| # Some files which need to go both into libc and libm have external |
| # dependencies which need to be resolved differently for libc |
| # vs. libm. For example, inside libc, __libm_error_support needs to |
| # resolve to HIDDEN_JUMPTARGET(__libm_error_support) whereas within |
| # libm it always resolves to __libm_error_support. Such files need to |
| # be compiled twice. Fortunately, math/Makefile already has logic to |
| # support this: if a file starts with "s_", make will automatically |
| # generate a matching file whose name starts with "m_" which simply |
| # includes the corresponding "s_" file. |
