Modified files:
lib/libc/ia64 _fpmath.h
Log:
- Define LDBL_NBIT to be a mask indicating the position of the integer
bit in a long double. For architectures that don't have such a bit,
LDBL_NBIT is 0. This makes it possible to say `mantissa & ~LDBL_NBIT'
in places that previously used an #ifdef to select the right expression.
The optimizer should dispense with the extra arithmetic when LDBL_NBIT
is 0 anyway.
- Add an XXX comment for the big endian case.
