37 * But look at the definitions below to see how much is really
38 * allocated. The numbers above are the maximums allowed. We might
41 * Almost. We leave a hole of size 32 KB at the end of each of these
45 * It may be possible to increase the size of the dynamic spaces even
46 * further, but Casper H.S. Dik says shared libraries are loaded
47 * directly under the stack, so we need to leave some space for the C
48 * stack and shared libraries. He also says the top of stack is
49 * 0xffbf0000 for Ultrasparcs in Solaris 7+, but it's 0xf0000000 for
50 * sun4m (and 4u in S2.6-) 0xe0000000 for sun4d)
52 * Shared libraries can be mapped anywhere there's room.

63 * Note: I'm not sure why, but the sizes must be on a
64 * SPARSE_BLOCK_SIZE (32 KB) boundary. (See seg_force_resident in
65 * sunos-os.c. If not, then mapping the holes causes segfaults in
68 * Sparse block size must be larger than the system page size.

77 * This space start better match the value of
78 * target-foreign-linkage-space-start defined in sparc/parms.lisp!
80 * See the notes there!
83 #define FOREIGN_LINKAGE_SPACE_START (LinkageSpaceStart)
86 * This allows for about 510K symbols (assuming each entry is 16 bytes
87 * long). Hope that's enough! Make sure this doesn't overlap the
88 * READ_ONLY_SPACE_START!

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

125 /* The maximum dynamic space that we can allocate */
128 * For GENCGC, we can use both dynamic spaces, so we get at least
129 * double the heap size.
