9 | 9 | Sets memory allocator. |
10 | 10 | |
11 | | Currently, we have only one choice: the memory allocator in |
12 | | F<src/gc/alloc_resources.c>. |
13 | | |
14 | | In the future, we will have a C<--gc> command-line option which will enable |
15 | | the configurer to choose among several garbage collectors. |
| 11 | The C<--gc> command-line option enables the configurer to choose among |
| 12 | several garbage collectors. Current available options are: |
16 | 13 | |
17 | 14 | =over 4 |
18 | 15 | |
| 16 | =item ms |
| 17 | |
| 18 | Stop-the-world mark & sweep |
| 19 | |
| 20 | =item inf |
| 21 | |
| 22 | Infinite memory "collector" |
| 23 | |
| 24 | =item ms2 |
| 25 | |
| 26 | New style mark & sweep |
| 27 | |
| 28 | =item gms |
| 29 | |
| 30 | Generational M&S based on MS2 |
| 31 | |
19 | 32 | =back |
20 | 33 | |
| 34 | The choice is stored as C<gc_type> in C<%PConfig>, and available |
| 35 | (uppercased) as PARROT_GC_DEFAULT_TYPE in F<parrot/config.h> |
| 36 | |
| 37 | For backwards compatibility with parrot 3.1.0 and earlier, an empty |
| 38 | entry C<gc_flag> is maintained. (It used to be used in Makefiles to |
| 39 | append to the C compiler flags.) |
