+# 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.
