The `include_next` question is still open.  Any preference here?

IMO, since the standard explicitly delegates to the compiler builtin when 
available, we may not need to `include_next` - unless there are other 
conventions around this.

[PATCH] D112349: [Verifier] Add verification logic for GlobalIFuncs

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added subscribers: pirama, srhines, kongyi.
pirama added a comment.

Unrelated to missing resolver definition, this change doesn't accommodate 
resolvers that take parameters.  (Curiously, this verification only fails with 
ThinLTO).

  // with -flto=full or without -flto=thin, below command works
  $ clang -shared ifunc.cpp -fPIC -fuse-ld=lld -flto=thin
  IFunc resolver has incorrect type
  i32 ()* @_Z5ifuncv
  
  $ cat ifunc.cpp
  #include 
  
  typedef int (*fn_ptr_t)();
  
  int ifunc() __attribute__((ifunc("resolver")));
  
  int ret42() {
return 42;
  }
  
  extern "C" fn_ptr_t resolver(uint64_t hwcap) {
return ret42;
  }

I have a change that fixes the above use case but causes some opaque pointer 
tests to fail.  I'll investigate and upload once they're fixed.

I also noticed that this patch didn't add any test for the "IFunc resolver has 
incorrect type" errors cases.  It'd be good to add those in a follow-up.

[PATCH] D113840: [Driver][Android] Remove unneeded isNoExecStackDefault

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama edited reviewers, added: srhines; removed: pirama.
pirama added a comment.

Will defer to Dan's review.  I think these changes are safe for the Android 
platform (where we only use lld).  The NDK only supports lld but that does not 
preclude external users from using other linkers.

This fixes PR46992.

Git stores symlinks as text files and we should not format them even if
they have one of the requested extensions.

(Move the call to `cd_to_toplevel()` up a few lines so we can also print
the skipped symlinks during verbose output.)

[PATCH] D78033: [cmake] Restrict symbols exported from libclang-cpp

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

I wanted to avoid this since `libLLVM` is an optional target but `libclang-cpp` 
is built by default.  Maybe I didn't think through all options in this regard.

1. We could build `libLLVM` by default, but don't install it unless requested.
2. Or link `libclang-cpp` against `libLLVM` iff the latter is built.

Either option would require a CMake change that I am not sure how to make.  We 
would need to remove LLVM static libraries from `libclang-cpp`'s link command 
but I cannot figure out how to accomplish this.  They are getting included 
transitively via CMake's dependency graph.

Another option is to make libclang-cpp a superset of Clang and LLVM libraries.  
This would however require using `--whole-archive` similar to `libLLVM.so`.

Do you have any preferred solution and pointers on how to filter out some 
dependencies in CMake?  One hacky way could be to add a special-case in 
`AddLLVM.cmake` and dedup right before `target_link_libraries()`.

[PATCH] D78033: [cmake] Restrict symbols exported from libclang-cpp

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: beanz, mgorny.
Herald added a project: clang.
Herald added a subscriber: cfe-commits.

In libclang-cpp, export only symbols from the clang namespace or clang_*
(functions for the C interface).  This fixes the use case where a tool
depends on both libclang-cpp and libLLVM.  Without this change,
command-line registries from libLLVMSupport are exported by libclang-cpp
and gets deduped with symbols of the same name from libLLVM .  But, the
arguments get registered separately from both the libraries during
startup, resulting in an error.

[PATCH] D67200: Add -static-openmp driver option

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

I'll update this review addressing @Joerg's reply to cfe-commits:

> Needs testing for the -static interaction?

Thanks @srhines for pointing me to it - I'd only subscribed to cfe-dev and not 
cfe-commits so I'd missed it..

Done.

Thanks Fangrui!  That change would be very helpful and I'll move to 
`-static=openmp` once it lands.  As for this change, I'll wait over the weekend 
and submit it on Monday to allow everyone a chance to look at it.

[PATCH] D53238: [Driver] Add -static= to unify -static-{libgcc,libstdc++}

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

Does this regress from existing behavior for unused arguments?  Currently, 
`-static-libstdc++ -nostdlib` issues an unused argument warning for 
`-static-libstdc++`, while AFAICT `-static=c++stdlib -nostdlib` doesn't.

I'm not exactly sure how/where to issue this warning, though.

[PATCH] D67200: Add -static-openmp driver option

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: Hahnfeld, danalbert, srhines, joerg.
Herald added a subscriber: guansong.
Herald added a reviewer: jdoerfert.
Herald added a project: clang.

This option forces linking with the static OpenMP host runtime (similar
to -static-libgcc and -static-libstdcxx).

Android's NDK will start the shared OpenMP runtime in addition to the static
libomp.  In this scenario, the linker will prefer to use the shared library by
default.  Add this option to enable linking with the static libomp.

[PATCH] D63889: Check possible warnings on global initializers for reachability

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added inline comments.



