37d6a34e58 MSVC is a nimrod. (All verions 10.0 through 14.1) 
"(4074): error C4146: unary minus operator applied to unsigned type, result still unsigned"
So what?  Many programmers are much better than the typical Microsoft coder.
The C standard GUARANTEES that unsigned arithmetic uses two's complement,
ignores overflow, and the result is what the hardware adder produces.

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- .)

19c2c1edcf Android 8.0 (Oreo) wants 0!=.e_shstrndx in a shared library 
https://github.com/upx/upx/issues/142
It should not matter what the .sh_name is; only the .sh_type matters.

0430e7931e PowerPC64 stub: on syscall, real Linux trashes r13 and below 
(except r1, r2, and input args!) So, r12 .e_entry for musl
must copy from a saved register.  [qemu-ppc64 doesn't trash registers!]

c652626a37 32-bit shared libs reduce Phdr[1].p_align to 4096, like 64-bit. 
This saves space when PAGE_SIZE is larger than 4096: MIPS, etc.

402c885987 Merge branch 'jreiser-elfstub' into devel 
New stub strategy on Linux:  Linux adds too many other segments
to the address space: [vdso], [sigpage], ...; and qemu might
arrange them differently.  Thus the only reliable mappings
are the PT_LOAD of the compressed file itself; all other
address space is unknown!  First, the compressed file uses
.bss to occupy all unused pages up to the original brk(0).
Then at run time, the stub gets another mapping of /proc/self/exe,
and uncompresses the user program on top of the original pages.
[*BSD unchanged for now?]

9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.
