When allocating the entire address space of an object, map an anonymous
...
region first (using the data/bss protection) covering it, then overlay
the text and data regions at the appropriate offsets within the region,
and then unmap any gap between the text and data.
The previous method of maping the entire address space with the actual
file object itself is incorrect, as it may extend past the end of the
file if the section alignment is large enough.
This bug was the source of the libposix failure on the SPARC and another
similar failure (with libc!) on the Alpha (failure was accompanied by
a "uvn_io: size check fired" message on the console).

First cut at an ELF shared loader. Originally from John Polstra's FreeBSD elf
...
kit, then hacked on by Matt Thomas <matt@3am-software.com>, then by me (to
make it work with new versions of the toolchain, etc.). This runs, but it's
in serious need of cleaning and/or a fair bit of reworking. See the README
file for more information, and a list of things to do.
