2011-11-10read_frame_register_value and big endian archesJoel Brobecker7-3/+131
The read_frame_register_value function as it was implemented introduced a regression on big-endian targets. The problem appears when trying to get the value of an entity stored inside a register, and when the size of the entity is smaller than the size of the register. In that case, we were always reading the first N bytes of the register, which is wrong for big-endian architectures, where we need to read the last N bytes of the register. gdb/ChangeLog: * findvar.c (read_frame_register_value): Read correct bytes from register on big-endian architectures. gdb/testsuite/ChangeLog: * gdb.ada/small_reg_param: New testcase.

2011-11-07[gdbserver] Fix watchpoint support on WindowsJoel Brobecker2-12/+19
Watchpoint support doesn't work anymore when using gdbserver on Windows. They just never trigger. The problem comes from the fact that we always set the debug registers to zero, no matter what. This in turn comes from the fact that we use i386_low_insert_watchpoint to compute the DR values: return i386_low_insert_watchpoint (&debug_reg_state, type, addr, len); This function saves the new values in debug_reg_state. However, the values we actually use when setting the DR registers are taken from two different globals: static unsigned dr_status_mirror; static unsigned dr_control_mirror; These are really never actually changed (their value is set from the DR values read from the inferior, but since we never change them, in practice, they never change). The fix is to use the values provided by debug_reg_state, and to eliminate the two dr_[...] globals. gdb/gdbserver/ChangeLog: * win32-i386-low.c (dr_status_mirror, dr_control_mirror): Delete. (i386_dr_low_get_control, i386_dr_low_get_status): Use dr_status_mirror and dr_control_mirror from debug_reg_state. (i386_dr_low_get_status): Use debug_reg_state.dr_status_mirror (i386_initial_stuff): Remove use of deleted globals. (i386_get_thread_context, i386_set_thread_context, i386_thread_added): Use dr_status_mirror and dr_control_mirror from debug_reg_state.
