The libmeminfo extracts the memory configuration of an ELF file. This memory configuration is stored inside a binary at link-time if the linker-script has the command CREATE_MEMINFO_TABLE. This new command and its documentation are available once the patch is applied against the GNU Binutils.

The file meminfo.h comments the API, and the file mind.c is a very good example on how to use this library. You can test the program mind against the file test.elf:

mem4data   : origin = 0x00000000, length = 0x00010000, flags = 0x00000012, not_flags = 0x00000000 [wi]
mem4text   : origin = 0x40000000, length = 0x00300000, flags = 0x00000014, not_flags = 0x00000000 [xi]

If you don't want to use the local libELF to build the libmeminfo, set the parameter --disable-local-libelf during the configuration process or set the variable enable_local_libelf to no in the $CONFIG_SITE file.
