182 | ||
b2715b27 AW |
183 | Chained GDB smobs should have chained_gdb_smob as their first member. The |
184 | next,prev members of chained_gdb_smob allow for chaining gsmobs together so | |
185 | that, for example, when an objfile is deleted we can clean up all smobs that | |
186 | reference it. | |
ed3ef339 | 187 | |

188 | Eq-able GDB smobs should have eqable_gdb_smob as their first member. The |
189 | containing_scm member of eqable_gdb_smob allows for returning the same gsmob | |
190 | instead of creating a new one, allowing them to be eq?-able. | |
ed3ef339 | 191 | |
b2715b27 AW |
192 | All other smobs should have gdb_smob as their first member. |
193 | FIXME: dje/2014-05-26: gdb_smob was useful during early development as a | |
194 | "baseclass" for all gdb smobs. If it's still unused by gdb 8.0 delete it. | |
195 | ||
196 | IMPORTANT: chained_gdb_smob and eqable_gdb-smob are "subclasses" of | |
ed3ef339 DE |
197 | gdb_smob. The layout of chained_gdb_smob,eqable_gdb_smob must match |
198 | gdb_smob as if it is a subclass. To that end we use macro GDB_SMOB_HEAD | |
