Markus F.X.J. Oberhumer 021c8db58a Welcome 2018. 2018-01-19 10:55:32 +01:00
John Reiser c34fe09a79 Revamp --android-shlib 
Android "Oreo" wants to deal with ElfXX_Shdr[].  So splice 4KiB into PT_LOAD[0]
with an "extra" copy of them.  This requires careful relocation processing.
It also costs a page at run time, and an average of a page in the file
(depending on fragmentation at the boundary between r-x and rw- .)

The entry point points to the unfilter and uncompress routines.
Somehow _start has been lost.
