Provide a more powerful and at the same time more readable way of specifying
taint propagation rules for known functions within the checker.
Now it should be possible to specify an unlimited amount of source and
destination parameters for taint propagation.
No functional change intended just yet.

Re-enable format string warnings on printf.
The warnings are still incomplete. Apparently it is undefined to use a
vector specifier without a length modifier, which is not currently
warned on. Additionally, type warnings appear to not be working with
the hh modifier, and aren't warning on all of the special restrictions
from c99 printf.

This reverts r348083. This was based on a misreading of the spec
for printf specifiers.
Also revert r343653, as without a subsequent patch, a correctly
specified format for a vector will incorrectly warn.
Fixes bug 40491.

It is intended to disable _all_ warnings, even those upgraded to

That weakens inner invariants, but allows the class to be more generic,
allowing usage in situations where the call expression is not known (or
should not matter).

According to the report, better to keep the original strict compare
operation as the loop condition with unsigned loop counters to make the
loop countable. This allows further loop transformations.

This fixes most references to the paths:
llvm.org/svn/
llvm.org/git/
llvm.org/viewvc/
github.com/llvm-mirror/
github.com/llvm-project/
reviews.llvm.org/diffusion/
to instead point to https://github.com/llvm/llvm-project.
This is *not* a trivial substitution, because additionally, all the
checkout instructions had to be migrated to instruct users on how to
use the monorepo layout, setting LLVM_ENABLE_PROJECTS instead of
checking out various projects into various subdirectories.
I've attempted to not change any scripts here, only documentation. The
scripts will have to be addressed separately.
Additionally, I've deleted one document which appeared to be outdated
and unneeded:

r352221 caused regressions in CUDA/HIP since device function may use _Float16 whereas host does not support it.
In this case host compilation should not diagnose usage of _Float16 in device functions or variables.
For now just do not diagnose _Float16 for CUDA/HIP. In the future we should have more precise check.

Introduce an option to request global visibility settings be applied to
declarations without a definition or an explicit visibility, rather than
the existing behavior of giving these default visibility. When the
visibility of all or most extern definitions are known this allows for
the same optimisations -fvisibility permits without updating source code
to annotate all declarations.

Summary:
As discussed in https://reviews.llvm.org/D57112#inline-506781,
'flush' clause does not exist in the OpenMP spec, it can not be
specified, and `OMPFlushClause` class is just a helper class.
Therefore `OPENMP_CLAUSE()` in `clang/Basic/OpenMPKinds.def`
should not contain 'flush' "clause".
I have simply removed the `OPENMP_CLAUSE(flush, OMPFlushClause)`
from `clang/Basic/OpenMPKinds.def`, grepped for `OPENMP_CLAUSE`
and added `OPENMP_CLAUSE(flush, OMPFlushClause)` back to the **every**
place where `OPENMP_CLAUSE` is defined and `clang/Basic/OpenMPKinds.def`
is then included.
So as-is, this patch is a NFC. Possibly, some of these
`OPENMP_CLAUSE(flush, OMPFlushClause)` should be dropped,
i don't really know.

Introduce a new class GenericSelectionExpr::Association which bundle together
an association expression and its TypeSourceInfo.
An iterator GenericSelectionExpr::AssociationIterator is additionally added to
make it possible to iterate over ranges of Associations. This iterator is a
kind of proxy iterator which abstract over how exactly the expressions and the
TypeSourceInfos are stored.

Summary:
Trying to use structure binding with a structure that doesn't implement
std::tuple_size, should unpack the data members. When the struct is a
template though, clang might hit an assertion (if the type has not been
completed before), because CXXRecordDecl::DefinitionData is nullptr.
This commit fixes the problem by completing the type while trying to
decompose the structured binding.
The ICE happens in real world code, for example, when trying to iterate
a protobuf generated map with a range-based for loop and structure
bindings (because google::protobuf::MapPair is a template and doesn't
support std::tuple_size).
