| These are in-progress notes for the upcoming LLVM 3.8 release. You may |

| |
| |
| Introduction |
| ============ |
| |
| This document contains the release notes for the LLVM Compiler Infrastructure, |
| release 3.8. Here we describe the status of LLVM, including major improvements |
| from the previous release, improvements in various subprojects of LLVM, and |
| some of the current users of the code. All LLVM releases may be downloaded |
| from the `LLVM releases web site <http://llvm.org/releases/>`_. |
| |
| For more information about LLVM, including information about the latest |
| release, please check out the `main LLVM web site <http://llvm.org/>`_. If you |
| have questions or comments, the `LLVM Developer's Mailing List |
| <http://lists.llvm.org/mailman/listinfo/llvm-dev>`_ is a good place to send |
| them. |
| |
| Note that if you are reading this file from a Subversion checkout or the main |
| LLVM web page, this document applies to the *next* release, not the current |
| one. To see the release notes for a specific release, please see the `releases |
| page <http://llvm.org/releases/>`_. |
| |
| Non-comprehensive list of changes in this release |
| ================================================= |
| * With this release, the minimum Windows version required for running LLVM is |
| Windows 7. Earlier versions, including Windows Vista and XP are no longer |
| supported. |
| |
| * With this release, the autoconf build system is deprecated. It will be removed |
| in the 3.9 release. Please migrate to using CMake. For more information see: |
| `Building LLVM with CMake <CMake.html>`_ |
| |
| * The C API function LLVMLinkModules is deprecated. It will be removed in the |
| 3.9 release. Please migrate to LLVMLinkModules2. Unlike the old function the |
| new one |
| |
| * Doesn't take an unused parameter. |
| * Destroys the source instead of only damaging it. |
| * Does not record a message. Use the diagnostic handler instead. |
| |
| * The C API functions LLVMParseBitcode, LLVMParseBitcodeInContext, |
| LLVMGetBitcodeModuleInContext and LLVMGetBitcodeModule have been deprecated. |
| They will be removed in 3.9. Please migrate to the versions with a 2 suffix. |
| Unlike the old ones the new ones do not record a diagnostic message. Use |
| the diagnostic handler instead. |
| |
| * The deprecated C APIs LLVMGetBitcodeModuleProviderInContext and |
| LLVMGetBitcodeModuleProvider have been removed. |
| |
| * The deprecated C APIs LLVMCreateExecutionEngine, LLVMCreateInterpreter, |
| LLVMCreateJITCompiler, LLVMAddModuleProvider and LLVMRemoveModuleProvider |
| have been removed. |
| |
| * With this release, the C API headers have been reorganized to improve build |
| time. Type specific declarations have been moved to Type.h, and error |
| handling routines have been moved to ErrorHandling.h. Both are included in |
| Core.h so nothing should change for projects directly including the headers, |
| but transitive dependencies may be affected. |
| |
| .. NOTE |
| For small 1-3 sentence descriptions, just add an entry at the end of |
| this list. If your description won't fit comfortably in one bullet |
| point (e.g. maybe you would like to give an example of the |
| functionality, or simply have a lot to talk about), see the `NOTE` below |
| for adding a new subsection. |
| |
| * ... next change ... |
| |
| .. NOTE |
| If you would like to document a larger change, then you can add a |
| subsection about it right here. You can copy the following boilerplate |
| and un-indent it (the indentation causes it to be inside this comment). |