Comment at: clang/include/clang/Sema/AnalysisBasedWarnings.h:111
+void emitPossiblyUnreachableDiags(Sema , AnalysisDeclContext ,
+SmallVector PossiblyUnreachableDiags);
+

Fix indentation.



Comment at: clang/lib/Sema/AnalysisBasedWarnings.cpp:2007
+static void flushDiagnostics(Sema ,
+SmallVector PossiblyUnreachableDiags) 
{
+  for (const auto  : PossiblyUnreachableDiags)

Should `PossiblyUnreachableDiags` be const?

Also, fix indentation.



Comment at: clang/lib/Sema/AnalysisBasedWarnings.cpp:2015
+
+  if (!PossiblyUnreachableDiags.empty()) {
+bool analyzed = false;

How about returning early if `PossiblyUnreachableDiags` here is empty?  That'll 
avoid putting the entire logic of this function in the `true` branch.



Comment at: clang/lib/Sema/AnalysisBasedWarnings.cpp:2031
+  CFGReverseBlockReachabilityAnalysis *cra =
+  AC.getCFGReachablityAnalysis();
+  // FIXME: We should be able to assert that block is non-null, but

`getCFGReachablityAnalysis` has a typo.  It's missing an 'i'.  Consider fixing 
this in a separate patch.



Comment at: clang/lib/Sema/AnalysisBasedWarnings.cpp:2051
+
+if (!analyzed)
+  flushDiagnostics(S, PossiblyUnreachableDiags);

Rewrite this as the `else` clause for `if (AC.getCFG())`?  In the current 
structure, it's not immediately clear that `flushDiagnostics` is called iff 
`AC.getCFG()` fails to return a valid CFG.

Upon further reading, this seems to be refactored from another function below 
so it probably makes sense to leave it as-is.

[PATCH] D50359: Add a new library, libclang-cxx

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

As I mentioned in the discussion, we decided to carry build rules for the 
proposed library in downstream.  I've updated this to make it more general, and 
will leave it open in case there's more interest to revive it in the future.

I tried to be defensive here in case the default changes in the future.  I can 
simplify to just return true here if that'd be simpler.

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: rsmith, srhines.

Android uses jemalloc allocator, which returns 8-byte-aligned pointers for
allocations smaller than 8 bytes for 64-bit architectures.  Set NewAlign
conservatively to 8 bytes.

[PATCH] D50467: [SEMA] add more -Wfloat-conversion to compound assigment analysis

+->getAs();
+  if (!ResultBT || !(RBT && RBT->isFloatingPoint())) return;
+

Add a comment explaining this conditional as well?  

> Return if source and target types are unavailable or if source is not a 
> floating point.

With the comment, it might be cleaner to read if you expand the negation: 
`!ResultBT || !RBT || !RBT->isFloatingPoint()`

[PATCH] D50359: Add a new library, libclang-cxx

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
Herald added a subscriber: mgorny.

The current libclang.so exports only the symbols required for the stable
C api.  This is opposed to libLLVM.so, which exports all the symbols
from the LLVM libraries, including those from the C++ API.  This patch
adds libclang-cxx.so that is similar to libLLVM.so and exports all
symbols from the clang libraries.  The motivation for this library is to
be used by Clang tools that use Clang's C++ api.  They no longer need to
link against the individual static libraries.

[PATCH] D37302: [Headers] Define *_HAS_SUBNORM for FLT, DBL, LDBL

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

Sorry this fell of my radar.  I've rebased the patch.

Since this has been inactive for a while, lets wait for a couple of days to see 
if there are any other comments.  If there are no objections, I'll submit this 
on Wednesday.

[PATCH] D50199: [MinGW] Predefine UNICODE if -municode is specified during compilation

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

In https://reviews.llvm.org/D50199#1186164, @rnk wrote:

It seems odd to include predefined macros at the driver, which AFAIK is just a 
bridge to the frontend's command-line interface.  OTOH, there is other 
precedence for doing this - during clang-cl's argument processing.  So I don't 
have a strong opinion here.

[PATCH] D48749: [Win32] Overload ==, != for locale_t and long long

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: mstorsjo, EricWF, srhines, danalbert.
Herald added subscribers: ldionne, christof.

_is_chartype_l (needed for isxdigit_l) in MinGW compares locale_t and NULL.
NULL is 'long long' for 64-bit, and this results in ambiguous overloads when
compiled with Clang.  Define a concrete overload for the operators to fix the
ambiguity.

[PATCH] D48743: Make pthread's __libcpp_get_tls declaration consistent

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: EricWF, srhines, danalbert.
Herald added subscribers: ldionne, christof.

Add the _LIBCPP_TLS_DESTRUCTOR_CC attribute to the __at_exit parameter
for the pthread definition of __libcpp_get_tls.  This makes it
consistent with the rest (the non-pthread declaration in
include/__threading_support, and calls in include/thread and
srcsrc/support/win32/thread_win32.cpp).

This has NFC because _LIBCPP_TLS_DESTRUCTOR_CC is empty when pthread is
available.

