[PATCH] D82256: [analyzer] Enabling ctr in evalCall event

2020-06-21 Thread Artem Dergachev via Phabricator via cfe-commits
NoQ added a comment.

Hmm, given that you're using ARC, you're probably intending to turn the review 
title/summary into a commit message. Let's make it prettier then:

- Commit messages are typically written in imperative mood, eg. "Enabling" -> 
"Enable", "Adding"/"Added" -> "Add".
- Abbreviating "constructor" to "ctr" was really unnecessary :)




Comment at: clang/lib/StaticAnalyzer/Core/ExprEngineCallAndReturn.cpp:586
   ExplodedNodeSet dstCallEvaluated;
+  EvalCallOptions CallOpts;
   getCheckerManager().runCheckersForEvalCall(dstCallEvaluated, dstPreVisit,

Oh well! You probably still don't need a separate local variable, can you try 
`EvalCallOptions()` or even `{}`?

[PATCH] D81678: Introduce frozen attribute at call sites for stricter poison analysis

2020-06-21 Thread Johannes Doerfert via Phabricator via cfe-commits
jdoerfert requested changes to this revision.
jdoerfert added a comment.
This revision now requires changes to proceed.

First, apologies for being late, I didn't properly monitor the list recently.

---

This diff is impossible to review and later to understand.

I would ask you to split it, at least for review purposes, such that (1) lang 
ref changes, (2) code changes, (3) test changes are separate.
Please also upload it with a full diff (at least for (1) and (2)).

The revision title needs to be updated (maybe add `[LangRef]` or `[Attr]`), and 
the commit message needs more explanation of the reasons and semantics.

---

Lang Ref (https://reviews.llvm.org/differential/changeset/?ref=2023449 <- so 
people can find it)

I think the spelling is not in line with other attributes and needs to be 
changed.

I'm unsure if we want the name `frozen` as it is less helpful to anyone now 
familiar with the frozen instruction.
In a different thread we concluded that we need some sort of `nopoison` as an 
attribute to convey the behavior is UB if the value would be poison.
I would very much prefer a self explanatory spelling here, especially since 
`nopoison` will be derived from sources other than the frozen instruction.

In the lang ref this is listed with and shown as string attribute. It should be 
with the regular ones (as it is implemented as such). It is also not target 
specific.

---

All in all we need to open this up to more people and go over the lang ref 
changes again.

Oh sorry, I missed the comment of @guiand above.
I wanted to suggest making things simpler by having its memory representation 
always have well-defined bits if stored into memory.
But, if it is helpful for MSan's performance because it is well-defined in C, I 
think it is fine to not care about the paddings.
I suggest explicitly mentioning that we're not considering paddings of 
aggregates in the LangRef (at the definition of frozen value too if you want; 
actually I thought it was already described in the definition, but it didn't).

In the nonnull thread I was in favor of `nopoison` as well, but became to think 
that `nopoison` is a bit misleading in this patch because it doesn't talk about 
undef bit.
Personally I preferred `frozen` because whenever there is an ambiguity in its 
semantics, the precise definition can be made by simply updating the notion of 
a frozen value, but if a more intuitive spelling is consideration I'm open to 
any suggestions.

[PATCH] D69778: Make -fmodules-codegen and -fmodules-debuginfo work also with precompiled headers

2020-06-21 Thread Luboš Luňák via Phabricator via cfe-commits
llunak added a comment.

So what more needs to be done here to get this change accepted? It's already 
missed 10.0 and 11.1 is getting branched off in about 3 weeks.

- The change was already accepted once and the problem leading to its revert 
has already been fixed.
- It just enables for PCH something that's been enabled for modules for a long 
time (so whatever may be wrong with it will probably be wrong with modules as 
well).
- I've been using the feature for 8 months.
- There's no publicly reported problem with it (I know aganea reported them 
above, but they are private, so nobody can do anything about them).
- The feature is opt-in and disabled by default.

[PATCH] D80961: Ignore template instantiations if not in AsIs mode

2020-06-21 Thread Stephen Kelly via Phabricator via cfe-commits
steveire added a comment.

Here's another example where it is not appropriate to transform a template 
instantiation:

http://clang-developers.42468.n3.nabble.com/Questions-discussions-about-cast-types-in-clang-td4068626.html

"If we call foo, it can be a const_cast, but if we call foo, it 
has to be a reinterpret_cast. In a situation where the user is writing library 
code, it won't only be relevant to the current translation unit but also for 
future purposes. Therefore, I propose that we leave dependent type c-style 
casts as they are."

Just recording it as part of the motivation of this patch.

LOG: [Remarks] Add callsite locations to inline remarks

Summary:
Add call site location info into inline remarks so we can differentiate inline 
sites.
This can be useful for inliner tuning. We can also reconstruct full 
hierarchical inline
tree from parsing such remarks. The messege of inline remark is also tweaked so 
we can
differentiate SampleProfileLoader inline from CGSCC inline.

LOG: [clang][test][NFC] Also test for serialization in AST dump tests, part 2/n.

The outputs between the direct ast-dump test and the ast-dump test after
deserialization should match modulo a few differences.

For hand-written tests, strip the ""s and
the "imported"s with sed.

For tests generated with "make-ast-dump-check.sh", regenerate the
output.

Part 2/n.

LOG: [clang][Serialization] Fix the serialization of ConstantExpr.

The serialization of ConstantExpr has currently a number of problems:

- Some fields are just not serialized (ConstantExprBits.APValueKind and
  ConstantExprBits.IsImmediateInvocation).

- ASTStmtReader::VisitConstantExpr forgets to add the trailing APValue
  to the list of objects to be destroyed when the APValue needs cleanup.

