- Subject: [PATCH] Sparc long double is emulated in software, therefore usedbl-64's s_fma.c
I noticed this when I was about to add multiarch routines
for using FMA instructions on Sparc.
Other architectures using soft-fp or kernel FPU emulators for
long double support probably want to do the same thing.
