This version of zlib is modified for use within the Proxmark3 project.
|
|
Files from the original distribution which are not required for this
|
|
purpose are not included. All modifications can easily be found
|
|
by searching for #ifdef ZLIB_PM3_TUNED and #ifndef ZLIB_PM3_TUNED.
|
|
|
|
Current zlib base version is 1.2.11
|
|
|
|

|
|
|
|
Changes in 1.2.8.f-Proxmark3 (26 May 2015)
|
|
- disable decoding of fixed code blocks in deflate (eliminates the need
|

to store the fixed tree in RAM or ROM)
|
|
- disable generating fixed code blocks in inflate
|
|
- look harder for local optimum of consecutive matches and single literals
|
|
in inflate.

|
|
are not included
