Modified files:
sys/sparc64/include fp.h
sys/sparc64/sparc64 cache.c fp.c trap.c
Added files:
sys/sparc64/include fsr.h
Log:
1. Split fp.h into fp.h and fsr.h so that the latter can be included
in asm files.
2. Temporarily cause subnormal operands in floating point operations
to be treated as zeros so that comlpetion of the operation does not
need to be emulated.
3. Catch fp_exception_other and correctly skip over the unfinished
instruction, but basically ignore them. Emulating the instruction
is not yet supported.
4. Zero td_retval[1] as well in syscall().
