[cfe-dev] Build Clang with CMake and Intel Compiler

[Marvin Damschen]

Hello everyone,

keep failing to build Clang 3.4 with icpc, giving me 'Error: CFI
instruction used without previous .cfi_startproc' repeatedly. I tried
CMAKE_BUILD_TYPE=DEBUG and compiler flags -g and
-fno-asynchronous-unwind-tables, but it was no use. I am using icpc 14
(in GCC 4.8 compatibility mode) on Scientific Linux 6.4. I hope you can
help me out. LLVM without Clang succeeds to build.

On a related note, is there a canonical way to disable all the Sanitizers?

Best regards,
Marvin
