11 * fpa11.h - Add documentation

14 * softfloat.c - Remove float128

18 * The FPA11 structure is not a kernel-
19 It is used by users of ptrace to exa
20 floating point registers. Therefore
21 FPA11 structure (size or position of
22 within) have to be well thought out.

24 * Since 128-bit float requires the FPA
25 size, it has been removed. 128-bit

34 * fpmodule.c - Changed version number

44 * I discovered several bugs. First an

48 user_fp is smaller. This meant that

53 * user_fp and FPA11 have now been harm
