[LLVMdev] Patch: Don't do unprofitable narrowing of loads.
Our backend only does 32 bit loads. I noticed some loads were narrowed
to 8 bits and then had to be reverted back to 32 bit loads. This patch
prevents the initial lowering. I've only tested this on my backend. Can
someone review and apply this or should I submit a bug?

[Polly] Reduced code analyzability moving from LLVM 3.9.0 to 5.0.1
...Recently I was looking at the potential of optimizing through Polly. The
code that I am trying to optimize [1] adjusts a picture's colors to get
an Instagram-like effect.
To improve code analyzability on LLVM 3.9.0, I made the following changes:
- Improve SCoP detection through -polly-process-unprofitable
- Enable outer loop vectorization through -polly-vectorizer=stripmine,
disabling timeouts with -polly-dependences-computeout=0
- Avoid sign extensions by replacing all 32-bit ints with longs, as
Polly seems to model using 64-bit loop counters
- Avoid interrupting control flow through -ffast-math an...

LoopStrengthReduce.cpp
Hi,
I am looking for a way to rewrite induction variables to use an addition
of -1 whenever possible (and not otherwise unprofitable). This is needed
to utilize hardware loop instructions, which are present on SystemZ
(branch on count). Later in the backend, an 'add -1; compare w/ 0; jne
0'-sequence can be replaced with a brct instruction.
I could not find any way in the LSR pass to generate a formula for this
(neit...
