[LLVMdev] Switching the new block placement pass on by default for 3.1
...n't be too flaky.
2) The code has been checked in and reviewed previously.
3) It completes a significant missing feature in LLVM with builtin_expect.
4) It "fixes" some of the regressions introduced with the inlining work by
more effectively ensuring the loops are laid out correctly. (yacr2
specifically exhibited this problem)
5) I see more positive movement in performance than negative, but that may
be an artifact of the testing I've been doing.
I'm planning to check in a change to enable it by default later tonight
(PST) and hopefully allow nightly testers to run through it...

[RFC] Enable Partial Inliner by default
Hi Graham,
Thank you for offering help. I am trying to create a reproducer. The problem is that the crashes happen whilst LTO is used. One thing I am sure about IR is broken at compile time.
Thanks,
Evgeny

I think the execution-time performance regression is mainly because of the unexpected performance improvements from non-SCEV canonicalization as shown int eh following bug: http://llvm.org/bugs/show_bug.cgi?id=1715...

[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".

RFC: Switching to the new pass manager by default
Greetings everyone!
The new pass manager is getting extremely close to the point where I'm not
aware of any significant outstanding work needed, and I'd like to see what
else would be needed to enable it by default. Here are the current
functionality I'm aware of outstanding:
1) Does not do non-trivial loop unswitching. Majority of this is in
https://reviews.llvm.org/D34200 but will

[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

[LLVMdev] 2.2 Prerelease available for testing
LLVMers,
The 2.2 prerelease is now available for testing:
http://llvm.org/prereleases/2.2/
If anyone can help test this release, I ask that you do the following:
1) Build llvm and llvm-gcc (or use a binary). You may build release
(default) or debug. You may pick llvm-gcc-4.0, llvm-gcc-4.2, or both.
2) Run 'make check'.
3) In llvm-test, run 'make TEST=nightly report'.
4) When
