[LLVMdev] embedding trace functions to generate variable values
...se use soft batons (-;
I'm wondering if there is feature already in LLVM or clang to embed
variable tracing instructions in the compiled output, so that on execution
of the program, a dump of various variables values over time is generated.
It's a little like the old unix program ctrace[1], but using LLVM, instead
of rewriting C !

Thanx in advance,

No, I don't believe there is a tool quite like that in LLVM. However, we
have a research prototype dynamic backwards slicing tool c...
