35 * But look at the definitions below to see how much is really
36 * allocated. The numbers above are the maximums allowed. We might
39 * Almost. We leave a hole of size 32 KB at the end of each of these
43 * It may be possible to increase the size of the dynamic spaces even
44 * further, but Casper H.S. Dik says shared libraries are loaded
45 * directly under the stack, so we need to leave some space for the C
46 * stack and shared libraries. He also says the top of stack is
47 * 0xffbf0000 for Ultrasparcs in Solaris 7+, but it's 0xf0000000 for
48 * sun4m (and 4u in S2.6-) 0xe0000000 for sun4d)
50 * Shared libraries can be mapped anywhere there's room.

62 * SPARSE_BLOCK_SIZE (32 KB) boundary. (See seg_force_resident in
63 * sunos-os.c. If not, then mapping the holes causes segfaults in
66 * Sparse block size must be larger than the system page size.

78 * See the notes there!
81 #define FOREIGN_LINKAGE_SPACE_START (LinkageSpaceStart)
84 * This allows for about 510K symbols (assuming each entry is 16 bytes
85 * long). Hope that's enough! Make sure this doesn't overlap the
86 * READ_ONLY_SPACE_START!

112 * On Solaris 10, Martin Rydstrom reports that subtracting off
113 * SPARSE_BLOCK_SIZE causes CMUCL not to work (GC lossage). But
114 * specifying -dynamic-space-size 256 works fine. I don't understand
115 * how that can be, but we lets not subtract it off.

127 * double the heap size.
