* rs6000-tdep.c (IS_EFP_PSEUDOREG): Use correct constant for the EFP register set size. (efpr_pseudo_register_read): Use regcache_raw_read_part to read data from the VMX register. (efpr_pseudo_register_write): Use regcache_raw_write_part to read and write data from/to the VMX register. gdb/testsuite/ * gdb.arch/vsx-regs.exp: Add "vector_register1_vr" and "vector_register2_vr" test strings. Test the extended floating point registers (F32~F63). * lib/gdb.exp (skip_vsx_tests): Update compile flags for the IBM XL C compiler. Make the test program use a register provided by the compiler for the lxvd2x instruction.
