Re: [PATCH] D14919: Fix IssueHash generation

[Orbán György via cfe-commits]

I did not create a test checker for the NormalizeLine error in the patch.
Should I add a test checker for this? Do you have any suggestions
where to put it if required?

GetEnclosingDeclContextSignature already checks for nullptr, this
should have been done in the NormalizeLine function also, but in that
case it is not enough because the Lexer needs the LangOpts.

Re: [PATCH] D14286: ASTImporter: expressions, pt.1

[Serge Pavlov via cfe-commits]

sepavloff added a comment.

If you are going to make unit tests, consider alternative approach also. In 
repository `test-suite` the directory `SingleSource/UnitTests` contains runtime 
tests obtained from single file. You could modify Makefile that runs these 
tests in such a way that each test runs twice, one as now it runs and the other 
would run through the sequence `compile to ast` - `compile empty source with 
with ast-import`. Tests for missing nodes could be added into 
`SingleSource/UnitTests`, they would be substantially simpler that those using 
ASTMatchers. More importantly, such tests would make indeed exhaustive testing 
of importer.

What about `CK_Generic`? Also, if `CK_i486` can be used for the 486SX, we need 
to exclude it here too. It looks (from wikipedia) like all the "WinChip" 
flavours of 486 have an x87 unit, but it'd be nice if someone could confirm 
that. Maybe we should have separate `CPUKind`s for 486 SX versus 486 DX.

[PATCH] Don't crash when dumping objc_bridge_related attributes

[Joe Ranieri via cfe-commits]

Clang's AST dumping currently crashes when dumping objc_bridge_related
attributes where the class method and instance method fields are left
empty. The attached patch marks the two arguments as optional and
updates TableGen to understand the optional flag for identifier
attribute arguments when generating the dump function.

r254107 - [analyzer] Include block capture copy expressions in the CFG.

[Devin Coughlin via cfe-commits]

[analyzer] Include block capture copy expressions in the CFG.

This prevents spurious dead store warnings when a C++ lambda is casted to a 
block.

I've also added several tests documenting our still-incomplete support for 
lambda-to-block
casts.

Thank you for extracting this.

First, this function deserves a doc comment now; I would suggest:

  /// Dynamically round a pointer up to a multiple of the given alignment.

Also, this is now generically useful, so (1) please rename OverflowArgArea to 
something more generic, like Ptr, and (2) please use LLVM value names based on 
the name already in Ptr.  That is, instead of "overflow_arg_area.align", please 
use
  Ptr->getName () + ".aligned"

Finally, please look for the other places in this file that you could change to 
use this new function.  There's one in emitVoidPtrDirectVAArg, and there are 
several other in other targets.

Please sink OverflowArgArea into the if block, since you don't need it outside.

Re: [PATCH] D12466: Fix empty -L Path on OSX hosts

[Martell Malone via cfe-commits]

martell added a comment.

> Is this testable?


Seems to me the only way to add this as a test would be to add bad code to 
clang to purposely pass an empty LibPath argument.
This is probably something we do not want to do.

This is probably why Reid never asked me for one in the review.

[PATCH] D15005: Fix PR8170: Clang does not check constructor declaration that uses a template-id

[Faisal Vali via cfe-commits]

faisalv created this revision.
faisalv added a reviewer: rsmith.
faisalv added a subscriber: cfe-commits.

Clang currently does no real checking of the template argument list when a 
template-id is used to declare a constructor:

template struct X {
  X(); // Clang erroneously accepts this.
};

Both gcc and edg emit an error on the above code (though one could claim the 
spec temp.local p1 is perhaps not as explicit as it could be in this regard)

See: https://llvm.org/bugs/show_bug.cgi?id=8170

Re: [PATCH] D14982: ARM v8.1a adds Advanced SIMD instructions for Rounding Double Multiply Add/Subtract.

Do these get the right diagnostics when used on CPUs without the new feature? I 
can't see how __ARM_FEATURE_QRDMX gets wired through to arm_neon.h.

