Large Refactor of CMake build system This commit improves numerous functionalities of the OpenMP CMake build system to be more conducive with LLVM's build system and build philosophies. The CMake build system, as it was before this commit, was not up to LLVM's standards and did not implement the configuration stage like most CMake based build systems offer (check for compiler flags, libraries, etc.) In order to improve it dramatically in a short period of time, a large refactoring had to be done. The main changes done with this commit are as follows: * Compiler flag checks - The flags are no longer grabbed from compiler specific directories. They are checked for availability in config-ix.cmake and added accordingly inside LibompHandleFlags.cmake. * Feature checks were added in config-ix.cmake. For example, the standard CMake module FindThreads is probed for the threading model to use inside the OpenMP library. * OS detection - There is no longer a LIBOMP_OS variable, OS-specifc build logic is wrapped around the WIN32 and APPLE macros with !(WIN32 OR APPLE) meaning a Unix flavor of some sort. * Got rid of vestigial functions/macros/variables * Added new libomp_append() function which is used everywhere to conditionally or undconditionally append to a list * All targets have the libomp prefix so as not to interfere with any other project * LibompCheckLinkerFlag.cmake module was added which checks for linker flags specifically for building shared libraries. * LibompCheckFortranFlag.cmake module was added which checks for fortran flag availability. * Removed most of the cruft from the translation between the perl+Makefile based build system and this one. The remaining components that they share are perl scripts which I'm in the process of removing. There is still more left to do. The perl scripts still need to be removed, and a config.h.in file (or similarly named) needs to be added with #cmakedefine lines in it. But this is a much better first step than the previous system.

Re-indent the CMake refactor to two-space indention I apologize for this nasty commit, but I somehow overlooked Chandler's comment to re-indent these files to two space indention.

Adding Hwloc library option for affinity mechanism These changes allow libhwloc to be used as the topology discovery/affinity mechanism for libomp. It is supported on Unices. The code additions: * Canonicalize KMP_CPU_* interface macros so bitmask operations are implementation independent and work with both hwloc bitmaps and libomp bitmaps. So there are new KMP_CPU_ALLOC_* and KMP_CPU_ITERATE() macros and the like. These are all in kmp.h and appropriately placed. * Hwloc topology discovery code in kmp_affinity.cpp. This uses the hwloc interface to create a libomp address2os object which the rest of libomp knows how to handle already. * To build, use -DLIBOMP_USE_HWLOC=on and -DLIBOMP_HWLOC_INSTALL_DIR=/path/to/install/dir [default /usr/local]. If CMake can't find the library or hwloc.h, then it will tell you and exit. Differential Revision: http://reviews.llvm.org/D13991 llvm-svn: 254320

Adding Hwloc library option for affinity mechanism These changes allow libhwloc to be used as the topology discovery/affinity mechanism for libomp. It is supported on Unices. The code additions: * Canonicalize KMP_CPU_* interface macros so bitmask operations are implementation independent and work with both hwloc bitmaps and libomp bitmaps. So there are new KMP_CPU_ALLOC_* and KMP_CPU_ITERATE() macros and the like. These are all in kmp.h and appropriately placed. * Hwloc topology discovery code in kmp_affinity.cpp. This uses the hwloc interface to create a libomp address2os object which the rest of libomp knows how to handle already. * To build, use -DLIBOMP_USE_HWLOC=on and -DLIBOMP_HWLOC_INSTALL_DIR=/path/to/install/dir [default /usr/local]. If CMake can't find the library or hwloc.h, then it will tell you and exit. Differential Revision: http://reviews.llvm.org/D13991 llvm-svn: 254320

Large Refactor of CMake build system This commit improves numerous functionalities of the OpenMP CMake build system to be more conducive with LLVM's build system and build philosophies. The CMake build system, as it was before this commit, was not up to LLVM's standards and did not implement the configuration stage like most CMake based build systems offer (check for compiler flags, libraries, etc.) In order to improve it dramatically in a short period of time, a large refactoring had to be done. The main changes done with this commit are as follows: * Compiler flag checks - The flags are no longer grabbed from compiler specific directories. They are checked for availability in config-ix.cmake and added accordingly inside LibompHandleFlags.cmake. * Feature checks were added in config-ix.cmake. For example, the standard CMake module FindThreads is probed for the threading model to use inside the OpenMP library. * OS detection - There is no longer a LIBOMP_OS variable, OS-specifc build logic is wrapped around the WIN32 and APPLE macros with !(WIN32 OR APPLE) meaning a Unix flavor of some sort. * Got rid of vestigial functions/macros/variables * Added new libomp_append() function which is used everywhere to conditionally or undconditionally append to a list * All targets have the libomp prefix so as not to interfere with any other project * LibompCheckLinkerFlag.cmake module was added which checks for linker flags specifically for building shared libraries. * LibompCheckFortranFlag.cmake module was added which checks for fortran flag availability. * Removed most of the cruft from the translation between the perl+Makefile based build system and this one. The remaining components that they share are perl scripts which I'm in the process of removing. There is still more left to do. The perl scripts still need to be removed, and a config.h.in file (or similarly named) needs to be added with #cmakedefine lines in it. But this is a much better first step than the previous system.

