|
|
|
|
* Problems in cross-compiling PUPA are fixed.
|
|
|
|
* Use -mrtd and -mregparm=3 to reduce the generated code sizes. This
|
|
means that any missing prototypes could be fatal. Also, you must take
|
|
care when writing assembly code. See the comments at the beginning of
|
|
startup.S, for more details.
|
|
|
|
* New utility, ``pupa-setup''. This sets up PUPA to make it bootable
|
|

|
|
part of the core image and decompressing itself at boot time. The
|
|
currently used algorithm is LZO (more precisely, LZO1X-999). So you
|
|
have to install LZO to build PUPA. See
|
|
<http://www.oberhumer.com/opensource/lzo/>, for more information.
