From: Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com> The API doesn't change, i.e. compilers using a long double format compatible with the IEEE 128-bit extended precision format are redirected from *l functions to __*ieee128 symbols using the same mechanism already used with -mlong-double-64 for complex math functions. 2018-06-06 Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com> * math/complex.h [__HAVE_DISTINCT_FLOAT128 && !__HAVE_FLOAT128_UNLIKE_LDBL]: Redirect long double functions to __*ieee128. --- math/complex.h | 28 ++++++++++++++++++++++++++-- 1 file changed, 26 insertions(+), 2 deletions(-)
