This document contains the release notes for the LLVM Compiler Infrastructure,
-release 3.5. Here we describe the status of LLVM, including major improvements
+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/>`_.

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.
-* All backends have been changed to use the MC asm printer and support for the
- non MC one has been removed.
+* 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 ARM back-end now has the EHABI exception handling enabled by default. Use
- `-arm-disable-ehabi` to turn it off (both landing pads and unwind tables).
+* 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
-* Clang can now successfully self-host itself on Linux/Sparc64 and on
- FreeBSD/Sparc64.
+ * Doesn't take an unused parameter.
+ * Destroys the source instead of only damaging it.
+ * Does not record a message. Use the diagnostic handler instead.
-* LLVM now assumes the assembler supports ``.loc`` for generating debug line
- numbers. The old support for printing the debug line info directly was only
- used by ``llc`` and has been removed.
+* 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.
-* All inline assembly is parsed by the integrated assembler when it is enabled.
- Previously this was only the case for object-file output. It is now the case
- for assembly output as well. The integrated assembler can be disabled with
- the ``-no-integrated-as`` option,
+* The deprecated C APIs LLVMGetBitcodeModuleProviderInContext and
+ LLVMGetBitcodeModuleProvider have been removed.
-* llvm-ar now handles IR files like regular object files. In particular, a
- regular symbol table is created for symbols defined in IR files.
+* 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.
