Changed llvm/CMakeLists.txt and added relative path to llvm doxygen

Authored by yamaguchi on Apr 21 2017, 1:43 AM.



Fist part is to change CMakeLists.txt and by following reasons:
In llvm/docs/CmakeLists.txt, it was

  • set(abs_top_srcdir ${LLVM_MAIN_SRC_DIR})
  • set(abs_top_builddir ${LLVM_BINARY_DIR})

However, ${LLVM_MAIN_SRC_DIR} is not an environmental variable but just a normal local PATH, which is substituted by llvm/CmakeLists.txt as follows:

298 set(LLVM_MAIN_INCLUDE_DIR ${LLVM_MAIN_SRC_DIR}/include ) # --includedir

In clang/docs/CmakeLists.txt, ${CMAKE_CURRENT_FOO_DIR} is used, so it is good to follow its way.

Also, I added README.txt how to generate llvm doxygen.

Second part is to change #include <Foo.h> to #include "Foo/Foo.h" as we did in clang [1].
It will change #include <jitprofiling.h> to #include "ExecutionEngine/IntelJITEvents/jitprofiling.h"

I think most of the changes are just necessary because we replaced LLVM_MAIN_SRC_DIR with CMAKE_SOURCE_DIR (all the added ../ and removed docs). On the other hand this is now in sync with the way the the clang doxygen.cfg is structured and it fixes the include paths, so I think this looks reasonable.


cmake cmake => cmake and I guess -DDOXYGEN_FOUND =>-DLLVM_ENABLE_DOXYGEN=On.

And we really need documentation for building this. The only search results I find for this are instructions for the pre-CMake era.

Anyway, the intended way is (at least from what I can see) to just run:

cmake -DLLVM_ENABLE_DOXYGEN=On <src-dir>
make doxygen-llvm # for LLVM docs
make doxygen-clang # for clang docs

instead of invoking doxygen by yourself. Could you change this?
