dos/exe
|
|
|
|
|
-------
|
|
|
|
|
* normal dos/exes with new exe headers
|
|
|
|
|
* max ~24000 relocation records (...should be enough for everyone ;-)
|
|
|
|
|
* exe + sys combined images

---------

2000-05-19 16:04:55 +00:00
|
|
|
* 16-bit selector alias fixups
|
2008-04-26 06:48:13 +00:00
|
|
|
* 16-bit offset relocation for objects larger than 4 KiB
|

If you need any of the above (they're very rare), send us an URL of a
|
2000-05-19 16:04:55 +00:00
|
|
|
test file.
|
|
|
|
|
|
|
|
|
|
* 16-bit objects are not loaded into DOS memory
|
|
|
|
|
* There is still a problem with the wdosx extender: if you compress a
|
2000-12-20 12:03:14 +00:00
|
|
|
watcom/le file which does NOT contain the wdosx extender, and after this
|
2000-05-19 16:04:55 +00:00
|
|
|
you bind the wdosx stub to the compressed file, then it will work.
|
|
|
|
|
Otherwise it won't.
|
|
|
|
|
* unpacked pmwlite compressed programs might not work when compressed
|
2000-12-20 12:03:14 +00:00
|
|
|
with UPX (this is a bug in pmwunlite)

|
* writable shared sections (`--force' *may* work)
|
2000-05-19 16:04:55 +00:00
|
|
|
* certificates in the image
|
2000-12-20 12:03:14 +00:00
|
|
|
* compressing files which contain a big BSS requires lots of memory

during compression
