23: * This module only exists because I don't know how to get the silly C compiler
24: * and/or linker to generate data areas that are aligned on a particular boundary.
25: * And, this stuff is in the V=R mapped area.
26: *
27: * Do the following for each:
28: *
29: * .size name,size-in-bytes
30: * .type area-name,@object
31: * .globl area-name
32: * .align power-of-two
33: * area-name:
34: * .set .,.+size-in-bytes
35: *
36: * So long as I'm being pedantic, always make sure that the most aligned,
37: * i.e., the largest power-of-twos, are first and then descend to the smallest.
38: * If you don't, and you are not careful and hand calculate, you'll end up
39: * with holes and waste storage. I hate C.
40: *
41: * Define the sizes in genassym.c
