John Reiser ea2a190bd1 ELF2 main programs pass src/testsuite and upx-testsuite-v2 
Decompressing lzma required many adjustments.
Backwards compatibility probably is broken for
    stub/amd64-win64.pe.h
    stub/arm64-win64.pe.h
Also: shared libraries need memfd_create.

Markus F.X.J. Oberhumer a1d090a6fd src/stub: add a "clang-format off" directive 2023-10-15 10:55:15 +02:00
John Reiser adb0ca8250 Many changes for ELF shared libraries on Linux and Android 
Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)
required extensive changes.  But the bonus is the infrastructure
to support a different (de-)compression algorithm for each PT_LOAD.

https://github.com/upx/upx/issues/609   armv7 .so on Android
