have
a prototype for the situations where the test is not specific to K&R C
declarations. e.g.,
void func();
becomes
void func(void);
This is the third batch of tests being updated (there are a significant
number of other tests left to be updated).
When there is unknown type in a struct in code compiled with
-Wcast-align, the compiler crashes due to
clang::ASTContext::getASTRecordLayout() failing an assert.
Added check that the RecordDecl is valid before calling
getASTRecordLayout().
FunctionDecls.
This commit silences an incorrect warning that is issued when a function
pointer is cast to another function pointer type. The warning gets
issued because alignments of the source and destination do not match in
Sema::CheckCastAlign, which happens because ASTContext::getTypeInfoImpl
and ASTContext::getDeclAlign return different values for functions (the
former returns 4 while the latter returns 1).
This should fix PR31558.

Teach Sema to check the aligned attribute attached to variable
declarations so that it doesn't issue spurious warnings.

from GCC's in that we warn on *any* increase in alignment requirements, not
just those that are enforced by hardware. Please let us know if this causes
major problems for you (which it shouldn't, since it's an optional warning).
