X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=526b1b7ec8da5b770a345a2ea1b3f7471a533d44;p=gem5.git

misc: Adds a warning in case gdb is attached multiple times
Instead of scheduling another event, this patch adds a warning in case gdb
is attached multiple times and the first attachement event has not been
processed yet.
