core_xfer_shared_libraries and core_xfer_shared_libraries_aix returns ULONGEST
This patch documents the return value of core_xfer_shared_libraries_aix
and core_xfer_shared_libraries gdbarch methods, and changes return
type to ULONGEST from LONGEST.
In a following patch, core_xfer_partial. is changed to check their
return values and return an appropriate target_xfer_status.
gdb:
2014-02-07 Yao Qi <yao@codesourcery.com>
* gdbarch.sh (core_xfer_shared_libraries): Returns ULONGEST. Add
comments.
(core_xfer_shared_libraries_aix): Likewise.
* gdbarch.c, gdbarch.h: Regenerated.
* i386-cygwin-tdep.c (windows_core_xfer_shared_libraries): Return
ULONGEST. Change 'len_avail' type to ULONGEST.
* rs6000-aix-tdep.c (rs6000_aix_ld_info_to_xml): Likewise.
* rs6000-aix-tdep.h (rs6000_aix_ld_info_to_xml): Update
declaration.
(rs6000_aix_core_xfer_shared_libraries_aix): Return ULONGEST.
