# 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.
