Compile SDK11 with ARM Compiler Version 6

[Christopher]

I would like to use the latest ARM Compiler Version 6 (armclang) because I need some features of the C++11 language.

Is it possible to use the latest ARM Compiler Version 6 to compile the SDK 11 ? Which flags should we use to be compatible with all macros currently available for GCC and armcc ?

In future SDK releases, will this compiler be officially supported ?

is armclang related to clang, as in the LLVM compiler? If so, it's very likely not going to work at all. clang/llvm fails to generate proper softdevice calls in release mode for reasons I and others have gone into at length on other threads. You can't currently use clang to compile so if armclang is based on LLVM, give up.

I noticed the same thing when trying -O2 or -O3. -O1 worked fine, anything over this failed (including Os/Oz). I really like clang as a compiler and the features that it provides, and I'll try to push for a deeper investigation of the llvm toolchain internally. Since Keil v5.20/DS-5/SES all have the option to use llvm, it will become more widespread in the near future.
