The functions used by the VSX regset to collect and supply registers from core files where incorrect. This patch changes the regset to use the standard regset collect/supply functions to fix this. The native target is also changed to use the same regset. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * ppc-linux-tdep.c (ppc_linux_vsxregset): New function. (ppc32_linux_vsxregmap): New global. (ppc32_linux_vsxregset): Initialize with ppc32_linux_vsxregmap, regcache_supply_regset, and regcache_collect_regset. * ppc-linux-tdep.h (ppc_linux_vsxregset): Declare. * ppc-linux-nat.c (supply_vsxregset, fill_vsxregset): Remove. (fetch_vsx_register, store_vsx_register): Remove. (fetch_vsx_registers): Add regno parameter. Get regset using ppc_linux_vsxregset. Use regset to supply registers. (store_vsx_registers): Add regno parameter. Get regset using ppc_linux_vsxregset. Use regset to collect registers. (fetch_register): Call fetch_vsx_registers instead of fetch_vsx_register. (store_register): Call store_vsx_registers instead of store_vsx_register. (fetch_ppc_registers): Call fetch_vsx_registers with -1 for the new regno parameter. (store_ppc_registers): Call store_vsx_registers with -1 for the new regno parameter. * rs6000-tdep.c (ppc_vsx_support_p, ppc_supply_vsxreget) (ppc_collect_vsxregset): Remove. gdb/testsuite/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * gdb.arch/powerpc-vsx-gcore.exp: New file.
