Hi, all I am trying to use ld128 in x86_64 musl and i have some problems. Long double format is defined in arch/x86_64/bits/float.h and i am trying to change long double relevant macros. However, many long double functions still use double implementions(mostly "xxhl" functions). This is just a way to make musl compile and can be a problem in some cases. Simply changing the long double relevant macros can change ld80 into ld128 but this problem still exists. Is there any official support for long double math functions? Regards, Zhihao Gu.
