[Beignet] [PATCH 5/5] Backend: Add support for LLVM 3.9 release
Xiuli Pan
xiuli.pan at intel.com
Thu Aug 4 06:34:06 UTC 2016
From: Pan Xiuli <xiuli.pan at intel.com>
LLVM 3.9 changes a lot from 3.8, modify on:
1. API getGlobalContext was removed, add GBEGetLLVMContext instead
2. API LLVMLinkModules was removed, use LLVMLinkModules2 instead.
3. LLVMLinkModules2 now will delete src module for default, clone all
src module and kernel names.
4. Few LLVM pass refine, change include headers and creadpass API.
5. clang refine image type name, change llvminfo check for image.
6. clang change kernel arg info metadata and some other metadata to
function metadata, refine metedata query function logic.
7. clang default define most cl_khr_* macro, need to undef them first.
8. SPIR mangle was changed by a fix patch for Itanium mangle, now most
SPIR can not be recognized by LLVM 3.9.
