From: "Gabriel F. T. Gomes" <gabrielftg@linux.ibm.com> Changes since v1: - Added comment on the redefinition of libm_alias_float128_other_r_ldbl. -- 8< -- On powerpc64le, the libm_alias_float128_other_r_ldbl macro is used to create an alias between totalorderf128 and __totalorderlieee128, as well as between the totalordermagf128 and __totalordermaglieee128. However, the totalorder* and totalordermag* functions changed their parameter type since commit ID 42760d764649 and got compat symbols for their old versions. With this change, the aforementioned macro would create two conflicting aliases for __totalorderlieee128 and __totalordermaglieee128. This patch avoids the creation of the alias between the IEEE long double symbols (__totalorderl*ieee128) and the compat symbols, because the IEEE long double functions have never been exported thus don't need such compat symbol. --- sysdeps/ieee754/ldbl-128/s_totalorderl.c | 9 +++++++++ sysdeps/ieee754/ldbl-128/s_totalordermagl.c | 9 +++++++++ 2 files changed, 18 insertions(+)
