[PATCH] D27157: IRGen: Remove all uses of CreateDefaultAlignedLoad.

2016-11-27 Thread John McCall via Phabricator via cfe-commits

rjmccall added a comment.

Thanks for doing this!  A couple minor questions / comments.




Comment at: clang/lib/CodeGen/CGBuiltin.cpp:2195
 LoadInst *Load =
-Builder.CreateDefaultAlignedLoad(IntToPtr, /*isVolatile=*/true);
+Builder.CreateAlignedLoad(IntTy, IntToPtr, CharUnits::fromQuantity(4));
+Load->setVolatile(true);

Why 4?



Comment at: clang/lib/CodeGen/TargetInfo.cpp:3560
+TyHi, CGF.Builder.CreateBitCast(RegHiAddr, PTyHi),
+CharUnits::fromQuantity(getDataLayout().getABITypeAlignment(TyHi)));
 CharUnits Offset = CharUnits::fromQuantity(

Please leave a comment mentioning that this is probably pessimistic.

[PATCH] D26904: [astimporter] Support importing CXXDependentScopeMemberExpr and FunctionTemplateDecl

2016-11-27 Thread Kareem Khazem via Phabricator via cfe-commits

khazem updated this revision to Diff 79371.
khazem added a comment.

Thanks for the comments, Aleksei!

I've merged some aspects of the code you pointed me to, although I had to 
change some of it because some of the function calls have changed since 2015. 
In particular, I'm checking for already-imported functions, and adding the decl 
to the imported map.

I'm not sure how to proceed with tests. I was looking at 
test/ASTMerge/class-template-partial-spec.cpp, would it be something like this?

But I'm not sure what error I should throw if we have already imported the 
function, there is no appropriate error in 
include/clang/Basic/DiagnosticASTKinds.td. Should I define a new error, e.g. 
"function %0 defined in multiple translation units"?

[PATCH] D27153: [libc++] Make __num_get_float hidden

2016-11-27 Thread Shoaib Meenai via Phabricator via cfe-commits

smeenai added a comment.

I'm having some second thoughts about this. Visibility for template functions 
makes my head spin :/ Is there a general policy we've been following for these? 
I didn't find much just scanning through other definitions.

It's an internal function and shouldn't be exported. It's also a source
of discrepancy in the published ABI list; these symbols aren't exported
for me on CentOS 7 or Ubuntu 16.04, leading to spurious check-cxx-abilist
failures.

[PATCH] D26934: [libc++] Add _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS

2016-11-27 Thread Shoaib Meenai via Phabricator via cfe-commits

smeenai added inline comments.



Comment at: include/__config:513-516
 #if defined(_LIBCPP_DISABLE_DLL_IMPORT_EXPORT)
+// this can be removed once any existing users have switched to the new macro
+# error "Use _LIBCPP_DISABLE_VISIBILITY_ANNOTATIONS instead of 
_LIBCPP_DISABLE_DLL_IMPORT_EXPORT"
+#endif

I'd like to remove this before the 4.0 release, if that's all right with you. I 
don't think there would be many users of the existing macro, and I'd prefer it 
to not make its way to a release.

Hey, for what it's worth when skipping the free at this line: 
https://github.com/llvm-mirror/clang/blob/master/bindings/python/clang/cindex.py#L181
 the issues are gone, I haven't investigated the reason why.

r287999 - Adjust type-trait evaluation to properly handle Using(Shadow)Decls

2016-11-27 Thread Hal Finkel via cfe-commits

Author: hfinkel
Date: Sun Nov 27 10:26:14 2016
New Revision: 287999

URL: http://llvm.org/viewvc/llvm-project?rev=287999&view=rev
Log:
Adjust type-trait evaluation to properly handle Using(Shadow)Decls

Since r274049, for an inheriting constructor declaration, the name of the using
declaration (and using shadow declaration comes from the using declaration) is
the name of a derived class, not the base class (line 8225-8232 of
lib/Sema/SemaDeclCXX.cpp in https://reviews.llvm.org/rL274049). Because of
this, name-based lookup performed inside Sema::LookupConstructors returns not
only CXXConstructorDecls but also Using(Shadow)Decls, which results assertion
failure reported in PR29087.

Patch by Taewook Oh, thanks!

[PATCH] D26082: Support for Python 3 in libclang python bindings

2016-11-27 Thread Jonathan B Coe via Phabricator via cfe-commits

jbcoe added a comment.

Thanks Mathieu.

Tests ran without issues when I submitted my patch but I tested on macOS.

I'll have a look into this and see if I can reproduce the problem.
