Replace some $ARCH_{get,set}_pc with linux_{get,set}_pc_64bit
This patch is the follow-up of
https://sourceware.org/ml/gdb-patches/2016-01/msg00164.html to provide
linux_{get,set}_pc_64bit functions.
Rebuild GDBserver with tilegx-linux-gcc. Not tested.
I think about pc in Tile-GX a little bit. Looks current Tile-GX
supports debugging 32-bit program (multi-arch), but PC is always
64-bit. See this thread
https://sourceware.org/ml/gdb-patches/2013-02/msg00113.html
and GDBserver reads PC as 64-bit through ptrace. However, if
the inferior is 32-bit, the PC in the target description and
regcache is 32-bit, so only 32-bit contents are sent back GDB.
Anyway, Tile-GX GDBserver may have some problems here, but this
patch doesn't change anything.
gdb/gdbserver:
2016-01-18 Yao Qi <yao.qi@linaro.org>
* linux-low.c (linux_set_pc_64bit): New function.
(linux_get_pc_64bit): New function.
* linux-low.h (linux_set_pc_64bit, linux_get_pc_64bit):
Declare.
* linux-sparc-low.c (debug_threads): Remove declaration.
(sparc_get_pc): Remove.
(the_low_target): Use linux_get_pc_64bit instead of
sparc_get_pc.
* linux-tile-low.c (tile_get_pc, tile_set_pc): Remove.
(the_low_target): Use linux_get_pc_64bit and
linux_set_pc_64bit.
