Eric Fiselier 407584c433 Fix linkage error on ProgramPoint's dump method.
Currently, ProgramPoint::dump calls the out-of-line function ProgramPoint::print. This causes
libraries which include ProgramPoint.h to become dependent on libclangAnalysis, which in turn
causes missing symbol link error when building with -DBUILD_SHARED_LIBS=ON -DLLVM_ENABLE_MODULES=ON.

The breakage was introduced in r343160.

This patch fixes the issues by moving ProgramPoint::dump's declaration out of line.

Craig Topper 6ad9220067 [X86] Add the movbe instruction intrinsics from icc.
These intrinsics exist in icc. They can be found on the Intel Intrinsics Guide website.

All the backend support is in place to pattern match a load+bswap or a bswap+store pattern to the MOVBE instructions. So we just need to get the frontend to emit the correct IR. The pointer arguments in icc are declared as void so I had to jump through a packed struct to forcing a specific alignment on the load/store. Same trick we use in the unaligned vector load/store intrinsics

Saleem Abdulrasool f3a981e801 AST: add missing ObjC extensions to MS style name decoration
Add support for encoding type arguments for lightweight generics in
Objective-C++ mode.  Additionally, add support for the `__kindof` modifier.
This should complete the coverage of the ObjC extensions that clang currently
supports under the MS style name decoration scheme.

This is implemented similar to the Objective-C lifetime qualifiers decoration:
a template specialization in the `__ObjC` namespace so that we can interoperate
with Microsoft's tools as well as ensure that we do not accidentally collide
with new features in the Microsoft implementation.

Since the `__kindof` appertains to the type and not the pointer, we apply the
template specialization to the underlying type instead of the pointer type.

Unfortunately, until D52581 is resolved, the generated name is not really
compatible with the MS tools as well as breaks interoperability with
Objective-C++ and C++.

This resolves PR37754!

Richard Smith 9b2c5e7c44 [cxx2a] P0641R2: (Some) type mismatches on defaulted functions only
render the function deleted instead of rendering the program ill-formed.

This change also adds an enabled-by-default warning for the case where
an explicitly-defaulted special member function of a non-template class
is implicitly deleted by the type checking rules. (This fires either due
to this language change or due to pre-C++20 reasons for the member being
implicitly deleted). I've tested this on a large codebase and found only
bugs (where the program means something that's clearly different from
what the programmer intended), so this is enabled by default, but we
should revisit this if there are problems with this being enabled by
default.

Jonas Hahnfeld a981f67bcd [OpenMP] Improve search for libomptarget-nvptx
When looking for the bclib Clang considered the default library
path first while it preferred directories in LIBRARY_PATH when
constructing the invocation of nvlink. The latter actually makes
more sense because during development it allows using a non-default
runtime library. So change the search for the bclib to start
looking in directories given by LIBRARY_PATH.
Additionally add a new option --libomptarget-nvptx-path= which
will be searched first. This will be handy for testing purposes.

Previously we used a select and the zero_undef=true intrinsic. In -O2 this pattern will get optimized to zero_undef=false. But in -O0 this optimization won't happen. This results in a compare and cmov being wrapped around a tzcnt/lzcnt instruction.

By using the zero_undef=false intrinsic directly without the select, we can improve the -O0 codegen to just an lzcnt/tzcnt instruction.

If clang-tidy finds issues, it will fail the build since the warnings-as-errors is set.
If static analyzer finds anything, since --status-bugs is set, it will fail the build.
But if clang-tidy find anything, but static analyzer does not, the build succeeds :/

Fangrui Song 47db633239 [Frontend] Tidy up -print-decl-contexts conditions
The existing conditions are not consistent. Some have braces and define a temporary Decl while others simply call `<< *cast<XXXDecl>(I)` (mostly the NamedDecl overload of operator<<).

We mostly implemented this since Clang 6, but missed the template

We do not implement the '&cast-expression' special case. It appears to
be a mistake / oversight. I've mailed CWG to see if we can remove it.

Artem Dergachev e527df03c4 [analyzer] Add a testing facility for testing relationships between symbols.
Tests introduced in r329780 was disabled in r342317 because these tests
were accidentally testing dump infrastructure, when all they cared about was
how symbols relate to each other. So when dump infrastructure changed,
tests became annoying to maintain.

Add a new feature to ExprInspection: clang_analyzer_denote() and
clang_analyzer_explain(). The former adds a notation to a symbol, the latter
expresses another symbol in terms of previously denoted symbols.

It's currently a bit wonky - doesn't print parentheses and only supports
denoting atomic symbols. But it's even more readable that way.

Kristina Brooks 3ff0777064 [clang-check-codegen][cfstring] Accept either @ or % for progbits to make ppc64be bots happy.

Kristina Brooks 34e24d5b6a Reland "[Clang][CodeGen][ObjC]: Fix CoreFoundation on ELF with `-fconstant-cfstrings`"
Relanding rL342883 with more fragmented tests to test ELF-specific
section emission separately from broad-scope CFString tests. Now this
tests the following separately

1). CoreFoundation builds and linkage for ELF while building it.
2). CFString ELF section emission outside CF in assembly output.
3). Broad scope `cfstring3.c` tests which cover all object formats at
    bitcode level and assembly level (including ELF). 

This fixes non-bridged CoreFoundation builds on ELF targets
that use -fconstant-cfstrings. The original changes from differential 
for a similar patch to PE/COFF (https://reviews.llvm.org/D44491) did not
check for an edge case where the global could be a constant which surfaced
as an issue when building for ELF because of different linkage semantics.

This patch addresses several issues with crashes related to CF builds on ELF
as well as improves data layout by ensuring string literals that back
the actual CFConstStrings end up in .rodata in line with Mach-O.

Change itself tested with CoreFoundation on Linux x86_64 but should be valid
for BSD-like systems as well that use ELF as the native object format.

Artem Dergachev 579cf90367 [analyzer] NFC: Legalize state manager factory injection.
When a checker maintains a program state trait that isn't a simple list/set/map, but is a combination of multiple lists/sets/maps (eg., a multimap - which may be implemented as a map from something to set of something), ProgramStateManager only contains the factory for the trait itself. All auxiliary lists/sets/maps need a factory to be provided by the checker, which is annoying.

So far two checkers wanted a multimap, and both decided to trick the
ProgramStateManager into keeping the auxiliary factory within itself
by pretending that it's some sort of trait they're interested in,
but then never using this trait but only using the factory.

Make this trick legal. Define a convenient macro.

One thing that becomes apparent once all pieces are put together is that
these two checkers are in fact using the same factory, because the type that
identifies it, ImmutableMap<const MemRegion *, ImmutableSet<SymbolRef>>,
is the same. This situation is different from two checkers registering similar
primitive traits.
