[llvm-dev] Compiling for AARCH64 (VMA=42)

[Simone Atzeni via llvm-dev]

Oh great thanks!

I actually have to do the same for PPC64 (44 and 46 bits).
Right now I am doing it in the same way you do for AARCH, so I am defining a SANITIZER_PPC64_VMA variable.

The problem is that the check needs to be done at compile time in order to select for example the right memory mapping in san_platform.h.

Do you guys have already an idea how to automize that? 

Best,
Simone
