As Nuno mentioned we are targeting the proposal for next week. I will update 
the ticket with the Discourse link once it becomes available.

[PATCH] D137107: Allow MS extension: support of constexpr with __declspec(dllimport).

[Eli Friedman via Phabricator via cfe-commits]

efriedma added inline comments.



Comment at: clang/lib/CodeGen/CGExprConstant.cpp:1926
+DiagnosticsEngine &Diags = CGM.getContext().getDiagnostics();
+Diags.Report(diag::warn_for_global_ctor_for_dllimport) << D;
+return nullptr;

I think this will trigger in cases we don't actually want it to; we only want 
to warn when we actually generate a global constructor, not when we end up 
falling back to generated code within a function.  (For example, we sometimes 
constant-evaluate local variables.)

EmitCXXGlobalVarDeclInitFunc has special cases for CUDA, OpenMP, thread-local 
variables, the InitSeg attribute, and inline variables.

[Owen Pan via Phabricator via cfe-commits]

owenpan updated this revision to Diff 485210.
owenpan added a comment.

Cleaned up the unit tests a little bit:

- Made them a little more varied.
- Removed some overlapping test cases.
- Removed integer literal suffixes for JavaScript.
- Added an octal `BigInt` test case for JavaScript.

[PATCH] D140543: [clang-format] Add an option to format integer literal separators

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

This seems to break tests everywhere, eg 
http://45.33.8.238/linux/95289/step_7.txt

Please take a look and revert for now if it takes a while to fix.

I had run FormatTests on Windows and macOS without any problems and don't 
understand why the build bots failed. I will disable the `FixRanges` test as a 
workaround.

LOG: [clang-format] Disable FixRanges in IntegerLiteralSeparatorTest

The FixRanges unit test from 46c94e5067b5 breaks the build bots.
Disable it for now.

FWIW it also fails on Windows and macOS on my bots: 
http://45.33.8.238/macm1/51645/step_7.txt 
http://45.33.8.238/win/72399/step_7.txt

If the test is failing, why not revert the commit for now instead of disabling 
the test? That's what we usually do.