Adding Hwloc library option for affinity mechanism These changes allow libhwloc to be used as the topology discovery/affinity mechanism for libomp. It is supported on Unices. The code additions: * Canonicalize KMP_CPU_* interface macros so bitmask operations are implementation independent and work with both hwloc bitmaps and libomp bitmaps. So there are new KMP_CPU_ALLOC_* and KMP_CPU_ITERATE() macros and the like. These are all in kmp.h and appropriately placed. * Hwloc topology discovery code in kmp_affinity.cpp. This uses the hwloc interface to create a libomp address2os object which the rest of libomp knows how to handle already. * To build, use -DLIBOMP_USE_HWLOC=on and -DLIBOMP_HWLOC_INSTALL_DIR=/path/to/install/dir [default /usr/local]. If CMake can't find the library or hwloc.h, then it will tell you and exit. Differential Revision: http://reviews.llvm.org/D13991 llvm-svn: 254320

Large Refactor of CMake build system This commit improves numerous functionalities of the OpenMP CMake build system to be more conducive with LLVM's build system and build philosophies. The CMake build system, as it was before this commit, was not up to LLVM's standards and did not implement the configuration stage like most CMake based build systems offer (check for compiler flags, libraries, etc.) In order to improve it dramatically in a short period of time, a large refactoring had to be done. The main changes done with this commit are as follows: * Compiler flag checks - The flags are no longer grabbed from compiler specific directories. They are checked for availability in config-ix.cmake and added accordingly inside LibompHandleFlags.cmake. * Feature checks were added in config-ix.cmake. For example, the standard CMake module FindThreads is probed for the threading model to use inside the OpenMP library. * OS detection - There is no longer a LIBOMP_OS variable, OS-specifc build logic is wrapped around the WIN32 and APPLE macros with !(WIN32 OR APPLE) meaning a Unix flavor of some sort. * Got rid of vestigial functions/macros/variables * Added new libomp_append() function which is used everywhere to conditionally or undconditionally append to a list * All targets have the libomp prefix so as not to interfere with any other project * LibompCheckLinkerFlag.cmake module was added which checks for linker flags specifically for building shared libraries. * LibompCheckFortranFlag.cmake module was added which checks for fortran flag availability. * Removed most of the cruft from the translation between the perl+Makefile based build system and this one. The remaining components that they share are perl scripts which I'm in the process of removing. There is still more left to do. The perl scripts still need to be removed, and a config.h.in file (or similarly named) needs to be added with #cmakedefine lines in it. But this is a much better first step than the previous system.

[OMPT] Windows Support for OMPT The problem is that the ompt_tool() function (which must be implemented by a performance tool) should be defined in the RTL as well to cover the case when the tool is not present in the address space of the process. This functionality is accomplished with weak symbols in Unices. Unfortunately, Windows does not support weak symbols. The solution in these changes is to grab the list of all modules loaded by the process and then search for symbol "ompt_tool()" within them. The function ompt_tool_windows() performs the search of the ompt_tool symbol. If ompt_tool is found, then its return value is used to initialize the tool. If ompt_tool is not found, then ompt_tool_windows() returns NULL and OMPT is thus, disabled. While doing these changes, the OMPT_SUPPORT detection in CMake was changed to test for the required featuers for OMPT_SUPPORT, namely: builtin_frame_address() existence, weak attribute existence and psapi.dll existence. For LIBOMP_HAVE_OMPT_SUPPORT to be true, it must be that the builtin_frame_address() intrinsic exists AND one of: either weak attributes exist or psapi.dll exists. Also, since Process Status API is used I had to add new dependency -- psapi.dll to the library dependency micro test. Differential Revision: http://reviews.llvm.org/D14027 llvm-svn: 251654
