Ping~ It looks to me there's no concern about this solution in the RFC 
. I 
think we can move forward to land it.

BTW, maybe @aaron.ballman knows why we don't support such syntax in C++.

Herald added subscribers: cfe-commits, wangpc, eopXD, MaskRay.
Herald added a project: clang.

This patch handles vector type and tuple type arguments
calling convention. Vector type arguments can be passed
directly by register or by reference, however tuple type
arguments are split into multiple vector type arguments,
all of these arguments should be either passed by references
or passed by registers.

LOG: [Driver][DXC] Remove a bunch of options from DXC

Remove DXCOption from a whole bunch of options that we probably won't
support in the DXC driver. The initial clang-dxc support just made
everything that was a "CoreOption" available, regardless of whether it
made sense. Here I don't remove all of them, but this makes a dent on
making the list a bit more sensible. We can easily add or remove more
if they make sense later.

need a FIXME. The FIXME should instead be added to the comment above the

Thank you.  I was wondering which group options are required here.

I see.  Changed.

Yes.

A reliable source about double colon operator cannot resolve function with 
parentheses in C++ is the best I expect, however I haven't find one so far.
Maybe a short description about the phenomenon on GCC/Clang is better than just 
giving error message. I don't have strong request for this.

[PATCH] D158047: [clang][ASTImporter] Add import of 'BitIntType'

[Timo Stripf via Phabricator via cfe-commits]

strimo378 added a comment.

I think the ASTImporter class has in general a completion problem. What do you 
think about rewriting it that any missing Visit* function for Type, Decl and 
Stmt produces an compiler error?

Since we also have VLST for rvv now, it is not clear to keep using 
`isVLSTBuiltinType`, so I added prefix SVE to it.

[PATCH] D157297: [clang] Fixes compile error that double colon operator cannot resolve macro with parentheses.

[Phoebe Wang via Phabricator via cfe-commits]

pengfei added a comment.

I'd prefer macro to duplicated definitions. We have such precedents, e.g., 
https://github.com/llvm/llvm-project/blob/main/clang/lib/Headers/xmmintrin.h#L2994
Besides, you should update the summary as well.

The spec does not mention it is incompatible with Zca. I think I need to enable 
c.push/c.popchk for Zca.

[PATCH] D158006: [Clang][WIP]Experimental implementation of data member packs in dependent context.

[Denis Nikitin via Phabricator via cfe-commits]

denik added inline comments.

+if (Field->getDeclName() == NameInfo.getName()) {
+  if (const PackExpansionType *PET =
+  dyn_cast(Field->getType())) {
+isMemberPack = true;

if (isa(Field->getType())) { ...



Comment at: clang/lib/Sema/SemaExprMember.cpp:1018
   if (R.empty()) {
+// The member is expaned from member pack if its name has `@` in it. In 
this
+// case a failed name lookup is not an error, but represents it's at the 
end

expanded



Comment at: clang/lib/Sema/SemaTemplateInstantiate.cpp:3289
+  // Rename the expanded fields to avoid ambiguous names in
+  // name lookup. The renamed fields need to be invisible to users so 
an
+  // `@` is added to the name.

nit: Maybe `inaccessible by`?



Comment at: clang/lib/Sema/TreeTransform.h:4177
+   "trying to expand non-pack member access");
+std::string UnExpanedNameStr =
+MemberExpr->getMemberNameInfo().getName().getAsString();

Expanded



Comment at: clang/lib/Sema/TreeTransform.h:4198-4199
+  MemberExpr->getMemberNameInfo().getInfo());
+  TemplateArgumentListInfo TemplateArgs = TemplateArgumentListInfo();
+  MemberExpr->copyTemplateArgumentsInto(TemplateArgs);
+  auto *ExpandedMemberExpr = CXXDependentScopeMemberExpr::Create(

Why is this in a loop?



Comment at: clang/lib/Sema/TreeTransform.h:4208
+
+  Sema::ArgumentPackSubstitutionIndexRAII SubstIndex(getSema(), Arg);
+  ExprResult Out = getDerived().TransformExpr(ExpandedMemberExpr);

Can we add a check that Arg never exceeds the number of arguments in the full 
expansion (is it Expansion->getNumExpansions()?)



