This reverts commit 47ed8656db8800f3ad20a40eb2c4e9ef3dc891e3. Conflicts: libguile/foreign.c
2011-10-24add SCM_HEAP_OBJECT_BASEAndy Wingo1-1/+1
* libguile/tags.h (SCM_HEAP_OBJECT_BASE): New macro. Given a SCM, returns a pointer to the start of its memory area on the heap. * libguile/bytevectors.c: * libguile/fluids.c: * libguile/foreign.c: * libguile/gc.h: * libguile/guardians.c: * libguile/numbers.h: * libguile/ports.c: * libguile/smob.c: * libguile/struct.c: * libguile/weak-set.c: * libguile/weak-table.c: * libguile/weak-vector.c: Use it.
2011-10-24add SCM_HEAP_OBJECT_PAndy Wingo1-3/+3
* libguile/tags.h (SCM_HEAP_OBJECT_P): New macro, an alias for SCM_NIMP. * libguile/arrays.c: * libguile/debug.c: * libguile/foreign.c: * libguile/gdbint.c: * libguile/guardians.c: * libguile/list.c: * libguile/modules.c: * libguile/options.c: * libguile/smob.c: * libguile/validate.h: * libguile/weak-set.c: * libguile/weak-table.c: * libguile/weak-vector.c: Use it instead of SCM_NIMP or !SCM_IMP.
2011-10-24add SCM_{PACK,UNPACK}_POINTERAndy Wingo1-2/+2
* libguile/tags.h (SCM_UNPACK_POINTER, SCM_PACK_POINTER): New macros. The old SCM2PTR and PTR2SCM were defined in such a way that round-tripping through a pointer could lose precision, even in the case in which you weren't interested in actually dereferencing the pointer, it was simply that you needed to plumb a SCM through APIs that take pointers. These new macros are more like SCM_PACK and SCM_UNPACK, but for pointer types. The bit representation of the pointer should be the same as the scm_t_bits representation. * libguile/gc.h (PTR2SCM, SCM2PTR): Remove support for (old) UNICOS pointers. We are going to try tagging the SCM object itself in the future, and I don't think that keeping this support is worth its cost. It probably doesn't work anyway. * libguile/backtrace.c: * libguile/bytevectors.c: * libguile/continuations.c: * libguile/fluids.c: * libguile/foreign.c: * libguile/gc.h: * libguile/guardians.c: * libguile/hashtab.c: * libguile/load.c: * libguile/numbers.c: * libguile/ports.c: * libguile/smob.c: * libguile/strings.c: * libguile/symbols.c: * libguile/vm.c: * libguile/weak-set.c: * libguile/weak-table.c: * libguile/weak-vector.c: Update many sites to use the new macros.
2011-10-24remove weak pairs, rewrite weak vectorsAndy Wingo1-0/+207
* libguile/weak-vector.c: * libguile/weak-vector.h: Renamed from weaks.[ch]. Remove weak pairs. They were not safe to access with `car' and `cdr'. Remove weak alist vectors, as we have weak tables and sets. Reimplement weak vectors, moving the implementation here. * libguile/vectors.c: * libguile/vectors.h: Remove the extra header word. Use scm_c_weak_vector_ref / scm_c_weak_vector_set_x to access weak vectors. * libguile/snarf.h: Remove the extra header word in vectors. * libguile/threads.c (do_thread_exit, fat_mutex_lock, fat_mutex_unlock): Instead of weak pairs, store thread-owned mutexes in a list of one-element weak vectors. * libguile/guardians.c (finalize_guarded): Similarly, store object guardians in a list of one-element weak vectors. * libguile/modules.c (scm_module_reverse_lookup): We no longer need to handle the case of weak references. * libguile/print.c (iprin1): Use the standard vector accessor to print vectors. * libguile.h: * libguile/Makefile.am: * libguile/gc-malloc.c: * libguile/gc.c: * libguile/goops.c: * libguile/init.c: * libguile/objprop.c: * libguile/struct.c: Update includes. * module/ice-9/weak-vector.scm: Load weak vector definitions using an extension instead of %init-weaks-builtins. * test-suite/tests/weaks.test: Use the make-...-hash-table names instead of the old alist vector names.
