[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [patch 02/10] add libelf: an ELF binary parser library.
This patch adds a library with a small collection of helper functions
to parse and load elf binaries. The library handles endianess and
elfsize at runtime.
The patch also shuffles around the include files a bit. Now there is
*one* include file holding all the elf structures
(xen/include/public/elfstructs.h) which is included by everyone who
needs them.
It's dead code with this patch only, putting the code into use happens
in followup patches.
