[PATCH] D149800: [WIP][PGO] Add ability to mark cold functions as optsize/minsize/optnone

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin added a comment.

high level question, why not have it as a pass that runs after profiles (of 
whatever kind - instrumented or sample-based) are ingested. The pass would 
attribute functions as described.

(Nitpicking just on the invariant part) Not sure if that's always the 
invariant, because we could be inlining a call site in a SCC where both caller 
and callee are in that same SCC.

Worth maybe spelling that out in the patch description - i.e. why not go the 
D91567  route again, makes it easier to 
understand later.

This revision is now accepted and ready to land.

lgtm. Like @aeubanks was saying, let's just give a bit of time (1 month or so?) 
between when this lands and until we clean up the "mandatory" notion from the 
advisor, just to make sure nothing breaks/regresses.

IIRC we had at a point a mandatory , whole-module pass. The idea wast that 
let's not have N inliners, and that AlwaysInliner had some limitations, and for 
similar reasons @aemerson  pointed out, it'd make sense to first perform the 
mandatory inlines (D91567 ). In D94825 
 we went away from that. I don't remember why. 
@aeubanks? (it's referencing a patch you started)

LGTM, but I'd wait for Johannes to review it, too (because of 
e67f6477fd1ed29acbeddf8482c25d8db826912f 
. I for 
one don't quite follow the reasoning there wrt adding the `else`)

Right - they are different, there's a update_mir_test_checks and also an 
update_mca_test_checks; basically agreeing that, indeed, after patching _cc and 
_analysis (and update_test_checks), the remaining don't need patching.

Yup, checked that and the mir one. The latter seems to be implementing its own 
"add_checks", so would leave it as-is (plus, I'm guessing, by their nature, mir 
tests wouldn't get into this type of scenario anyway, IIUC).

How come the old error checking in CodeGenModule wasn't tripped before?

did git clang-format, and since that had to re-sort the includes due to my 
change, it affected incorrectly placed lines.

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin added a comment.

As this is a follow-up of a refactoring, I assume I can just land it (short of 
file header comments, there was nothing really this patch did more 
intelligently)

ah - `clang-format` handled the moved file as a new file; but I'd say let's let 
it make these changes, they are goodness anyway (and small)

This wraps up from D119053 . The 2 headers 
are moved as described,
fixed file headers and include guards, updated all files where the old
paths were detected (simple grep through the repo), and `clang-format`-ed it 
all.

[PATCH] D115393: [InstrProf][NFC] Refactor Profile kind into a bitset enum.

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin added inline comments.



Comment at: llvm/include/llvm/ProfileData/InstrProfReader.h:495
 
+  InstrProfKind getProfileKind() const override {
+InstrProfKind ProfileKind = InstrProfKind::Unknown;

This looks a lot like line 290, can it be refactored (or am I missing 
something?)



Comment at: llvm/lib/ProfileData/InstrProfWriter.cpp:337
   uint64_t CSSummarySize = 0;
-  if (ProfileKind == PF_IRLevelWithCS) {
+  if (static_cast(ProfileKind & InstrProfKind::CS)) {
 CSSummaryOffset = OS.tell();

consider adding helper APIs for test/set?

Could this be applied by a pass, early on in 
PassBuilder::buildPerModuleDefaultPipeline, if we determine we're not in 
ThinLTO post link? That way it would be a frontend-independent solution.

Should we do this if !Changed? Actually, if this function did not change 
(`Changed` is per cgscc)

Done. The 'unattempted' case is really an assert, but got a test for the 
attempted but failed.

I think that would be tricky, because they should not actually happen - the way 
we determine whether a site is alwaysinlinable checks (but not thoroughly) for 
legality. Let me see if I can find a regression test. It may be we can 
synthesize such a case in IR only, though, so not much of a help for the 
frontend tests?

iiuc it's preferred we place file-local types inside an anonymous namespace. 

Looking now at the [[ 
https://llvm.org/docs/CodingStandards.html#anonymous-namespaces | style 
guideline ]], it touts their benefits but also says I should have only placed 
de decl there and the impl of those members out... but the members are quite 
trivial. Happy to move them out though.

This also removes the need to disable the mandatory inlining phase in
tests.

In a departure from the previous remark, we don't output a 'cost' in
this case, because there's no such thing. We just report that inlining
happened because of the attribute.

(Drive-by thought) - maybe this is because a bunch of analyses that are needed 
during function simplification aren't needed anymore after. We could quickly 
check by adding a pass at the end of all function simplification, module-wide, 
that clears all fct analyses, and see if the memory overhead is still there?

