Exactly, but they're not, and that's

[LLVMdev] [PATCH] Select correct embedded libclang_rt on Darwin
> When you decide to work on MachO/Darwin, I want to discuss the problems with ELF vs. EABI (http://llvm.org/PR18187).
Well, I'm doing it now to some extent (working on disentangling the
ARM backend's various uses of isTargetIOS, isTargetDarwin, isMoonFull
as a starting-point).
The thing is, the main advantage of Triples is that they're largely
GCC-compatible. Without that perspective, it's a mess: ELF/COFF/MachO,
AAPCS/APCS, RTABI/GNUABI, Little/big-endian, even 32/64-bit on targets
with both are all largely orth...
