IR Pass Ordering Sensitivity
...way of determining pass dependencies so that I can encode them into the tuner?
The test program can be found here: https://gist.github.com/kavon/92d153cdd54ce9b77162af3af47d4c95

Any indispensable passes?
...ee the semantics?
Here's my workflow just in case:
*********************************************************************************
1. Compile the source code to unoptimized IRs:
clang -c -emit-llvm -O0 test.c -o test.bc
2. Run opt with a set of IR->IR passes, e.g.,
opt -simplifycfg -sroa -inferattrs -globalopt -instcombine -simplifycfg
-prune-eh -inline -tailcallelim -simplifycfg -loop-simplify -lcssa
-loop-rotate -licm -gvn -verify test.bc -o test.bc
3. Run llc with -O0:
llc -file-type=obj test.bc -o test.o
4. Last link all the object files:
clang -O0 test1.o test2.o -o test

Determine reason for failure at -O1
Hi Everyone,
We caught a report for a failed self test when using Clang 5.0 and 6.0
with -DDEBUG and -O1 (i.e., a "debug build"). The code is question is
located at https://github.com/weidai11/cryptopp/blob/master/cham-simd.cpp
. It is the SSSE3 code path for CHAM64.
Other optimizations levels are OK for Clang. GCC, ICC and MSVC are OK.
The code is valgrind, Sanitizer, Coverity and
