This library will be used by clang-query. I can imagine LLDB becoming another
client of this library, so I think LLVM is a sensible place for it to live.
It wraps libedit, and adds tab completion support.
The code is loosely based on the line editor bits in LLDB, with a few
improvements:
- Polymorphism for retrieving the list of tab completions, based on
the concept pattern from the new pass manager.
- Tab completion doesn't corrupt terminal output if the input covers
multiple lines. Unfortunately this can only be done in a truly horrible
way, as far as I can tell. But since the alternative is to implement our
own line editor (which I don't think LLVM should be in the business of
doing, at least for now) I think it may be acceptable.
- Includes a fallback for the case where the user doesn't have libedit
installed.
Note that this uses C stdio, mainly because libedit also uses C stdio.

LLVM_REQUIRES_EH implies LLVM_REQUIRES_RTTI. It is as same behavior as Makefile.rule's.
llvm/examples/ExceptionDemo is affected. (It was built with -fno-rtti.)
For MSVC, Remove flags like "/EHsc /GR" in HandleLLVMOptions, or CL.EXE complains with flags like "/GR /GR-".
llvm_update_compile_flags() updates source file property if the target contains *.c.
COMPILE_FLAGS in target properties affects both C++ and C!
LLVM_NO_RTTI is deprecated. It was introduced by me and was my mistake.

It's hard to control contextual CMAKE_CXX_FLAGS. We should get rid of twiddling it as possible.

In Clang standalone tree, they points external dir (llvm-config's --bindir and --libdir).

This is needed to support the addition of tests for clang loadable plugins.
In clang, plugins are built as modules (bundles on OS X) rather than dynamic
libraries (dylib) so the build system needs to inform lit of the actual
file extension in use, typically '.so' on Unix and '.dll' on Windows.
(LLVM itself should probably switch to this scheme to fix PR14903 once and for
all.)
No change in build output or functionality intended.

Summary:
This parameter is required to build C++11 projects (like lld or lldb) on OS X as the default STL does not provide c++ classes.

Plugins need to go in build/Debug/lib as well (rather than build/lib/Debug).
Also, fix the SHLIBDIR path for Xcode, which by default includes Xcode build
settings rather than a simple %(build_mode)s parameter.

We have been seeing nasty directory layout with CMake multiconfig, such as,
bin/Release/clang.exe
lib/clang/3.x/...
lib/Release/clang/3.x/.. (duplicated)
Move the layout similar to autoconf's;
Release/bin/clang.exe
Release/lib/clang/3.x/...
Checked on Visual Studio 10. Could you guys please confirm my change on XCode(and other multiconfig builders)?
Note: Don't set variables CMAKE_*_OUTPUT_DIRECTORY any more, or a certain builder, for eaxample, msbuild.exe, would be confused.

The windows ninja build is now green, but msvs is still unhappy. Maybe that's
because the .def file was passed when building LTO_static, so only pass
symbol lists for shared libraries.

The command that cmd.exe is complaining about is:
cmd.exe /c cd /D C:\bb-win7\cmake-clang-i686-mingw32\build\tools\lto && cmake -E echo EXPORTS > symbol.def && type C:/bb-win7/cmake-clang-i686-mingw32/llvm-project/llvm/tools/lto/lto.exports >> symbol.def
Maybe quoting the filename helps.

The cmake build didn't support EXPORTED_SYMBOL_FILE. Instead, it had a
Windows-only implementation in tools/lto/CMakeLists.txt, a linux-only
implementation in tools/gold/CMakeLists.txt, and a darwin-only implementation
in tools/clang/tools/libclang/CMakeLists.txt.
This attempts to consolidate these one-offs into a single place. Clients can now
just set LLVM_EXPORTED_SYMBOL_FILE and things (hopefully) Just Work, like in
the make build.

This changes Clang standalone builds so that clang-tblgen lives in
clang/build/bin instead of llvm/build/bin, and so that with the Xcode
generator it's in clang/build/bin/Debug instead of llvm/build/bin/Debug/Debug/.
Yes, really.
llvm-svn: 197590
I think, in principle, intrinsics_gen may be added explicitly.
That said, it can be added incidentally, since each target already has dependencies to llvm-tblgen.
Almost all source files depend on both CommonTaleGen and intrinsics_gen.
Explicit add_dependencies() have been pruned under lib/Target.

add_public_tablegen_target adds *CommonTableGen to LLVM_COMMON_DEPENDS.
LLVM_COMMON_DEPENDS affects add_llvm_library (and other add_target stuff) within its scope.

In some case, it may be required to build LLVM in C++11 mode, as some the subprojects (like lldb) requires it.
This mimics the autoconf behaviour.
However, given the discussions on the switch to C++11 of the codebase, this behaviour should evolve to default to C++11 with some checks of the compiler capabilities.

for release builds.
This is a follow-up to r194589. Aaron pointed out that building
libraries with /MT and using them in an application that uses a
different run-time library can be a bad idea.
Move the option to build with /MT behind a CMake option so it can be
turned on selectively, such as when building the toolchain installer.

After r192904, Reid pointed out he thought we already set the stack
size for MSVC. Turns out we did, but it didn't seem to work.
This commit sets the stack size in a single place, using
CMAKE_EXE_LINKER_FLAGS because that seems to be the way that works
best.
llvm-svn: 192912
Compiling under Visual C++ 2012 with the default stack size of 1MB, the stack
overflows at a depth of 216 template instantiations, well before the 256
default limit. This patch modifies the default MSVC stack size to 2MB.
Patch by Yaron Keren!
llvm-svn: 192904
Summary:
The MSVCRT deliberately sends main() code-page specific characters.
This isn't too useful to LLVM as we end up converting the arguments to
UTF-16 and subsequently attempt to use the result as, for example, a
file name. Instead, we need to have the ability to access the Unicode
command line and transform it to UTF-8.
This has the distinct advantage over using the MSVC-specific wmain()
function as our entry point because:
- It doesn't work on cygwin.
- It only work on MinGW with caveats and only then on certain versions.
- We get to keep our entry point as main(). :)
N.B. This patch includes fixes to other parts of lib/Support/Windows
s.t. we would be able to take advantage of getting the Unicode paths.
E.G. clang spawning clang -cc1 would want to give it Unicode arguments.

I got a report of a hang in git's helper functions trying to figure out

the result is immediately piped to grep. This seems to avoid that.

It was removed in r189130, but it turns out this makes life hard for
folks packaging LLVM and Clang and building the latter based on the
LLVM package.
Note that this only adds back the LLVM tblgen, and it's obviously
not included when LLVM_INSTALL_TOOLCHAIN_ONLY is set.

LibXML2 config doesn't specify lzma as a dependency, which breaks
cross-compilation builds using new linkers (ld 2.21 or higher).
There is a bug on libxml2 to fix that, but since it's going to take
a while for things to go round and back, so we should have a harmless
addition of the library until then.
llvm-svn: 190409
Xcode always puts executable targets in the directory
bin/<Config>. When building separate LLVM and Clang projects for
Xcode, this prevents the CMake-configured project for Clang from
finding llvm-tblgen. Add a symlink so that tblgen executables are
always available in bin/ (regardless of the configuration LLVM is
built with).

Allow CMake to pick up external projects in llvm/tools without the need to modify the "llvm/tools/CMakeLists.txt" file.
This makes it easier to work with projects that live in other repositories, without needing to specify each one in "llvm/tools/CMakeLists.txt".
