From 915215be09d492d167fa2a0d0c4d3f75cfb40157 Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Wed, 9 Oct 2013 15:55:17 +0000 Subject: [PATCH] monitor.c: Don't install a deprecated_xfer_memory method. This removes another yet instance of a deprecated_xfer_memory user. Tested by building a --enable-targets=all gdb, on x86-64 Fedora 17. gdb/ 2013-10-09 Pedro Alves * monitor.c (monitor_write_memory, monitor_write_memory_bytes) (monitor_write_memory_longlongs, monitor_write_memory_block): Constify 'myaddr' parameter. (monitor_xfer_memory): Adjust interface as monitor_xfer_partial helper. (monitor_xfer_partial): New function. (init_base_monitor_ops): Don't install a deprecated_xfer_memory hook. Install a to_xfer_partial hook. --- gdb/ChangeLog | 11 +++++++++++ gdb/monitor.c | 48 +++++++++++++++++++++++++++++++++--------------- 2 files changed, 44 insertions(+), 15 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 51f9b43c8c7..d2fb9999268 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,14 @@ +2013-10-09 Pedro Alves + + * monitor.c (monitor_write_memory, monitor_write_memory_bytes) + (monitor_write_memory_longlongs, monitor_write_memory_block): + Constify 'myaddr' parameter. + (monitor_xfer_memory): Adjust interface as monitor_xfer_partial + helper. + (monitor_xfer_partial): New function. + (init_base_monitor_ops): Don't install a deprecated_xfer_memory + hook.
