# 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. |
