| 12 # if "$entry_count" is ever changed and the .inc files regenerated then | |
| 13 # the following issues need to be addressed: | |
| 14 # | |
| 15 # 1) The current Linux ARM code has a limitation of only having 256-3 stubs, | |
| 16 # as a result of the limitations of immediate values in ARM assembly. | |
| 17 # | |
| 18 # This number is verified by the IDL parser in xpcom/idl-parser/xpidl.py, as | |
| 19 # well as in xpcom/reflect/xptinfo/src/xptiInterfaceInfoManager.cpp, to | |
| 20 # prevent generating interfaces or loading xpt files that would cause the | |
| 21 # stubs to run off the entries. | |
| 22 # If you change this number, please update that location. | |
| 23 | |
| 24 # 3 entries are already 'used' by the 3 methods of nsISupports. | |
| 25 # 3+247+5=255 This should get us in under the Linux ARM limitation | |
