Building LLVM's fuzzers
...ilding 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 and -DLLVM_USE_SANITIZE_COVERAGE=On, which
was working before:
% cmake -GNinja \
-DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=On \
-DLLVM_ENABLE_WERROR=On \
-DLLVM_USE_SANITIZER=Address -DLLVM_USE_SANITIZE_COVERAGE=On \
-DCMAKE_C_COMPILER=$HOME/llvm-lkgc/bin/clang \

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
