view packages/services/objloader/current/include/relocate_i386.h @ 2890:f8dd12428f1d
* cdl/objloader.cdl, src/objelf.c, src/relocate_ppc.c,
src/relocate_arm.c: Eliminate dependency on CYGPKG_IO_FILEIO when
the filesystem loader is not required.
* src/relocate_arm.c : Added relocation software for the ARM .
* src/relocate_i386.c : Added a structure containing the relocation names
for every architecture. Only used (and compiled in) for pretty printing.
* src/relocate_ppc.c :
* include/relocate_arm.h : New header file for src/relocate_arm.c
* cdl/objloader.cdl: Added the option to relocate for the ARM.
* src/objloader.c :
* src/objelf.c : Erased some redundant debug printout and improved the
readability of the rest.
* src/loader_memory.c : Added the code to allow the objloader package
to load libraries from ROM memory, instead from a file system. The various
sections of the library are the copied from ROM to RAM and relocated.
* include/loader_memory.h : New header file for src/loader_memory.c
* src/objloader.c : Added a line to include the loader_memory header
file and code to flush the cache when calling cyg_ldr_find_symbol().
* cdl/objloader.cdl: Added one check boxe for each of the supported ways
of loading libraries (two for now) so that the user can compile out the
loading methods not used.
