Subject: Add workaround to fix Stop action with Netbeans.
X-Git-Tag: v0.1.0
X-Git-Url: https://gerrit.automotivelinux.org/gerrit/gitweb?p=src%2Fxds%2Fxds-gdb.git;a=commitdiff_plain;h=68f893390feb6d4f442add4ac4152c9cb1112019

Add workaround to fix Stop action with Netbeans.

Netbeans sends -gdb-exit command when user press stop button. But this command is not processed by remote gdb if debugged program is running. So send a SIGINT signal to interrupt program before sending/executing -gdb-exit command.
