r201059 appears to cause a crash in a bootstrapped build of clang. Craig
isn't available to look at it right now, so I'm reverting it while he
investigates.

I am sure it'd not be required any more.
In trunk, all of tablegen's users depend on ${TABLEGEN_OUTPUT} as not file dependency but inter-target dependency.

CMake's target_link_libraries() will manage dependencies with Brad's LLVMConfig improvements.
Configuration time may be reduced by a few seconds.

Some of the more complex directive and macro handling for GAS compatibility
requires lookahead. Add a single token lookahead in the MCAsmLexer.

Teach the Makefile build system to generate and install CMake modules
LLVMConfig.cmake and LLVMConfigVersion.cmake so that applications that
build with CMake can use 'find_package(LLVM)' even when LLVM is not
built with CMake. These modules tell such applications about available
LLVM libraries and their dependencies.
Run llvm-config to generate the list of libraries and use the results of
llvm-build to generate the library dependencies. Use sed to perform
substitutions in the LLVMConfig.cmake.in and LLVMConfigVersion.cmake.in
sources that our CMake build system uses.
Teach the Makefile build system to generate the LLVMExports.cmake file
with content similar to that produced by the CMake install(EXPORT)
command. Extend llvm-build with an option to generate the library
dependencies fragment for this file.

llvm-svn: 201053
Teach autoconf/configure.ac to AC_SUBST several additional values in
Makefile.config to make them available to Makefile code. These will
be useful to generate CMake package modules from the Makefile build.
Contributed by Brad King.
llvm-svn: 201052
Teach each package configuration file to load the LLVMExports file for
its corresponding tree. This will allow application CMake code to use
logical library and executable target names from LLVM as if they were in
our own build process (e.g. LLVMSupport). CMake will have enough
information to propagate LLVM library link dependencies automatically
while configuring applications.
Contributed by Brad King.
llvm-svn: 201051
Record every logical target that we install with install(TARGETS) in a
global LLVM_EXPORTS property. Then use the export(TARGETS) command to
provide a "LLVMExports.cmake" file that exports logical targets for
import into applications directly from our build tree.
The "LLVMExports.cmake" file is not meant for direct inclusion by
application code but should be included by "LLVMConfig.cmake" in a
future change.
Contributed by Brad King.
llvm-svn: 201050
Use the install(TARGETS) command EXPORT option for every library and
executable that we install with LLVM. Then use the install(EXPORT)
command to provide a "LLVMExports.cmake" file that exports logical
targets for import into applications from our install tree.
The "LLVMExports.cmake" file is not meant for direct inclusion by
application code but should be included by "LLVMConfig.cmake" in a
future change.
Contributed by Brad King.
llvm-svn: 201049
Create separate package configuration files "LLVMConfig.cmake" for the
LLVM build and install trees so that each can have information specific
to its tree. Configure each with the corresponding include, lib, and
cmake directories. Include the "LLVM-Config" API modules directly from
the configured cmake modules directory.
In the install tree, compute the installation prefix relative to the
file location. In the build tree, provide information specific to the
build tree for use by tools like Clang that can build externally against
the LLVM build tree. Prefix such values in "LLVM_BUILD_" and comment
them as such.
Contributed by Brad King.
llvm-svn: 201048
Do not modify this value on the application's behalf and just ensure API
modules are always available next to the LLVMConfig module. This is
already the case in the install tree so use file(COPY) to make it so in
the build tree. Include the LLVM-Config API module from next to the
LLVMConfig location.
Contributed by Brad King.

These methods normally call each other and it is really annoying if the
arguments are in different order. The more common rule was that the arguments
specific to call are first (GV, Encoding, Suffix) and the auxiliary objects
(Mang, TM) come after. This patch changes the exceptions.
llvm-svn: 201044
Rather than simply saying "X is not a class or namespace", clarify what
X is by providing the aka type in the case where X is a type, or
pointing to the named declaration if there's an unambiguous one to refer
to. In the ambiguous case, the ambiguities are already enumerated
(though could be clarified by describing what kind of entities they are)
Included a few FIXMEs in tests where some further improvements could be
made.

TargetInfo::getSuitableAlign() was introduced in r146762 and is defined
as alignof(std::max_align_t).
Introduce __ALIGNOF_MAX_ALIGN_T__ which exposes getSuitableAlign() so
that libc++ may take advantage of it.
llvm-svn: 201037
Fun fact: looking at the TableGen code (around TGParser.cpp:1166), the
only difference in handling is that adjacent regular string literals are
concatenated in the parser.
llvm-svn: 201035
They're called code fragments, but they are really multiline string
literals. Just spotted this usage in a patch by Aaron using "code
fragments" for holding documentation text. I remember someone bemoaning
the lack of multiline string literals in TableGen, so I'm explicitly
documenting that code fragments are multiline string literals.
Let it be known that any use case needing multiline string literals in
TableGen (such as descriptions of options, or whatnot) can use use
code fragments (instead of C-style string concatenation or exceedingly
long lines). E.g.
class Bar<int n>;
class Baz<int n>;
class Doc<string desc> {
string Desc = desc;
}
def Foo : Bar<1>, Baz<3>, Doc<[{
This Foo is a Bar, and also a Baz. It can take 3 values:
* Qux
* Quux
* Quuux
}]>;

template parameters, don't look for parameters of outer templates. If a problem
is found in a default template argument, point the diagnostic at the partial
specialization (with a note pointing at the default argument) instead of
pointing it at the default argument and leaving it unclear which partial
specialization os problematic.
llvm-svn: 201031
In some cases it is possible to have a personality 0 unwinding opcodes in the
extab (such as when .handlerdata is used in the assembly). Simply decode the 3
opcodes for that case.
llvm-svn: 201030
This makes the tests more readable by using the -arm-attributes decoding support
in llvm-readobj since that is now available. Change the invocation commands to
be similar to other test and use a more precise triple (the tests only require
ARM EABI support).
llvm-svn: 201029
Before conditional store vectorization/unrolling we had only one
vectorized/unrolled basic block. After adding support for conditional store
vectorization this will not only be one block but multiple basic blocks. The
last block would have the back-edge. I updated the code to use a vector of basic
blocks instead of a single basic block and fixed the users to use the last entry
in this vector. But, I forgot to add the basic blocks to this vector!
Fixes PR18724.

unique them and permits the implementation of dynamic_cast (and
anything else which knows it's working with a complete class
type) to compare their addresses directly.

Summary:
This avoids false positives from -Wmicrosoft when name lookup would
normally succeed in standard C++. This triggered on a common CRTP
pattern in clang, where a derived class would have a private using decl
to pull in members of a dependent base:
class Verifier : InstVisitor<Verifier> {
private:
using InstVisitor<Verifier>::visit;
...
void anything() {
visit(); // warned here
}
};
Real access checks pass here because we're in the context of the
Verifier, but the -Wmicrosoft extension was just looking for the private
access specifier.
