When I worked there, we had to support ppc32/ppc64/x86/x86-64/arm32.
Now I'm guessing the dwarf format is: x86-64/arm32/arm64 with arm32 being legacy.
Back then we were also switching from GCC to LLVM, which at the time I thought was ludicrous because we'd be losing all of the flexibility in architectures GCC gave us. But I guess my worries were without merit.
