5 years ago[Driver] Prioritize SYSROOT/usr/include over RESOURCE_DIR/include on linux-musl

[Driver] Prioritize SYSROOT/usr/include over RESOURCE_DIR/include on linux-musl

On a musl-based Linux distribution, stdalign.h stdarg.h stdbool.h stddef.h stdint.h stdnoreturn.h are expected to be provided by musl (/usr/include), instead of RESOURCE_DIR/include.
Reorder RESOURCE_DIR/include to fix the search order problem.
(Currently musl doesn't provide stdatomic.h. stdatomic.h is still found in RESOURCE_DIR/include.)

gcc on musl has a similar search order:

```
 /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/../../../../include/c++/8.3.0
 /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/../../../../include/c++/8.3.0/x86_64-alpine-linux-musl
 /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/../../../../include/c++/8.3.0/backward
 /usr/local/include
 /usr/include/fortify
 /usr/include
 /usr/lib/gcc/x86_64-alpine-linux-musl/8.3.0/include
```

This is different from a glibc-based distribution where RESOURCE_DIR/include is placed before SYSROOT/usr/include.

According to the maintainer of musl:

> musl does not support use/mixing of compiler-provided std headers with its headers, and intentionally has no mechanism for communicating with such headers as to which types have already been defined or still need to be defined. If the current include order, with clang's headers before the libc ones, works in some situations, it's only by accident.

5 years ago[clang][DirectoryWatcher] Adding llvm::Expected error handling to create.
Puyan Lotfi [Tue, 6 Aug 2019 05:12:23 +0000 (05:12 +0000)]
[clang][DirectoryWatcher] Adding llvm::Expected error handling to create.

Prior to this patch Unix style errno error reporting from the inotify layer was
used by DirectoryWatcher::create to simply return a nullptr on error. This
would generally be ok, except that in LLVM we have much more robust error
reporting through the facilities of llvm::Expected.

The other critical thing I stumbled across was that the unit tests for
DirectoryWatcher were not failing abruptly when inotify_init() was reporting an
error, but would continue with the testing and eventually hit a deadlock in a
pathological machine state (ie in the unit test, the return nullptr on ::create
was ignored).

Generally this pathological state never happens on any build bot, so it is
totally understandable that it was overlooked, but on a Linux desktop running
a dubious desktop environment (which I will not name) there is a chance that
said desktop environment could use up enough inotify instances to exceed the
user's limit. These are the conditions that led me to hit the deadlock I am
addressing in this patch with more robust error handling.

With the new llvm::Expected error handling when your system runs out of inotify
instances for your user, the unit test will be forced to handle the error or
crash and report the issue to the user instead of weirdly deadlocking on a
condition variable wait.

namespaces without the outdirectory. So if the info is in the global
namespace the path would be empty and the old check wouldn't work as expected.
A new attribute has been added to the Reference struct that indicates if
the info's parent is the global namespace.

5 years ago[WebAssembly] Fix conflict between ret legalization and sjlj
Keno Fischer [Mon, 5 Aug 2019 21:36:09 +0000 (21:36 +0000)]
[WebAssembly] Fix conflict between ret legalization and sjlj

Summary:
When the WebAssembly backend encounters a return type that doesn't
fit within i32, SelectionDAG performs sret demotion, adding an
additional argument to the start of the function that contains
a pointer to an sret buffer to use instead. However, this conflicts
with the emscripten sjlj lowering pass. There we translate calls like:

```
call {i32, i32} @foo()
```

into (in pseudo-llvm)
```
%addr = @foo
call {i32, i32} @__invoke_{i32,i32}(%addr)
```

i.e. we perform an indirect call through an extra function.
However, the sret transform now transforms this into
the equivalent of
```
        %addr = @foo
        %sret = alloca {i32, i32}
        call {i32, i32} @__invoke_{i32,i32}(%sret, %addr)
```
(while simultaneously translation the implementation of @foo as well).
Unfortunately, this doesn't work out. The __invoke_ ABI expected
the function address to be the first argument, causing crashes.

There is several possible ways to fix this:
1. Implementing the sret rewrite at the IR level as well and performing
   it as part of lowering to __invoke
2. Fixing the wasm backend to recognize that __invoke has a special ABI
3. A change to the binaryen/emscripten ABI to recognize this situation

This revision implements the middle option, teaching the backend to
treat __invoke_ functions specially in sret lowering. This is achieved
by
1) Introducing a new CallingConv ID for invoke functions
2) When this CallingConv ID is seen in the backend and the first argument
   is marked as sret (a function pointer would never be marked as sret),
   swapping the first two arguments.

FuzzedDataProvider is a helper class for writing fuzz targets that fuzz

different coverage instrumentation modes. Therefore, making this FDP class a

and distribute fuzz targets across different projects, build systems, etc.

In a proprietary benchmark we see a performance drop of about 12% on PNG
compression before this patch, though it passes all tests.

This patch mirrors X86 for AArch64 and initializes
`TTI::MemCmpExpansionOptions()` to then expand calls to `bcmp()` when
appropriate.  No tuning of the parameters was performed, but, at this point,
it's enough to recover the performance drop above.

This problem also exists on ARM.  Once a consensus is reached for AArch64, we
can work to fix ARM as well.

5 years ago[AArch64] Set preferred function alignment to 16 bytes on Neoverse N1
Pablo Barrio [Mon, 5 Aug 2019 17:38:58 +0000 (17:38 +0000)]
[AArch64] Set preferred function alignment to 16 bytes on Neoverse N1

Summary:
The Arm Neoverse N1 Software Optimization Guide [1], Section "4.8 Branch
instruction alignment" states:

"Consider aligning subroutine entry points and branch targets to 32B
boundaries, within the bounds of the code-density requirements of the
program."

This patch sets the preferred function alignment on Neoverse N1 to 2^4=16B.
This was already the case in some of the latest Cortex-A CPUs. Benchmarking
in previous Cortex-A CPUs suggested that 16B alignment is already better
than the default. See commit d04ee305.

The reason we don't set it to 32B right now (as the optimisation guide
suggests) is that this will impact code size and perhaps the instruction
cache performance. Therefore we need benchmark numbers first.

I have also added testing for A75 and A76 that we were missing.
