having to be in low memory. This is done be replacing the absolute branch instructions with equivalents that can branch anywhere. This adds a few extra instructions everywhere. Oh well. We also move the READ-ONLY space to a different location so we don't need the linker hacks and the darwinadjuster hacks. A basic cross-compile is necessary. Use boot-2006-11-1-cross-ppc.lisp for this. assembly/ppc/assem-rtns.lisp: compiler/ppc/call.lisp: o Replace BA instruction with BCTR. assembly/ppc/support.lisp: o Replace BLA instruction with BCTRL. o Replace BA instruction with BCTR. compiler/ppc/parms.lisp: lisp/ppc-validate.h: o Move the read-only space to #x04000000 instead of #x01000000. (This address appears to be free.) lisp/Config.ppc_darwin: o Comment out the linker flags for the CMUCLRO space. o Don't run the darwin-lispadjuster program. (We still build darwin-lispadjuster for now, but that should be removed eventually.)

Without this, hash tables were majorly broken because the hash vector was getting set to EQ_BASED_HASH_VALUE.

This is safe because the components are known to be properly scaled. compiler/float-tran.lisp: o Use %MAKE-DOUBLE-DOUBLE-FLOAT in %DOUBLE-DOUBLE-FLOAT to preserve the sign of the original float. This is safe because the components are known to be properly scaled. o Add a FLOAT-SIGN deftransform to handle DOUBLE-DOUBLE-FLOAT.

o Add a new slot to the hash-table structure for GC to use for linking weak tables together. (Previously we used the weak-p slot for this. Let's make it explicit, now. Plus, this allows us to use weak-p to indicate other types of weak tables, should they be implemented.) lisp/gencgc.c: o Update defstruct appropriately. o Use the new next-weak-table slot to chain the weak tables together. o Previously we scanned the weak tables in several places in the code. However, this scanning also removed entries. I don't think we want that because later scans could make a key valid. Thus: - Change scav_hash_entries so that it doesn't remove a hash-table entry unless told to. - Add new function to scavenge weak tables without removing a weak entry. - Adjust scan_weak_tables to remove weak entries. NOTE: When building, you'll be asked twice about the hash-table structure changing size. Just select the CLOBBER-IT restart in both cases.

would be broken but the value was still alive. Now only scan the weak pointers at the very end (like we used to), instead with the weak hash tables.

(key) hash tables. Then use it in several places where we need to scan the weak objects before closing the region. This fixes all of the problems with weak pointers and weak hash tables reported by Lynn Quam, cmucl-imp, 2006/07/04. Not 100% sure the solution is all correct, but it seems to be working.

lisp/gencgc.c: o Make last_free_page non-static so Lisp can see it. o Add get_page_table_info so Lisp can easily get at the flags and bytes_used slots of a page table entry. code/room.lisp: o Add gencgc-page-size constant. o Fix SPACE-BOUNDS for sparc and ppc with gencgc. The dynamic-space-free-pointer is something different, and we really wanted the last_free_page. o Update MAP-ALLOCATED-OBJECTS to handle gencgc (from sbcl). Unallocated pages are skipped, as well as anything at the end of a page that is not in use.
