| michael@0 | 12 | # if "$entry_count" is ever changed and the .inc files regenerated then |

| michael@0 | 14 | # |
| michael@0 | 15 | # 1) The current Linux ARM code has a limitation of only having 256-3 stubs, |
| michael@0 | 16 | # as a result of the limitations of immediate values in ARM assembly. |
| michael@0 | 17 | # |
| michael@0 | 18 | # This number is verified by the IDL parser in xpcom/idl-parser/xpidl.py, as |
| michael@0 | 19 | # well as in xpcom/reflect/xptinfo/src/xptiInterfaceInfoManager.cpp, to |
| michael@0 | 20 | # prevent generating interfaces or loading xpt files that would cause the |
| michael@0 | 21 | # stubs to run off the entries. |
| michael@0 | 22 | # If you change this number, please update that location. |
| michael@0 | 23 | |
| michael@0 | 24 | # 3 entries are already 'used' by the 3 methods of nsISupports. |
| michael@0 | 25 | # 3+247+5=255 This should get us in under the Linux ARM limitation |