If that's the case, we could identify what's not needed after function 
simplification and scope it somehow in a less hacky way than my above 
suggestion.

[PATCH] D95849: [FileCheck] Default --allow-unused-prefixes to false

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin added a comment.

In D95849#2535939 , @jhenderson wrote:

Except for the tests under  llvm/test/Transforms/Attributor/, which D94744 
 explicitly opts into allowing unused prefixes 
(and which @jdoerfert described as intentionally so), the rest (~1300) were 
bugs: i.e. unintentionally unused prefixes.

Out of them, a small handful were spelling mistakes (identified as such during 
code review by their authors) and fixed rather than removed.

right - I kept going back and forth between letting advisors handle that - you 
could, for example, imagine one that handled recursion and tracked 
caller/callee to allow a max number of recursive inlinings. But also something

this is the recursion avoidance test. it's separate from mandatory - I suppose 
we can factor it upfront.

yes, they change the stats that this inline advisor is tracking (currently nr 
edges, nodes, stuff like that)

[PATCH] D94825: [NewPM]i[Inliner] Move the 'always inliner' case in the same CGSCC pass as 'regular' inliner

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin updated this revision to Diff 317085.
mtrofin added a comment.

patched tests other than Other/ ones.

We want to rationalize emitting remarks, see also D94334 
; I'd prefer first landing the always inlining 
refactoring, because that would impact the remarks refactoring more than 
vice-versa (I think).

Expanding from D94808  - we ensure the same 
InlineAdvisor is used by both
InlinerPass instances. The notion of mandatory inlining is moved into
the core InlineAdvisor: advisors anyway have to handle that case, so
this change also factors out that a bit better.

[PATCH] D94808: [NewPM][Inliner] Move mandatory inliner inside function simplification pipeline

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin added a comment.

I think InlineAdvisor::getAdvice needs to take a bool MandatoryOnly, which 
Inliner then passes. This allows us to then use the same advisor for both the 
always case and the policy-driven inliner instances, which allows that advisor 
to correctly book-keep any module wide state it may want to.




Comment at: llvm/include/llvm/Transforms/IPO/Inliner.h:111
+  std::unique_ptr OwnedAdvisor;
+  bool Mandatory;
 };

Nit: const bool



Comment at: llvm/lib/Transforms/IPO/Inliner.cpp:661
 FunctionAnalysisManager , Module ) {
+  if (Mandatory) {
+OwnedAdvisor = std::make_unique(FAM);

This should move to line 675: if we have installed an advisor, we use it, and 
the inliner pass passes to getAdvice() whether it only needs mandatory advice. 
All advisors need to support the mandatory case anyway.

 That's a good idea. Probably we'd need to also make sure that the unused 
 prefixes are all on RUN lines with --allow-unused-prefixes=true.

 I'm also not sure how lit.local.cfg interacts with the test prefix 
 updater: currently, the only cases where we bulk-want to allow unused 
 prefixes is the Attributor tests. If you were going to add the flag 
 explicitly, that'd also work. Or just the option to the update_test_prefix

There's an earlier comment in this patch about that, anchored to line 296 of 
common.py. IIUC, a developer: 1) updates their test by adding new RUN lines, 
maybe adding prefixes to existing RUN lines, 2) runs the appropriate 
update_xyz_checks.py. Then, indeed, they

update_test_prefix.py's role is temporary: once we flip FileCheck to disallow 
unused prefixes by default, we don't need to keep it around. At that point, it 
becomes important for the update__test_check scripts to warn.

 The warnings are correct, but their purpose is to inform. For example, 
 take check_attrs. The third and fourth opt run produce different function 
 attributes from those produced by the first two, so the function is 
 different insofar as update_test_prefix is concerned. The warnings are 
 there to indicate that the listed prefixes end up not being used. But, 
 that's 'by design' for the attributor tests, IIRC.

 If the warnings are noise for you, we could add a flag to quiet them down, 
 which you'd flip when regenerating attributor tests?

The warnings are correct, but their purpose is to inform. For example, take 
check_attrs. The third and fourth opt run produce different function attributes 
from those produced by the first two, so the function is different insofar as 
update_test_prefix is concerned. The warnings are there to indicate that the 
listed prefixes end up not being used. But, that's 'by design' for the 
attributor tests, IIRC.

If the warnings are noise for you, we could add a flag to quiet them down, 
which you'd flip when regenerating attributor tests?

We need to have the advisor module-wide, because its goal is to track 
module-wide stats, which we leverage in the ML advisor.