Comment at: clang/test/CodeGenCXX/data_member_packs.cpp:76
+  // CHECK: double @_Z3sumIJilfdEEDaDpT_(i32 noundef %ts, i64 noundef %ts1, 
float noundef %ts3, double noundef %ts5)
+  S4{}.sum_pack(s7);
+  return 0;

This is a good test case!
I would also add a test for the partial expansion of the member pack. And also 
checking the right order of the fields. Something like:
```
template constexpr auto foo(T t) { return t; }
template constexpr auto foo(T t, Ts ... ts) { 
return t + 2 * foo(ts...); }

S1 s = {1,2,3};
static_assert(foo(s.ts...) == 17);
```

Can you call this `rs1val` instead of `rs1` since $rs1 is part of the ins.

[clang] cb6fe61 - [Driver][DXC] Handle -Fo and -Fc flags

[Justin Bogner via cfe-commits]

Author: Justin Bogner
Date: 2023-08-15T16:37:17-07:00
New Revision: cb6fe61be3dee67bb8b080c73dd2c48f2d0ce2c7

URL: 
https://github.com/llvm/llvm-project/commit/cb6fe61be3dee67bb8b080c73dd2c48f2d0ce2c7

LOG: [Driver][DXC] Handle -Fo and -Fc flags

This splits the backend and assemble actions for HLSL inputs and
handles the options in GetNamedOutputPath instead of aliasing `-o`.
This also moves how we default to emitting asm to stdout, since doing
this in the HLSL toolchain rather than the driver pollutes how the
clang driver works as well.

When both options are specified we disable collapsing the assemble
action and attempt to generate both outputs. Note that while this
handles the driver aspects, we can't actually run in that mode for now
since -cc1as doesn't understand DXIL as an input yet.

Remove DXCOption from a whole bunch of options that we probably won't
support in the DXC driver. The initial clang-dxc support just made
everything that was a "CoreOption" available, regardless of whether it
made sense. Here I don't remove all of them, but this makes a dent on
making the list a bit more sensible. We can easily add or remove more
if they make sense later.

[PATCH] D150262: Disable sanitizer's on ifunc resolvers.

[Farzon Lotfi via Phabricator via cfe-commits]

farzon added a comment.

I feel like this change will break our use case and do so in a nontransparent 
way. We want to be able to use sanitizers even if IFUNC indirection is defined.

So if the compiler toolchain is now going to disable santizer instrumentation 
overriding the preferences of the person building the software then that is 
going to regress https://bugs.chromium.org/p/chromium/issues/detail?id=1454613 
again and make it so we can't fuzz on arm64.

Instead can we not just fail the build? That way the CI will be the enforcer 
and the next developer that comes along will have to create a happy path to 
support sanitizer builds.

[PATCH] D157452: [RFC][Clang][Codegen] `std::type_info` needs special care with explicit address spaces

[Alex Voicu via Phabricator via cfe-commits]

AlexVlx updated this revision to Diff 550516.
AlexVlx added a comment.

Remove unneeded cast, the dynamic case already emitted a generic pointer to 
`typeinfo`

[PATCH] D157445: [CodeGen][UBSan] Add support for handling attributed functions in getUBSanFunctionTypeHash.

[Fangrui Song via Phabricator via cfe-commits]

MaskRay accepted this revision.
MaskRay added inline comments.



Comment at: clang/test/CodeGen/ubsan-function-attributed.c:3
+
+// CHECK: .long248076293
+void __attribute__((ms_abi)) f(void) {}

It's useful to add `// CHECK-LABEL: f:` interleaving with `.long xxx`. The 
FileCheck error will be better when the hash changes.

 Ideally, this method requires a FrontendAction with `hasCodeCompletionSupport` 
returning `true`.  The reason I chose  `SyntaxOnlyAction` are 1. the old code 
used it 2.  `SyntaxOnlyAction::hasCodeCompletionSupport` returns `true`.  
Certainly, right now `SyntaxOnlyAction` does not prevent its subclasses from 
overriding this method.

+/// Code completion at a top level in a REPL session.

Nice. This one sounds better indeed.

[PATCH] D157445: [CodeGen][UBSan] Add support for handling attributed functions in getUBSanFunctionTypeHash.

[Yeoul Na via Phabricator via cfe-commits]

rapidsna accepted this revision.
rapidsna added a comment.
This revision is now accepted and ready to land.

The changes look good to me. Ideally, we could add tests with multiple 
attributes and possibly with other sugar types.

