From 0c012db1eb9c6b7c951e60cb74d0f6d7bb8738f9 Mon Sep 17 00:00:00 2001 From: Kevin Buettner Date: Tue, 10 Aug 2010 04:39:26 +0000 Subject: [PATCH] * remote-sim.c (gdbsim_xfer_inferior_memory): Replace `target_has_execution' check with `to_has_memory' check. (gdbsim_has_all_memory, gdbsim_has_memory): New functions. (init_gdbsym_ops): Initialize relevant fields of `gdbsim_ops' with `gdbsim_has_all_memory' and `gdbsim_has_memory'. --- gdb/ChangeLog | 8 ++++++++ gdb/remote-sim.c | 38 ++++++++++++++++++++++++++++++++------ 2 files changed, 40 insertions(+), 6 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index f051943..b803360 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,5 +1,13 @@ 2010-08-09 Kevin Buettner + * remote-sim.c (gdbsim_xfer_inferior_memory): Replace + `target_has_execution' check with `to_has_memory' check. + (gdbsim_has_all_memory, gdbsim_has_memory): New functions. + (init_gdbsym_ops): Initialize relevant fields of `gdbsim_ops' + with `gdbsim_has_all_memory' and `gdbsim_has_memory'. + +2010-08-09 Kevin Buettner + * remote-sim.c (program_loaded, gdbsim_desc, remote_sim_ptid) (resume_siggnal, resume_step): Move these static globals...