I don't remember there being a particular challenge with the advisor - it was 
more that there was the other value of having a more accurate 'view' of the 
overall shape of the functions, if we want to include more context in inlining 
decision making. My preference would be to have a robust solution that 
addresses both this and the previous problem.

So I make sure I understand it correctly: it sounds like in PR48734, the callee 
wasn't first optimized through the function simplification pipeline, is that 
correct?

Let's try the mandatory inliner in the same CGSCC - happy to do that. Is 
PR48734 an emergency (I can take a look at this tomorrow morning PST)

Would running the function simplification pipeline after the always inline pass 
address the issue?

+common.warn_on_failed_prefixes(func_dict)

pengfei wrote:
> Can we move these warn to common.py?
Come to think of it, maybe moving it to common.py was not quite ideal:
- once a warning is issued in the middle of the list of RUN lines, it'll just 
be re-issued next time around; we could warn and exit, but that'd be annoying 
if there's another failure later in the RUN list.
- if we do it at the end, we can additionally distinguish the case where a 
prefix has an empty dict of funcs associated with it -> and the warning would 
be "there are unused prefixes - please remove %s'. This is more discoverable 
than llvm-lit -a, and also than relying on the user knowing to run 
uplate_test_prefix.

I think that the benefits (discoverability, better, more concise warnings) make 
the extra 2-3 lines worth it; and we already have tests for these other tools - 
wdyt?

Oh true! we can just do the check in build_function_body_dictionary_for_triple 
at the end.

I'll leave the additional tests, though, more tests never hurt.

[PATCH] D91567: [llvm][inliner] Reuse the inliner pass to implement 'always inliner'

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin updated this revision to Diff 308422.
mtrofin added a comment.

Fixed the LTO case.

Also fixed the p46945 test, which, post - D90566 
, was passing without the need of a 
preliminary always-inlier pass.
The reason is that the order of the traversal of the functions in a SCC 
changed. The test requies that the 'alwaysinline'
function be processed first (to render it recursive and, thus, uninlinable).

Thanks for doing this! Really good to have this data.

There's that benefit to simplifying the module with the always inliner before 
doing inlining "in earnest" I was pointing earlier at: for the ML policies 
work, we plan on capturing (sub)graph information. Using the same SCC would not 
help because the "higher" (callers) parts of the graph would have these 
mandatory inlinings not completed yet, and thus offer a less accurate picture 
of the problem space.

Awesome! Thanks!

If the rest of the (now NFC) patch seems reasonable, I'll go through those 
pesky pass manager tests to finish it up.

You mean for the variant where we ran some of the function passes, or you'd try 
running all of them? Probably the latter would be quite interesting as a 'worst 
case'.

 In the NPM, we didn't run the AlwaysInliner until D86988 
 . See also the discussion there. The 
 normal inliner pass was, and still is, taking care of the mandatory 
 inlinings if it finds them. Of course, if we completely upfronted those 
 (which this patch can do), then the normal inliner wouldn't need to. I'm 
 not suggesting changing that - meaning, it's straightforward for the 
 normal inliner to take care of mandatory and policy-driven inlinings. The 
 idea, though, is that if we upfront the mandatory inlinings, the shape of 
 the call graph the inliner operates over is simpler and the effects of 
 inlining probably more easy to glean by the decision making policy. There 
 are trade-offs, though - we can increase that "ease of gleaning" by 
 performing more function simplification passes between the mandatory 
 inlinings and the full inliner.

There was already an AlwaysInliner for the NPM, just wasn't used. So D86966 
 hooked that up in the NPM, basically. The 
implementation of that AlwaysInliner is separate from the Inliner pass. See 
Transforms/IPO/AlwaysInliner.cpp lines 36 - 114, vs Inliner.cpp, from 687 
onwards.

Yup, see BackendUtil.cpp:634. Can't comment on the latter problem.

Right - my point was that we could more easily explore doing so by having this 
new AlwaysInliner separate. In this patch I included those additional passes 
because I thought they may be necessary or beneficial, but I can remove them as 
a first step if they are not necessary. @jdoerfert - should the Attributor be 
run post-always inlining, or is it fine to not be run?

In the ML-driven -Oz case, we saw some marginal improvement. I haven't in -O3 
cases using the "non-ml" inliner. I suspect that it helps in the ML policy case 
(both -Oz and -O3, on which we're currently working), because: 1) the current 
-Oz takes some global (module-wide) features, so probably simplifying out the 
trivial cases helps; and 2) we plan on taking into consideration regions of the 
call graph, and the intuition is that eliminating the trivial cases (mandatory 
cases) would rise the visibility (for a training algorithm) of the non-trivial 
cases.

