Versions of libraries used in armclang

Hello, 

due to our software process we need to know which library versions are Included in ARMClang 6.10

Due to Arm® Compiler armclang Reference Guide (https://developer.arm.com/docs/100067/0610, p. 1-21), I see (attached picture) that ARM-C-library, ARM-C++-library and libc++ are used.

Where can I find information which version of the library is used? Is it possible to trace it with defines, like __LIBCXX_VERSION? I didn't found any information due to which versions of the library are included in ARMclang 6.10

If I check <InstallPath>\ARM\ARMCLANG\sw\info\thirdpartylicenses, I find the licenses but not the versiosn.

Thanks a lot.