[PATCH] D158021: [clang][modules] Mark builtin header 'inttypes.h' for modules

[Ben Langmuir via Phabricator via cfe-commits]

benlangmuir updated this revision to Diff 550474.
benlangmuir added a reviewer: vsapsai.
benlangmuir added a comment.

Add missing test updates: tests using the `Inputs/System/usr/include` should be 
using `-internal-isystem` to get the correct search path order with respect to 
the resource dir. The tests that were previously using `-isystem` were only 
working before because the other headers wrap their `#include_next` in 
`__has_include_next`, which was causing them to silently be missing these 
headers. With inttypes.h the include_next is unguarded, which revealed the 
issue.  Note: even if we someday add the has_include_next guard to inttypes.h 
the test change is still correct.

[PATCH] D155064: [clang][SemaCXX] Diagnose tautological uses of consteval if and is_constant_evaluated

[Takuya Shimizu via Phabricator via cfe-commits]

hazohelet added a comment.

Thanks for the feedback.




Comment at: clang/test/SemaCXX/warn-constant-evaluated-constexpr.cpp:38
 constexpr int fn5() {
-  if constexpr (__builtin_is_constant_evaluated()) // expected-warning 
{{'__builtin_is_constant_evaluated' will always evaluate to 'true' in a 
manifestly constant-evaluated expression}}

{{'__builtin_is_constant_evaluated' will always evaluate to true in this 
context}}
 return 0;

cjdb wrote:

I think it's reasonable to show fix-it hint to remove `constexpr` here.
For that we need to store the source range of `constexpr` in evaluation context 
record if it's constexpr-if condition.



Comment at: clang/test/SemaCXX/warn-tautological-meta-constant.cpp:18
+  } else {
+if constexpr (std::is_constant_evaluated()) { // expected-warning {{always 
evaluate to true}}

I agree that the current wording (`... will always evaluate to true in this 
context`) is not great, but I'm not sure how to improve it because the reason 
to see this diagnostic would mostly be a misunderstanding of the C++ const 
semantics.
At least, if the appearance of `is_constant_evaluated` is in the condition of 
constexpr-if, probably we can say they should remove `constexpr`.

[PATCH] D158006: [Clang][WIP]Experimental implementation of data member packs in dependent context.

[Christopher Di Bella via Phabricator via cfe-commits]

cjdb added inline comments.



Comment at: clang/lib/Sema/SemaTemplateInstantiate.cpp:3292
+  std::string NewFieldName =
+  PackedField->getName().str() + "@" + std::to_string(Arg);
+  PackedField->setDeclName((NewFieldName));

Does LLVM have some form of `absl::StrCat` that we can use instead of 
`operator+`?



Comment at: clang/lib/Sema/TreeTransform.h:4191-4218
+  // Transform unexpanded field name and create a new member 
expression.
+  DeclarationName ExpandedName = (
+  UnExpanedNameStr + "@" + std::to_string(Arg));
+  // Construct name info with new name and keep other members the same.
+  DeclarationNameInfo ExpandedNameInfo = DeclarationNameInfo(
+  ExpandedName, MemberExpr->getMemberNameInfo().getLoc(),
+  MemberExpr->getMemberNameInfo().getInfo());

It may be worth putting this into its own named function to help with 
readability.



Comment at: clang/test/CodeGenCXX/data_member_packs.cpp:73
+  // CHECK: i32 @_Z3sumIJiiEEDaDpT_(i32 noundef %ts, i32 noundef %ts1)
+  sum_pack2(s6);
+  // Check instantiation of sum(int, long, float, double)

This needs to be passed to one of the sum functions and checked that it's 
generating the correct code.

[PATCH] D157994: [OpenMP] Migrate dispatch related utility functions from Clang codegen to OMPIRBuilder

This revision is now accepted and ready to land.

LG, but do not remove the Attribute from our set, add it to the tests. The 
functions are nounwind.

If we're avoiding the expense here when we're not emitting incremental 
extensions, this seems fine to me.

D157379  seems to resolve the concern but 
indeed we can wait a little longer.

Moved the tests into machine-function-splitter.ll. Either this CL or D157563 
can be submitted first, and the other will rebase on top of that.

[PATCH] D151567: [LLVM][Support] Report EISDIR when opening a directory on AIX

[Fangrui Song via Phabricator via cfe-commits]

MaskRay requested changes to this revision.
MaskRay added a comment.
This revision now requires changes to proceed.