It would, and what I'm proposing here is equivalent to that, but the proposal 
here helps with these other explorations, with (arguably) not much of a  
difference cost-wise in itself (meaning, of course, if we discover there's 
benefit in running those additional passes, we pay with compile time, but in of 
itself, factoring the always inliner in its own wrapper, or in the same wrapper 
as the inliner, doesn't really come at much of a cost).

Now, if we determine there is no value, we can bring it back easily - wdyt?

AlwaysInlinerLegacyPass does, yes. The NPM variant doesn't.

From what I can see, the legacy one was used only in the O0/O1 
 cases, see 
clang/lib/CodeGen/BackendUtil,cpp:643. The full inliner isn't.

New pass manager survived for quite a while with only one inlining pass, that 
included a mandatorily strong preference for inlining always-inline functions? 
But still missed some recursive cases. So D86988 
 made the always inliner run right next 
to/before the inliner in the NPM.

It doesn't quite change the order D86988  
introduced. Specifically, D86988  ran 
AlwaysInliner (a module pass) first, then let the Inliner and function 
optimizations happen.
This patch keeps the order between doing mandatory inlinings and inlinings. 
But, in addition, if in the future we want to also perform some of the function 
passes that happen in the inliner case, to help the full inliner, we can more 
easily do so.

In the NPM, we didn't run the AlwaysInliner until D86988 
. See also the discussion there. The normal 
inliner pass was, and still is, taking care of the mandatory inlinings if it 
finds them. Of course, if we completely upfronted those (which this patch can 
do), then the normal inliner wouldn't need to. I'm not suggesting changing that 
- meaning, it's straightforward for the normal inliner to take care of 
mandatory and policy-driven inlinings. The idea, though, is that if we upfront 
the mandatory inlinings, the shape of the call graph the inliner operates over 
is simpler and the effects of inlining probably more easy to glean by the 
decision making policy. There are trade-offs, though - we can increase that 
"ease of gleaning" by performing more function simplification passes between 
the mandatory inlinings and the full inliner.

[PATCH] D91567: [llvm][inliner] Reuse the inliner pass to implement 'always inliner'

[Mircea Trofin via Phabricator via cfe-commits]

mtrofin added a comment.

Please note: the patch isn't 100% ready, there are those tests that check how 
the pipeline is composed, which are unpleasant to fix, so I want to defer them 
to after we get agreement over the larger points this patch brings (i.e. 
pre-performing always inlinings, value in further exploring cleanups before 
full inlining, etc)

mtrofin requested review of this revision.

Enable performing mandatory inlinings upfront, by reusing the same logic
as the full inliner, instead of the AlwaysInliner. This has the
following benefits:

- reduce code duplication - one inliner codebase
- open the opportunity to help the full inliner by performing additional

function passes after the mandatory inlinings, but before th full
inliner. Performing the mandatory inlinings first simplifies the problem
the full inliner needs to solve: less call sites, more contextualization, and,
depending on the additional function optimization passes run between the
2 inliners, higher accuracy of cost models / decision policies.

Note that this patch does not yet enable much in terms of post-always
inline function optimization.

I haven't tried that yet. @RKSimon's case was that the folder was fixed, and 
we'd want to stop the bleeding there. Now, thinking more about it: because 
FileCheck won't accept more than one occurrence of --allow-unused-prefixes, if 
a directory has cases where we want to allow duplicates, we'd probably want 
lit.local.cfg to do 2 things:

- set --allow-unused-prefixes to false, to stop the bleeding - this would be 
removed when we switch defaults
- define a %UnusedPrefixesFileCheck (or better name) which is FileCheck with 
the flag set to true, which we'd then use where needed instead of FileCheck. 
This could stay like this even after we switch defaults.

I'm not very versed with lit.local.cfg - does the above capture what you 
imagined? (@RKSimon too)

FYI - I realize the change is enormous. I don't necessarily mean to land it 
as-is, we can chunk it by directories and iteratively update this as those land.

[PATCH] D90366: [ThinLTO] Strenghten the test for .llvmcmd embedding

This just means the arguments are captured in memory. Nothing else changes. The 
only penalty is that a char vector (the captured args) are carried around even 
if .llvmcmd wasn't generated.

We could maybe add a test that no explicit optin to emitting .llvmcmd => no 
section (briefly looked, doesn't seem to exist for either non- or thinlto)

mtrofin requested review of this revision.

Always populate the CodeGenOptions::CmdArgs - the overhead is likely
negligible in the grand schema of things, and it keeps the using code
simple.
