C TODO
|
|
C * Further optimize feed-in and wind-down code, both for speed and code size.
|
|
C * Handle low limb input and results specially, using a common stf8 in the
|
|
C epilogue.
|
|
C * Use 1 c/l carry propagation scheme in wind-down code.
|
|
C * Use extra pointer register for `up' to speed up feed-in loads.
|
|
C * Work out final differences with addmul_1.asm.
