* tilegx-linux-tdep.c (tilegx_linux_supply_regset): Delete
function. Move logic to...
(tilegx_linux_regmap): ... this new register map.
(tilegx_linux_regset): Refer to register map, replace supply
method by regcache_supply_regset, and add collect method.
* tilegx-tdep.h (enum tilegx_regnum): New enum value
TILEGX_FIRST_EASY_REGNUM.
2014-08-07 Andreas Arnez <arnez@linux.vnet.ibm.com>
* score-tdep.c (score7_linux_supply_gregset): Reduce to small stub
