First goal: eliminate false + positives when gc is accessing uninitialized parts of the stack. + + * configure (valgrind): New variable. Defaults to false (do not + build valgrind support). New check for whether the valgrind API + is actually avilable if --valgrind is selected. + (HAVE_VALGRIND): Conditionally added to config.h. + + * gc.c: Conditionally include valgrind memcheck.h header. + (mark_mem_region): After pulling out a value from the stack, + mark that copy as defined memory using VALGRIND_MAKE_MEM_DEFINED. + (mark): Removed check for a registered root variable pointer + being null; this cannot happen, unless someone registers a + null pointer, or the stack is trashed. The comment about a + possible null was misleading. + 2009-11-24 Kaz Kylheku <kkylheku@gmail.com> Fix uninitialized memory locations. |
