From 141458b172288d5b15f104f6cba5d26e78a22c23 Mon Sep 17 00:00:00 2001 From: Daniel Jacobowitz Date: Tue, 15 Aug 2006 18:17:57 +0000 Subject: * remote.c (remote_write_bytes): Take a const buffer argument. Do the checks from remote_xfer_memory. (remote_read_bytes): Do the checks from remote_xfer_memory. (remote_xfer_memory): Remove checks pushed into lower level functions. (remote_xfer_partial): Call remote_write_bytes and remote_read_bytes directly. * remote.h (remote_write_bytes): Update prototype. --- gdb/ChangeLog | 11 +++++++++++ gdb/remote.c | 46 ++++++++++++++++++++++++---------------------- gdb/remote.h | 3 ++- 3 files changed, 37 insertions(+), 23 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 38ffcab25c7..4dfbd9b7f15 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,14 @@ +2006-08-15 Daniel Jacobowitz + + * remote.c (remote_write_bytes): Take a const buffer argument. + Do the checks from remote_xfer_memory. + (remote_read_bytes): Do the checks from remote_xfer_memory. + (remote_xfer_memory): Remove checks pushed into lower level + functions. + (remote_xfer_partial): Call remote_write_bytes and remote_read_bytes + directly. + * remote.h (remote_write_bytes): Update prototype. + 2006-08-11 Andrew Stubbs * NEWS: Add 'set trace-commands' command. diff --git a/gdb/remote.c b/gdb/remote.c index adafdc7245e..654509457b1 100644 --- a/gdb/remote.c +++ b/gdb/remote.c @@ -3853,7 +3853,7 @@ check_binary_download (CORE_ADDR addr) error.
