Install the 'clang-cpp' symlink used to spawn the preprocessor. The code
handling this suffix is already included in Driver. FreeBSD is already
creating such a symlink in ports, and a similar one was requested
by Gentoo/FreeBSD team. The goal is to handle software that takes a C
preprocessor via a variable but does not handle passing options
correctly (i.e. 'clang -E' does not work).

LD64 does optimization on symbol layouts that gets disabled whenever an order file is passed (even if it is empty). This change prevents disabling that optimization, and still enables iterative generation and usage of order files.
If the order file is empty it does not setup the order file flags, instead it sets the empty order file as a configuration dependency. When the order file changes it will then trigger a re-configuration that adds the linker flag.
llvm-svn: 278306
This is re-landing r260742. I've reworked the conditionals so that it only hits when targeting Apple platforms with ld64.
Original Summary:
With this change generating clang order files using dtrace uses the following workflow:
cmake <whatever options you want>
ninja generate-order-file
ninja clang
This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.
CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.
llvm-svn: 265864
The CMake EXISTS operator needs to have the variable expanded. Not expanding this was causing the if statement to always be false, which made it impossible to pass linker order files in.
llvm-svn: 264757
This appears to be passing '-Wl,-order_file' to Linux link commands,
which then causes the linker to silently, behind the scenes, write the
output to 'rder_file' instead of somewhere else. Will work with Chris to
figure out the proper support for this, but so far there are numerous
people who can't get Clang to update when they build because of this.
llvm-svn: 261054
Summary:
This commit re-lands r259862. The underlying cause of the build breakage was an incorrectly written capabilities test. In tools/Driver/CMakeLists.txt I was attempting to check if a linker flag worked, the test was passing it to the compiler, not the linker. CMake doesn't have a linker test, so we have a hand-rolled one.

This reverts commit r259862, and attempts to fix builder CMakeCaches.
Will try this again some other time...

This change brings forward the LLVM convention that "executables" are just runnable binaries, and "tools" are executables that are part of the project's install.
Having this abstraction will allow us to simplify some of the tool CMakeLists files, and it will standardize some of the install behaviors.
llvm-svn: 258209
LLVM_SUBMIT_VERSION and LLVM_SUBMIT_SUBVERSION are commonly used variable names in the autoconf build system. They seem to have leeched into clang's CMake in a few places, and should just be replaced by the LLVM_VERSION_* variables where appropriate.

Generation of clang symlinks now uses add_clang_symlink macro which uses add_llvm_symlink. Also the list of symlinks to generate is configurable via CLANG_LINKS_TO_CREATE.
This re-lands r248015, with fixes for clang symlinks to always be generated as part of the clang and install-clang targets.

CMake-2.8.12 is hardcoded to create symlinked clang.exe if the target property VERSION is present and the host is not Win32.
Then clang.exe-*.* is generated and clang.exe is symlinked to it.
lrwxrwxrwx. 1 bb bb 13 Jul 5 18:04 clang.exe -> clang.exe-3.7
-rwxr-x---. 1 bb bb 244763 Jul 5 18:04 clang++.exe

It made me unhappy when built binaries were copied to the Windows target.
FIXME: Could we just remove the target property VERSION in add_llvm_executable() ?
llvm-svn: 241403
Fix the build when no targets are enabled. This dependency is incurred by two
unfortunate entries in LinkAllPasses.h included from cc1_main.cpp:
llvm::createJumpInstrTablesPass();
llvm::createCodeGenPreparePass();
llvm-svn: 212084
Update clang to use the InstrProfReader from LLVM to read
instrumentation based profile data. This also switches us from the
naive text format to the binary format, since that's what's
implemented in the reader.
llvm-svn: 206658
This updates CodeGenPGO to use the ProfileDataReader introduced to
llvm in r203703 and the new API for writing out the profile introduced
to compiler-rt in r203710.

An option with the same name already exists in the makefile build.
The name CLANG_IS_PRODUCTION is historical. We should probably change it, but
should change the configure build at the same time.
llvm-svn: 203325
The separate Xcode project generated for Clang is putting the clang
executables into the same location where the LLVM executables are
going. This is wrong, and breaks the Clang build because we try to
create clang++ and clang-cl symlinks in the wrong place and to the
wrong place.
As a stop-gap to get these builds working again, teach the symlink
generation to point into the LLVM executable directory instead.
llvm-svn: 198319
Also stop setting passing -dead_strip explicitly for libclang and instead
rely on this now happening by default. (And make it happen by default for
add_clang_library, which doesn't use the library cmake functions from llvm.)
llvm-svn: 198200
This is a nop right now, but committing this first avoids a temporary breakage
when the llvm files change to not default to exporting symbols.

This is similar to how we divide up the StaticAnalyzer libraries to separate
core functionality to what is clearly associated with Frontend actions.
