Fixed now :) Thanks, Wei-cheng -- 2014-12-06 Wei-cheng Wang Ulrich Weigand * configure.tgt (powerpc*-*-linux): Add linux-record.o to gdb_target_obs. (ppc_linux_record_tdep, ppc64_linux_record_tdep): New for linux syscall record. (ppc_canonicalize_syscall, ppc_linux_syscall_record, ppc_linux_record_signal, ppc_init_linux_record_tdep): New functions. (ppc_linux_init_abi): Set process_record, process_record_signal. * ppc-tdep.h (struct gdbarch_tdep): Add ppc_syscall_record and ppc_linux_record_tdep to gdbarch_tdep. (ppc_process_record): New declaration. * rs6000-tdep.c (ppc_record_vsr, ppc_process_record_op4, ppc_process_record_op19, ppc_process_record_op31, ppc_process_record_op59, ppc_process_record_op60, ppc_process_record_op63, ppc_process_record): New functions. changelog for testsuite 2014-12-06 Wei-cheng Wang * lib/gdb.exp (supports_process_record): Return true for powerpc*-*-linux*. (supports_reverse): Likewise. commit b4cdae6fe51e532e0b1069c6960b14a610182d14 Author: Wei-cheng Wang Date: Sat Jan 17 14:30:33 2015 +0800 Reverse debugging for PowerPC.
