| // really need __ldexp_cexp, but it does need __ldexp_exp, and both functions |
| // are defined in the same C file. complex.h doesn't declare cimag/creal when |
| // building libandroid_support, because the functions are only available |
| // starting with M, and libandroid_support is compiled for the oldest supported |
| // NDK API. |
| // |
| // The two functions are trivial (and have __builtin_{cimag,creal} |
| // equivalents). Clang inlines calls to these functions even with -O0. |
