[libcxx-commits] [PATCH] D119068: [libunwind] [sparc] Define _Unwind_Backtrace

[Arfrever Frehtes Taifersar Arahesis via Phabricator via libcxx-commits]

Arfrever added a comment.

During investigation for D118320 <https://reviews.llvm.org/D118320>, it was found that:

- GCC on PPC32 defines `__powerpc__`, but **not** `__ppc__` (Clang on PPC32 defines both)
- GCC on PPC64 defines both `__powerpc__` and `__powerpc64__` (Clang on PPC64 defines both)

So problem with functions such as `_Unwind_Backtrace` not being available is probably also present in libunwind built by GCC on PPC32.
Then `defined(__ppc__) || defined(__ppc64__) || defined(__powerpc64__)` could be merged into simple `defined(__powerpc__)`.