Hmm. I guess you need to sign up for the cast expression rather than for the 
binary operator expression. By the time you reach the assignment operator, the 
value before the cast is already removed from the environment.

r254083 - Stop using SFINAE to detect whether a derived-class override of Traverse* can

[Richard Smith via cfe-commits]

Author: rsmith
Date: Wed Nov 25 13:33:20 2015
New Revision: 254083

URL: http://llvm.org/viewvc/llvm-project?rev=254083=rev
Log:
Stop using SFINAE to detect whether a derived-class override of Traverse* can
take a queue; some supported versions of GCC believe that this substitution
failure is an error. Instead, use a partial specialization to detect the type
of a pointer to the corresponding member. This is less general, but good enough
for our uses.

We will still allow it in system headers, in macros from system headers, when
combined with an 'asm' label, and under the flag -Wno-register.

r254134 - [Diagnostics] Call setMapping on the correct diagnostic states in a few places. GetCurDiagState() was being used when it shouldn't be.

[Craig Topper via cfe-commits]

Date: Wed Nov 25 23:51:54 2015

Log:
[Diagnostics] Call setMapping on the correct diagnostic states in a few places. 
GetCurDiagState() was being used when it shouldn't be.

I spotted this by inspection in the for loop that wasn't using its iterator and 
was just acting on the current state repeatedly.

This appears to have been introduced as a copy and paste bug in r140763 over 4 
years ago.

I have no idea how to test this. I just went back to the original commit and 
tried to use the variables it was using before that.

Re: [PATCH] D15006: Driver: Better detection of mingw-gcc

[Martell Malone via cfe-commits]

martell updated this revision to Diff 41209.
martell added a comment.

Updated to reflect feedback

I'm not too sure what todo for testcases on this one because they already exist 
for the most part.
I ran the test suite and they all pass.

I would have to create a mingw32-gcc and {armv7|i686|x86_64}-w64-mingw32-gcc 
and chmod+x for the testcase.
Is that safe ?

r254067 - [MSVC] 'property' with an empty array in array subscript expression.

[Alexey Bataev via cfe-commits]

Author: abataev

New Revision: 254067

Log:
[MSVC] 'property' with an empty array in array subscript expression.
MSVC supports 'property' attribute and allows to apply it to the declaration of 
an empty array in a class or structure definition.
For example:
```
__declspec(property(get=GetX, put=PutX)) int x[];
```
The above statement indicates that x[] can be used with one or more array 
indices. In this case, i=p->x[a][b] will be turned into i=p->GetX(a, b), and 
p->x[a][b] = i will be turned into p->PutX(a, b, i);

[PATCH] D14982: ARM v8.1a adds Advanced SIMD instructions for Rounding Double Multiply Add/Subtract.

[Alexandros Lamprineas via cfe-commits]

labrinea created this revision.
labrinea added reviewers: jmolloy, rengolin, cfe-commits.
Herald added subscribers: rengolin, aemerson.

The following instructions are added to AArch32 instruction set:
  - VQRDMLAH: Vector Saturating Rounding Doubling Multiply Accumulate Retu   
ing High Half
  - VQRDMLSH: Vector Saturating Rounding Doubling Multiply Subtract Returning 
High Half

The following instructions are added to AArch64 instruction set:
  - SQRDMLAH: Signed Saturating Rounding Doubling Multiply Accumulate Returning 
High Half
  - SQRDMLSH: Signed Saturating Rounding Doubling Multiply Subtract Returning 
High Half

This patch adds intrinsic and ACLE macro support for these instructions, as 
well as corresponding tests.

Or even better, just use the portable memset(, 0, sizeof(mb)).

Sorry for the delay, I was sick and didn't read mail.

Looks good with a nit. Thanks for the fix!

Re: [PATCH] D15006: Driver: Better detection of mingw-gcc

[Yaron Keren via cfe-commits]

yaron.keren added a comment.

This always searches for something-gcc and then discards the result if sysroot 
was provided, which is a waste.
Move the searching to a helper function and then it can be done only if sysroot 
was not provided, as it is now.

The break is needed to avoid looking for mingw32-gcc after 
x86_64-w64-mingw32-gcc was already found. It's a wasted search.