Thanks for the patch, but there are two issues that should be fixed:

(1) stat => fstat
(2) change the subject to mean that this is not AIX specific (`[LLVM][Support] 
Report EISDIR when opening a directory on AIX`). Other OSes including Linux are 
changed as well.

I think `trySimplifyPath()` is not particularly relevant as it just performs a 
simple canonicalization (removal of `.` and `..` path components without regard 
for symlink traversal) and case insensitive comparison with the remaining 
components with a "real" path that is presumed to already be devoid of such 
components. It is therefore sensitive to structure, but only for the (non-`.` 
and non-`..`) components present in the (non-real) `Components` vector; the 
"real" path may have more leading components (the `Components` vector may 
represent a relative path). The presence of a substitute drive in the "real" 
path won't contribute to a structural difference unless the `Components` vector 
is absolute but with a drive other than the substitute drive or if it is 
relative but starting at a higher directory level than the substitute drive; 
neither of which should be the case for this test when `%t` is consistently 
used.

The only relevant user path

FMADD, FMSUB instructions perform better or the same compared to indexed
FMLA, FMLS.

For example, the Arm Cortex-A55 Software Optimization Guide lists "FP
multiply accumulate" FMADD, FMSUB instructions with a throughput of 2
IPC, whereas it lists "ASIMD FP multiply accumulate, by element" FMLA,
FMLS with a throughput of 1 IPC.

The Arm Cortex-A77 Software Optimization Guide, however, does not
separately list "by element" variants of the "ASIMD FP multiply
accumulate" instructions, which are listed with the same throughput of 2
IPC as "FP multiply accumulate" instructions.

[PATCH] D154869: [Flang] [FlangRT] Implement FlangRT library as solution to Flang's runtime LLVM integration

The test changes look good to me.

This `add_compile_options(-fPIC)` shouldn't be necessary?

I don't think most checkers depend on value ranges explicitly, except for a 
handful of checkers maybe. So, I don't think it's such a huge deal, but I agree 
that it's a problem.
I would bet that the StdLibraryFunctionsChecker would suffer from the same 
issue, and the OOB checker(s) along with it.
I don't know of heuristics mitigating the damage.

I don't think we should do anything about it unless it's frequent enough.
Try to come up with a heuristic to be able to measure how often this happens, 
if you really care.
Once you have a semi-working heuristic for determining if that bugpath suffers 
from this, you can as well use it for marking the bugreport invalid if that's 
the case to lean towards suppressing those FPs.

I don't think it's completely necessary to fix those FPs to land this. I think 
of that as an improvement, on top of this one.
I hope I clarified my standpoint.




Comment at: clang/test/Analysis/bitwise-shift-sanity-checks.c:70-74
+  if (right < 0)
+return 0;
+  return left << (right + 32);
+  // expected - warning@-1 {{Left shift overflows the capacity of 'int'}}
+  // expected-warning@-2 {{Right operand is negative in left shift}}

Let's be explicit about the actual assumed value range, and use 
`clang_analyzer_value()`.
I also recommend using an explicit FIXME for calling out what should be there, 
instead of abusing a non-matching `expected` pattern. I know I used that in the 
past, and probably seen it from me. I feel ashamed that I did that. I know I 
did that to have cleaner diffs, once fixed, but I honestly think it does more 
harm than good.

[PATCH] D154869: [Flang] [FlangRT] Implement FlangRT library as solution to Flang's runtime LLVM integration

[Paul Scoropan via Phabricator via cfe-commits]

pscoro added a comment.

In order to keep the scope of this patch manageable, and because further 
discussion is warranted first, no source files have been moved from flang into 
flang-rt. Although I would imagine that this may be something we would want to 
do in the future in order to continue our efforts at decoupling compiler and 
runtime.

[PATCH] D155773: [llvm][MemoryBuiltins] Add alloca support to getInitialValueOfAllocation

[John McIver via Phabricator via cfe-commits]

jmciver added a comment.

@nikic Thanks for responding. I will get a "work in progress" patch up in the 
next three days.

In the API adaptation, instruction insertion is still being handled in the 
caller as some passes are only allowed removal and not insertion.

[PATCH] D154869: [Flang] [FlangRT] Implement FlangRT library as solution to Flang's runtime LLVM integration

[Paul Scoropan via Phabricator via cfe-commits]

pscoro added a comment.

Some of the testcases have been reformatted by clang-format when I updated the 
patch with arcanist. If the community is against introducing extra changes like 
these I would be happy to re-update my patch without clang-formatting these 
files.
