I use
cmake -G "Unix Makefiles" /home/jh/llvm-project/llvm
-DCLANG_TABLEGEN=/home/jh/llvm-project/llvm/out/stage1/bin/clang-tblgen
-DCMAKE_BUILD_TYPE=Release -DCMAKE_CXX_COMPILER=/home/jh/trunk-install/bin/g++
-DCMAKE_C_COMPILER=/home/jh/trunk-install/bin/gcc -DLL
VM_BINUTILS_INCDIR=/home/jh/binutils-install/include/ -DLLVM_BUILD_RUNTIME=No
-DLLVM_ENABLE_PROJECTS="clang;compiler-rt;lld" -DLL
VM_TABLEGEN=/home/jh/llvm-project/llvm/out/stage1/bin/llvm-tblgen
-DLLVM_TARGETS_TO_BUILD=X86 -DCMAKE_C_FLAGS_RELEASE="-O2 -fno-s trict-aliasing 
-flifetime-dse=1 -flto=auto -fno-semantic-interposition -fprofile-generate
-DNDEBUG" -DCMAKE_CXX_FLAGS_RELEASE="- O2  -flto=auto  -fno-strict-aliasing
-flifetime-dse=1 -fno-semantic-interposition -fprofile-generate -DNDEBUG"

I already checked that with that hunk in can_inline_edge_p commented out
the clang build and training run works.
Sadly clang segfaults with either strict aliasing or lifetime-dse
enabled.

Btw. how do you inject the CXXLFAGS to LLVM's cmake?
