kib@ recently committed my implementations of cospi[fl], sinpi[fl], and tanpi[fl]. These functions have been extensively tested for float, double, and long double where long double is the Intel 80-bit long double (e.g., msun/ld80/s_sinpil.c). The 128-bit versions of these routines have not been tested (e.g., msun/ld128/s_sinpil.c)
kib pointed me to a system in the FreeBSD, which I have access to. Unfortunately, that system has double == long double, and can only test the support for the weak references. Is there a system with 128-bit long double that I can have access for some testing? -- Steve
