From 2ff29de43c961c76891a4fcacf929d544ae54b6b Mon Sep 17 00:00:00 2001 From: Jim Blandy Date: Thu, 29 May 2003 22:56:50 +0000 Subject: [PATCH] * linux-low.c (usr_store_inferior_registers): Transfer buf in PTRACE_XFER_TYPE-sized chunks, not int-sized chunks. Otherwise, if 'int' is smaller than PTRACE_XFER_TYPE, you end up throwing away part of the register's value. --- gdb/gdbserver/ChangeLog | 7 +++++++ gdb/gdbserver/linux-low.c | 4 ++-- 2 files changed, 9 insertions(+), 2 deletions(-) diff --git a/gdb/gdbserver/ChangeLog b/gdb/gdbserver/ChangeLog index 9df8a2a4807..7e998d094ed 100644 --- a/gdb/gdbserver/ChangeLog +++ b/gdb/gdbserver/ChangeLog @@ -1,3 +1,10 @@ +2003-05-29 Jim Blandy + + * linux-low.c (usr_store_inferior_registers): Transfer buf in + PTRACE_XFER_TYPE-sized chunks, not int-sized chunks.
