Hi Hal, I was looking into why this fails with dragonegg, and noticed the
following: if I compile with GCC (-O0) then I get as output:

Okay, can you resummarize? Do you mean that?

[LLVMdev] [Shrink-Wrapping] Request For Benchmarking: X86 and AArch64
Hi,
Shrink-wrapping capabilities, i.e., better placement of prologue and epilogue sequences, landed in r236507 but are not yet enabled by default.
Since r236507 AArch64 is shrink-wrapping ready, meaning we can turn the pass on for this target.
I’ve done the same for X86 in r 238293.
Now, I need your help to test and benchmark how shrink-wrapping perform on those targets.
The goal is to decide

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi all,
I've started looking at the GlobalMerge pass, enabled by default on
ARM and AArch64. I think we should reconsider that, at least for
AArch64.
As is, the pass just merges all globals together, in groups of 4KB
(AArch64, 128B on ARM).
At the time it was enabled, the general thinking was "it's almost
free, it doesn't affect performance much, we might as well use it".

CFLAA
Hi David,
I am the one who's responsible for CFLAA's refactoring in the summer.
I've sent out another email on llvm-dev, and you can find more about my
work in my GSoC final report.
I think it is fantastic that you have done such an interesting work.
I'll definitely try to help getting the code reviewed and merged in the
current. After a quick glance at your patch, it seems

[LLVMdev] IR Passes and TargetTransformInfo: Straw Man
Andy and I briefly discussed this the other day, we have not yet got
chance to list a detailed pass order
for the pre- and post- IPO scalar optimizations.
This is wish-list in our mind:
pre-IPO: based on the ordering he propose, get rid of the inlining (or
just inline tiny func), get rid of
all loop xforms...
post-IPO: get rid of inlining, or maybe we still need it, only
