Nemanja Ivanovic 10e2b5dcaa [Power9] Builtins for ELF v.2 ABI conformance - front end portion
This patch corresponds to review:
https://reviews.llvm.org/D24397

It adds the __POWER9_VECTOR__ macro and the -mpower9-vector option along with
a number of altivec.h functions (refer to the code review for a list).

Daniel Jasper e31388aee9 [clang-format] Don't allow newline after uppercase Obj-C block return types
Fixes the following:
  BOOL (^aaa)(void) = ^BOOL {
  };

The first BOOL's token was getting set to TT_FunctionAnnotationRParen
incorrectly, which was causing an unexpected newline after (^aaa). This
was introduced in r245846.

Saleem Abdulrasool eae64f8a62 headers: add missing Windows ARM Interlocked intrinsics
On ARM, there are multiple versions of each of the intrinsics, with
acquire/relaxed/release barrier semantics.

The newly added ones are provided as inline functions here instead of builtins,
since they should only be available on certain archs (arm/aarch64).

This is necessary in order to compile C++ code for ARM in MSVC mode.

Teresa Johnson 12286d22b7 [LTO] Add -flto-jobs=N to control backend parallelism
Summary:
Currently, a linker option must be used to control the backend
parallelism of ThinLTO. The linker option varies depending on the
linker (e.g. gold vs ld64). Add a new clang option -flto-jobs=N
to control this.

I've added in the wiring to pass this to the gold plugin. I also
added in the logic to pass this down in the form I understand that
ld64 uses on MacOS, for the darwin target.

Renato Golin fa007aeef4 Revert "set the underlying value of “#pragma STDC FP_CONTRACT” on by default"
This reverts commit r282259, as it broke the AArch64 test-suite bots.

llvm-svn: 282289
2016-09-23 20:32:52 +00:00
Sebastian Pop 6919ae5abc set the underlying value of “#pragma STDC FP_CONTRACT” on by default
Clang has the default FP contraction setting of “-ffp-contract=on”, which
doesn't really mean “on” in the conventional sense of the word, but rather
really means “according to the per-statement effective value of the relevant
pragma”.

Before this patch, Clang has that pragma defaulting to “off”. Since the
“-ffp-contract=on” mode is really an AND of two booleans and the second of them
defaults to “off”, the whole thing effectively defaults to “off”. This patch
changes the default value of the pragma to “on”, thus making the default pair of
booleans (on, on) rather than (on, off). This makes FP optimization slightly
more aggressive than before when not using either “-Ofast”, “-ffast-math”, or
“-ffp-contract=fast”. Even with this patch the compiler still respects
“-ffp-contract=off”.

As per a suggestion by Steve Canon, the added code does _not_ require “-O3” or
higher. This is so as to try our best to preserve identical floating-point
results for unchanged source code compiling for an unchanged target when only
changing from any optimization level in the set (“-O0”, “-O1”, “-O2”, “-O3”) to
any other optimization level in that set. “-Os” and “-Oz” seem to be behaving
identically, i.e. should probably be considered a part of the aforementioned
set, but I have not reviewed this rigorously. “-Ofast” is explicitly _not_ a
member of that set.

Summary:
The ASAN unittests are failing (check-asan-dynamic) due to an incorrect symbol name:
```
LINK : error LNK2001: unresolved external symbol ___asan_seh_interceptor

On win64, the linker is not adding an extra underscore. This was correctly fixed in the same file for other uses.

After that patch, most of the unittests are passing, but some related to SEH needs to be fixed.

Anna Zaks c154f7bc37 [analyzer] Add a checker that detects blocks in critical sections
This checker should find the calls to blocking functions (for example: sleep, getc, fgets,read,recv etc.) inside a critical section. When sleep(x) is called while a mutex is held, other threads cannot lock the same mutex. This might take some time, leading to bad performance or even deadlock.

Example:

mutex_t m;

void f() {
  sleep(1000); // Error: sleep() while m is locked! [f() is called from foobar() while m is locked]
  // do some work
}

void foobar() {
  lock(m);
  f();
  unlock(m);
}
