3 Incremental Garbage Collector
4
5 * .cvsignore: Add .dbxrc and .gdbinit.
6
7 * .dbxrc: Remove.
8 * .dbxrc.in: New, used to generate .dbxrc: If newgc is enabled, do
9 not break on SIGBUS and SIGSEGV.
10 * .gdbinit: Remove.
11 * .gdbinit: New, used to generate .gdbinit: If newgc is enabled,
12 do not break on SIGBUS and SIGSEGV.
13
14 * Makefile.in.in: Add gc.c, newgc_objs and vdb_objs.
15

17 garbage_collect_1, GC related Lisp functions and variables. Left
18 in alloc.c are the allocation functions, the definition of
19 lrecords, the sweep functions of the old garbage collector, and
