llvm-mc-[dis]assemble-fuzzer status?
Hi, As a part of a recent move of libFuzzer from LLVM to compiler-rt I am looking into updating the build code for the libraries which use libFuzzer. I have tried to compile llvm-mc-assemble-fuzzer, and llvm-mc-disassemble-fuzzer, and I couldn’t build either of those. For the first one, the reason is that it refers to a nonexistent enum, and for the second one I believe the reason is that it

moving libfuzzer to compiler-rt?
+ Chandler, Danny, We are considering to move the libFuzzer code from llvm to compiler-rt, and that implies a license change. Will it be sufficient to do the following? * e-mail to all contributors (a short list, below) asking for their consent * remove any code for which we did not get consent in, say, 1 week. (BTW, this list is actually much shorter, I recognize many of these as belonging

Thank you for your reply! I have two additional questions: 1) Why is it ripping the code out if compiler-rt is still part of LLVM? 2) Does it mean

LibFuzzer syntax sugar flag
Hi All, Recently we have introduced a short syntactic sugar flag for compiling a file with libfuzzer: one just needs to add “-fsanitize=fuzzer” to the command line, and the driver would specify coverage flags and link with libfuzzer automatically. I wanted to ask whether it would make more sense to rename the flag to “-ffuzzer”, as it’s not a sanitizer, and it has a much heavier effect. Thanks,

LibFuzzer syntax sugar flag
I think libfuzzer deserves its own flag. I view fuzzing as a smarter testing technology while sanitizers are associated with inserting additional checks into the program. The different linking behavior is another major difference.

One question: will it make sense to *copy* the code to the new location, work on it, then delete the code from the old location, instead of doing a move in a single commit? I don't expect any dramatic changes

Building LLVM's fuzzers
(kcc, george: sorry for the re-send, the first was from a non-list email address) My configuration for building the fuzzers in the LLVM tree doesn't seem to work any more (possibly as of moving libFuzzer to compiler-rt, but there have been a few other changes in the last week or so that may be related). I'm building with a fresh top-of-tree clang and setting -DLLVM_USE_SANITIZER=Address
