Does LLVM_SANITIZE still work?

[Jiahao Chen]

Hi all,

I tried dusting off a build with LLVM_SANITIZE=1 specified in Make.user, which builds LLVM with AddressSanitizer.

I got many build errors of the form

X86ShuffleDecode.cpp:(.text._ZN4llvm15DecodeVPERMMaskEjRNS_15SmallVectorImplIiEE+0x2c1): undefined reference to `__asan_report_load8'

which persist even after wiping deps/llvm-* and rebuilding, and also with llvm 3.5.1.

Just wondering if anyone has tried recently and can tell me what I'm missing.

Thanks,

It's probably bitrotted a bit. I was planning to do a sanitizer run next week and will fix this then if nobody else gets to it first.
