|
|
exist, all info needed by runtime loader must be first in .text, etc.)
|
|
* Linux /proc/self/exe now is preserved by default, by leaving behind
|
|
one page. New compress-time option --unmap-all-pages is available.

|
* dos/exe: LZMA is now also supported for 16-bit dos/exe. Please note that
|
|
you have to explicitly use '--lzma' even for '--ultra-brute' here
|
|
because runtime decompression is about 30 times slower than NRV -
|
|
which is really noticeable on old machines.
|
|
* dos/exe: fixed a rarely occurring bug in relocation handling
|
|
* win32/pe & arm/pe: better icon compression handling

|
|
via auto-detection of PT_NOTE or EI_OSABI
|
|

|
|
(only NRV2D is missing in thumb mode)

|
|
* major source code changes: the runtime decompression stubs are now
|
|
built from internal ELF objects
