[PATCH] D134938: Use builtins in <math.h>

[Hubert Tong via Phabricator via llvm-commits]

hubert.reinterpretcast added inline comments.


================
Comment at: libcxx/include/math.h:800-802
+inline _LIBCPP_HIDE_FROM_ABI long double acos(long double __x) _NOEXCEPT {
+#      if __has_builtin(__builtin_acosl) && !defined(_AIX)
+  return __builtin_acosl(__x);
----------------
LLVM on AIX currently only supports the case where `double` and `long double` have the same format; that may explain why there is no `__builtin_acosl`?
