ahh, naming is hard. I was thinking of required to run. Yes, it could also be required pass which is misleading. I'll go with BeforePassIsNotSkippedFunc which is not ambiguous.

Thanks for sending this!
I think fs::real_path isn't a great precedent to be following here, but
that we can put the same functionality behind a slightly different API.

For dotest style tests, the debug format to test is chosen by the test driver. All the tests should run with any format, but sometimes there are bugs in one reader or another (or in one version of DWARF or another) so you can skip or xfail a test based on format. Sounds like this test should be skipped when the debug format is PDB, since it seems like either the PDB format doesn't express a way to find the actual size of the vla (or the current PDB reader doesn't process those records).

- You are using Vector Function ABI mangled names, which means you ware assuming to link agains libsleefgnuabi.so instead of libsleef.so. For this reason, I think it is worth to replace the -fveclib=SLEEF option with -fveclib=SLEEFGNUABI. This request applies to all places where you have used SLEEF.
Sorry but I wholeheartedly disagree with this idea.
For starters, saying -fveclib=SLEEFGNUABI is just ugly IMO.
Furthermore, I do not understand why this change is necessary. It provides nothing that the current naming convention doesn't already provide. So, really, it's a matter of personal preference.

The symptoms of a collision are just going to be you can’t debug the

be resolved on the next incremental build

Yea this approach is fine I guess, but I’m not really a fan of gigantic
headers, so if it’s possible to use runtime polymorphism that seems better
to me. Otoh, I’m not the maintainer of the itanium demangler, so feel free
to ignore :)
Yea, I agree it’s mostly bugfixes. My hypothesis is that bugfixes are, on
average, pretty small and isolated, so it shouldn’t be too hard to port one
between the two even if they evolve separately. I’m curious what Erik

The MIR-Canon changes I've got coming soon will test createVirtualRegister but not createGenericVirtualRegister. It should be good enough for now I think.
Mar 29 2018
Could this bit be in a subsequent patch?
Right now im not exactly sure what the right way to go about this is because you have a vreginfos but they are named in much the way physregs are named. The named physregs have the map in MIParser. Still thinking of the right way to do this.

Agree with Duncan, but the llvm ref states that this implicit conversion comes at a cost, and at some point in time, may be reverted to mean what standard iterators are. So, I'll leave it as-is to avoid any fix-ups required in future.

Sorry for the late comment but Triple::isArch64Bit() doesn't correspond to ELF64 or ELF32 on MIPS. In particular, the triple used for the
N32 ABI will return true for isArch64Bit() but this ABI uses ELF32 objects. If lld doesn't support the N32 ABI yet then the current code is
ok for the remaining two ABI's (O32 and N64).
Ah, interesting. So N32 is a 32-bit ABI on 64-bit MIPS just like x32 ABI is on x86-64. Do you know how to determine whether it is ELF32 or ELF64 for such triple?

Right, my idea was to make loop-rotation more generic, thus enabling it on more complicated loops. It has some interesting corner cases though: for instance you can end up with several nested loops after rotating a single loop, but that's details, which we'll figure out in the process:)

The renaming also makes the diff hard to read which I don't like either. I
will revert the renaming part.

To elaborate a bit here: what's happening is that the update the list sees
is that you added the list and some reviewers, rather than an initial email
that contains the patch and your description of it so that people can scan
and look at patches without needing to go to phabricator.
I wonder if that's the right long term solution?

Although I like the change, I proposed something similar in http://lists.llvm.org/pipermail/llvm-dev/2016-May/099752.html and it was rejected.
Yeah, i don't either.
At this point, why don't we just have it own the caching walker and see
what it breaks.
May 31 2016
I know some of the issues are more a matter of personal preference than there being one true way. I just felt I should point out how I feel about them before people start writing them down as the one true way in the coding conventions :) I will of course not block the patches if we end up with a different style here.

You should probably note somewhere that assume is, in fact, readnone, we
just don't model it that way right now because it hasn't been changed to
use a real control dependency instead of a fake memory one.
This seems strange to me. For example, it breaks the otherwise very convenient:

llvm-objdump wants to print the relocationOffset, so it calls RelocationRef::relocationOffset which calls ELFObjectFile::getRelocationOffset
I plan on adding this to sys::fs::file_status indeed, hopefully it is not too hard and this patch can wait for it.
This is copy-pasted-adapted from module pruning. I plan to refactor module pruning to use this at some point.
Mar 22 2016
Ah, this is why. LGTM.
We can make it conditional (with a clang flag?), but the desired behavior is to be able to decide on enabling/disabling the caching at link time, so any bitcode static archive distributed would need to have a hash embedded. The user friendly choice would be to enabled it by *default* when -flto=thing, and an explicit option to disable it.

I would really ask the reviewers then if they will have a time to take a look on current aarch64 patches.

I'm concerned that fixing up GlobalOpt::deleteIfDead isn't enough
to avoid affecting CodeGen. There are other places in the
pipeline that will check Value::use_empty and/or have logic like
(or use directly) Function::isDefTriviallyDead. I think it's
important that the call to GV.removeDeadConstantUsers() has the
same effect on use-lists whether or not there's any debug info.
Moreover, GlobalOpt::deleteIfDead should have the same effect on
the entire module (including use-lists) regardless of debug info.
