trying build own non-gnu cross-platform c++ environment, have faced fact don't understand basics of stack unwinding. environment build follows: libc++ ← libc++abi ← libunwind (or other unwinder). i've found libc++abi contains kind of libunwind, doesn't use on linux. comments understood, it's special libunwind: llvm stack unwinder supports darwin , arm not x86_64 - , it's confusing. how come cpu architecture affects stack unwinding process? also know following stack unwinders: glibc built-in. libc++abi llvm libunwind. gnu libunwind (from savanna). questions: how platform or cpu architecture affects stack unwinding process? why have many stack unwinders - , not single one? what kind of unwinders exist , difference between them? expectations answer: i expect answer covers topic whole, not separate points on each question. fundamentally, stack layout compiler. can lay out stack in whatever way thinks best. language standar
