* sample_lvos.asm _LVO definitions
*
* This is the .fd file for our sample library:
*
* Note - the slash in (D0/D1) means that a stub-maker can use MOVEM.L to
* load these registers from the stack, rather than using a separate MOVE
* instruction for each register. Alternately, something like (A0,D2) would
* show that a separate MOVE instruction is needed for each load.
*
* ##base _SampleBase
* ##bias 30
* ##public
* Double(n1)(D0)
* AddThese(n1,n2)(D0/D1)
* ##end
*
* After assembling,
* JOIN sample_stubs.o sample_lvos.o AS sample.lib
*
* Apps LINK with LIBRARY sample.lib when calling sample.library functions

*----- LIBINIT initializes an LVO value to -30 to skip the first four
*----- 6-byte required library vectors (Open, Expunge, etc)
LIBINIT
*----- LIBDEF assigns the current LVO value to a label, and then
*----- bumps the LVO value by -6 in preparation for next LVO label
*----- This assigns the value -30 to our first _LVO label
LIBDEF _LVODouble ;-30
