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