Building/Running LLVM Tests with Sanitizers
...but I
can't seem to get the right incantation of building LLVM with msan.
Here's what I've been doing:
1) Build the toolchain in one build directory, including `compiler-rt`.
2) Build the toolchain again with the just built toolchain in step 1,
but this time with `-DLLVM_USE_SANITIZER=MemoryWithOrigins`.
I get some msan errors, but of this kind instead of the one I'm expecting:
====
$ ./unittests/XRay/XRayTests
==236769==WARNING: MemorySanitizer: use-of-uninitialized-value
#0 0x70eef8
(/usr/local/google/home/dberris/xray/llvm-project-build-msan/unittests/XRay/XRayTests+0x70eef8)

How is llvm-opt-fuzzer supposed to be built and used with a pass pipeline?
...of re-implementing loop-simplify yourself in your pass?
I hope somebody here can and is willing to help me.
Kind Regards

P.S.: While on my above "adventure" I noticed that building LLVM with
clang and -DLLVM_USE_SANITIZER="MemoryWithOrigins" fails to complete
because it apparently detects a bug in one of the build helper tools.

Building with LLVM_PARALLEL_XXX_JOBS
I had only a quick view on the blog-texts.
It might be that a CLANG generated with LTO/PGO speeds up the build.
Can you confirm this?
Can you confirm binutils-gold speed up the build?
Has LLVM an own linker?
Can be used? Speedup the build?
Yesterday night I loooked through available CMAKE/LLVM variables...
### GOLD
# CMAKE_LINKER:FILEPATH=/usr/bin/ld