While we are at it, bring the serialization of ConstantExpr more in-line
with what is done with the other expressions by doing the following NFCs:

- Get rid of ConstantExpr::DefaultInit. It is better to not initialize
  the fields of an empty ConstantExpr since this will allow msan to
  detect if a field was not deserialized.

- Move the initialization of the fields of ConstantExpr to the constructor;
  ConstantExpr::Create allocates the memory and ConstantExpr::ConstantExpr
  is responsible for the initialization.

Review after commit since this is a straightforward mechanical fix
similar to the other serialization fixes.

LOG: [clang][test][NFC] Also test for serialization in AST dump tests, part 3/n.

The outputs between the direct ast-dump test and the ast-dump test after
deserialization should match modulo a few differences.

For hand-written tests, strip the ""s and
the "imported"s with sed.

For tests generated with "make-ast-dump-check.sh", regenerate the output.

Part 3/n.

[clang] a45f713 - add option to instantiate templates already in the PCH

LOG: add option to instantiate templates already in the PCH

Add -fpch-instantiate-templates which makes template instantiations be
performed already in the PCH instead of it being done in every single
file that uses the PCH (but every single file will still do it as well
in order to handle its own instantiations). I can see 20-30% build
time saved with the few tests I've tried.

The change may reorder compiler output and also generated code, but
should be generally safe and produce functionally identical code.
There are some rare cases that do not compile with it,
such as test/PCH/pch-instantiate-templates-forward-decl.cpp. If
template instantiation bailed out instead of reporting the error,
these instantiations could even be postponed, which would make them
work.

Enable this by default for clang-cl. MSVC creates PCHs by compiling
them using an empty .cpp file, which means templates are instantiated
while building the PCH and so the .h needs to be self-contained,
making test/PCH/pch-instantiate-templates-forward-decl.cpp to fail
with MSVC anyway. So the option being enabled for clang-cl matches this.

[PATCH] D82279: Handle invalid types in the nullPointerConstant AST matcher

2020-06-21 Thread Aaron Ballman via Phabricator via cfe-commits
aaron.ballman created this revision.
aaron.ballman added reviewers: rsmith, steveire, klimek, gribozavr.

Currently, using the nullPointerConstant AST matcher can lead to assertions in 
situations where a node to be matched does not have a valid type associated 
with it, such as a ParenListExpr. This patch addresses that by saying such 
nodes cannot be a null pointer constant. This addresses PR46353.

I like the direction of this, thank you! LGTM with a small suggestion, but you 
should wait a few days in case one of the other reviewers has comments.




Comment at: clang-tools-extra/clang-tidy/ClangTidyCheck.h:31-32
+template  struct OptionEnumMapping {
+  // Must provide:
+  // static ArrayRef> getEnumMapping();
+};

Any reason not to do:
```
static ArrayRef> getEnumMapping() = delete;
```
so you get a nice error if you instantiate something without the required 
definition?

I may be misunderstanding the comment here. I can understand not wanting to 
generate fixits into the scratch buffer (that would not do good things), but I 
think we still want a warning were it not for the macro, right? Just verifying 
that this is not changing warning behaviors, only fix-it behaviors.

Wait! I know the solution! I will try it tomorrow.

While this test in ASTMatchers might continue to make sense, shouldn't there be 
a test in `clang/unittests/AST` for this API? `isNullPointerConstant` seems to 
be complicated. Does it have a unit test?

You're absolutely right, however right now this fix just marks it as being 
`InsideMacro`. The reason diagnostics aren't emitted is becuase somewhere in 
this checks life someone decided to not emit warnings for declarations with 
usages inside macros. If that behaviour is to be changed a separate patch would 
be required.

I need to read the c++ standard, never even realised you could delete static 
functions like that.

[clang] 42c176c - [X86] Add 'cooperlake' and 'tigerlake' to __builtin_cpu_is.

2020-06-21 Thread Craig Topper via cfe-commits

Author: Craig Topper
Date: 2020-06-21T13:03:18-07:00
New Revision: 42c176c32851833f32863412e74235f085adc801

URL: 
https://github.com/llvm/llvm-project/commit/42c176c32851833f32863412e74235f085adc801
DIFF: 
https://github.com/llvm/llvm-project/commit/42c176c32851833f32863412e74235f085adc801.diff

LOG: [X86] Add 'cooperlake' and 'tigerlake' to __builtin_cpu_is.

Cooperlake can be detect by compiler-rt now, but not libgcc yet.
Tigerlake can't be detected by either. Both names are accepted by
gcc. Hopefully the detection code will be in place soon.

[PATCH] D82259: Deprecate error prone temporary directory APIs

Comment at: clang/lib/Driver/ToolChains/Clang.cpp:3177
   llvm::sys::path::append(Result, "ModuleCache");
 }
 

This default path is not ideal for Linux.  On Linux, if we want to put this 
into the home directory, we should follow XDG and put this into the 
`~/.cache/org.llvm.clang/ModuleCache`, respecting the environment variable 
`XDG_CACHE_DIR`.

ajwock updated this revision to Diff 272330.
ajwock added a comment.

It seems one of the issues that my tests revealed was already remedied in very 
recent changes, causing my test to fail. I changed the test to reflect that 
while also taking steven's recommendations.

Yes of course all the previous behavior is in the `WriteOptRecordFields` lambda 
capture. This adds an entirely new macro table and leaves the existing one 
untouched.

There is never going to be none as there currently already is an enum-based 
option that uses this setup, but it would still be nice to have a guard for 
that. Getting on it...

Actually this does not need any changes, it will correctly report 0 if there 
are no value tables.
