[LLVMdev] [MSan] false positive from Memory Sanitizer?
In the example below, the Memory Sanitizier (from clang 3.3) reports an error:
#include <math.h>
int main() {
double x;
(void) modf(0, &x);
if (x) { // Boom
return 1;
}
return 0;
}
I see that modf() is not implemented by compiler-rt. Is it possible
to make the Memory Sanitizer assume that all un-instrumented functions
initialize any pointers arguments?

[LLVMdev] [GSoC 2014] Using LLVM as a code-generation backend for Valgrind
Hi,
I've seen on the LLVM's Open Projet Page [1] an idea about using LLVM to
generate native code in Valgrind. For what I know, Valgrind uses libVEX
to translate native instructions into a bitcode, used to add the
instrumentation and then translated back to native code for execution.
Valgrind and LLVM are two tools that I use nearly every day. I'm also
very interested in code
