From e9110f4f31d4034296f20fab2bbad0f63a4b312e Mon Sep 17 00:00:00 2001 From: Fernando Nasser Date: Thu, 12 Oct 2000 22:56:31 +0000 Subject: [PATCH] 2000-10-11 Fernando Nasser From Grant Edwards This keeps the GUI alive while running an RDI target and lets the STOP button be used to stop the target. * remote-rdi.c (arm_rdi_stop): New function. Implements target_stop. (init_rdi_ops): Set to_stop target vector entry to the above. * rdi-share/ardi.c (stop_request): New variable. Tells when a stop has been requested. (angel_RDI_stop_request): New function. Registers that a stop has been requested. (angel_RDI_ExecuteOrStep): Add call to ui_loop_hook() in loop that waits while target is executing. Initialize and reset stop_request. * rdi-share/ardi.h: Add declaration of angel_RDI_stop_request(). --- gdb/ChangeLog | 15 +++++++++++++++ gdb/rdi-share/ardi.c | 18 ++++++++++++++++-- gdb/rdi-share/ardi.h | 2 ++ gdb/remote-rdi.c | 8 ++++++++ 4 files changed, 41 insertions(+), 2 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 484cf0e825..e0a7ba2ecb 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,18 @@ +2000-10-11 Fernando Nasser + + From Grant Edwards + This keeps the GUI alive while running an RDI target and lets the + STOP button be used to stop the target. + * remote-rdi.c (arm_rdi_stop): New function.
