25 # This script launches HotSpot.
26 #
27 # If the first parameter is either "-gdb" or "-gud", HotSpot will be
28 # launched inside gdb. "-gud" means "open an Emacs window and run gdb
29 # inside Emacs".
30 #
31 # If the first parameter is "-dbx", HotSpot will be launched inside dbx.
32 #
33 # If the first parameter is "-valgrind", HotSpot will be launched
34 # inside Valgrind (http://valgrind.kde.org) using the Memcheck skin,
35 # and with memory leak detection enabled. This currently (2005jan19)
36 # requires at least Valgrind 2.3.0. -Xmx16m will also be passed as
37 # the first parameter to HotSpot, since lowering HotSpot's memory
38 # consumption makes execution inside of Valgrind *a lot* faster.