[PATCH] D48742: Set _LIBCPP_TLS_DESTRUCTOR_CC convention to run_dtors

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: EricWF, srhines, danalbert.
Herald added subscribers: ldionne, christof.

This function is passed as the __at_exit parameter to
__libcpp_tls_create.  This parameter is marked with the
_LIBCPP_TLS_DESTRUCTOR_CC attribute.  The macro is empty for pthread,
and set to __stdcall for other threading models.  __stdcall is in turn
emptry for most cases.  That's likely why this doesn't fail now.

The one exception is Windows on i686 with the Win32 threading API, where
the stdcall calling convention is used.

Use _LIBCPP_MSVCRT_LIKE while configuring ELAST, so MinGW gets the same
configuration as MSVC.

[PATCH] D45145: [Driver] Wire up the -f[no-]rtlib-add-rpath flag and tests

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

Hi Petr, thanks for the fix (I dropped the ball on this one :( ).  Instead of 
duplicating the checks, does it make sense to fold check into 
addArchSpecificRPath and rename it to 'addArchSpecificRPathIfRequested' or 
something similar?

[PATCH] D44852: [CodeGen] Mark fma as const for Android

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.
pirama added reviewers: spatel, efriedma, srhines, chh, enh.
Herald added a subscriber: cfe-commits.

r318093 sets fma, fmaf, fmal as const for Gnu and MSVC.  Android also
does not set errno for these functions.  So mark these const for
Android.

[PATCH] D40476: Switch kryo to use -mcpu=cortex-a57 when invoking the assembler

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama created this revision.

Using -no-integrated-as causes -mcpu=kryo to fail since GNU assembler
doesn't recognize kryo.  Cortex-a57 is the closest CPU to kryo that the
assembler does recognize.  So we should switch the assembler to use
that instead.

[PATCH] D37302: [Headers] Define *_HAS_SUBNORM for FLT, DBL, LDBL

Clang defines `__FLT_HAS_DENORM__` and friends unconditionally, so I thought we 
could do this for `FLT_HAS_SUBNORM` as well, considering that gcc did the same. 
 But that might be misleading because gcc's float.h was just for the target of 
that particular gcc build.

Am I right to understand that `__FLT_HAS_DENORM__` signifies *compiler* support 
for denorms as opposed to support on the *platforms* supported?  If so, it 
might support our alternative consideration of defining these macros in the 
bionic/libc headers for Android (and rely on the include_next similar to 
Windows and Darwin).

@bruno Any suggestion on how to update test/Headers/float-darwin,c* so make it 
check the include_next?  I am unable to find the darwin-specific float.h inside 
an XCode installation directory.

Maybe I wasn't clear.  I suggest that we don't set 
RUNTIMES_${target}_LLVM_ENABLE_ASSERTIONS to ON here and rather initialize it 
based on another flag.  I was incorrect to suggest we reuse 
LLVM_ENABLE_ASSERTIONS.  We should rather have something like 
ANDROID_RUNTIMES_ENABLE_ASSERTIONS.

The motivation is to reduce the number of additional flags/switches, under the 
assumption that assert-enabled or assert-disabled builds of the runtimes are 
generated simultaneously.

To generate assert-enabled builds, the invocation would be:

```
$ cmake ... -DANDROID_RUNTIMES_ENABLE_ASSERTIONS=ON

```
instead of

```
$ cmake ... -DRUNTIMES_armv7-linux-android_LLVM_ENABLE_ASSERTIONS=ON 
-DRUNTIMES-aarch64-linux-android_LLVM_ENABLE_ASSERTIONS=ON ...

```
If I understand CMake correctly, we can still enable assertions only for a 
particular target by:

```
$ cmake ...  -DANDROID_RUNTIMES_ENABLE_ASSERTIONS=OFF 
-DRUNTIMES-aarch64-linux-android_LLVM_ENABLE_ASSERTIONS=ON
```

Should we initialize it to LLVM_ENABLE_ASSERTIONS rather than defaulting to ON? 
 So assertions can be enabled/disabled for all targets with just one switch 
(and then over-ride with per-target flags, if necessary).

[PATCH] D30920: Do not pass -Os and -Oz to the Gold plugin

[Pirama Arumuga Nainar via Phabricator via cfe-commits]

pirama added a comment.

From the discussion, it seems it is theoretically feasible to make optimization 
for speed a function-level attribute as well.  After looking at the 
PassMangerBuilder for this bug, I think that'll make the optimization passes 
cleaner by keeping the passes and their behavior at various levels in one place.

Circling back to the issue at hand, what is the best way to handle Os and Oz at 
the lto stage?  I think we left off with @mehdi_amini's comment that the driver 
should emit a warning when dropping the Os/Oz.

The driver (accepts, but) ignores Os and other optimization flags for non-lto 
link-only actions.  That it has an effect for LTO is seems to be an 
implementation detail.  Since optimization flags are compiler-only options, and 
Clang already silently (without a warning) ignores these flags during link-only 
invocations, silently transforming them when passing to the plugin seems 
reasonable.
