Allocating shadow tables at the bottom of memory on Linux.
.... I am curious about what the best way would be to create a shadow table at a fixed address in low memory starting at 0x10000 and extending upwards. I am unclear about the correct approach from looking at the DataFlowSanitizer since getOrInsertGlobal seems to be used on a limited number of times in runModule primarily to allocate thread local storage and I am uncertain how the code ensures that the runtime metadata doesnt get overwritten by alloca calls for the stack. Thanks in advance, Carter. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/...
