* Fix Threading path when LLVM_ENABLE_THREADS=0.Zachary Turner2017-03-031-1/+1

* Try again to appease the FreeBSD bot.Zachary Turner2017-03-031-7/+2
| | | | | | | The actual logic was wrong, not just the type conversion. This should get it correct. llvm-svn: 296899
* Try to appease the FreeBSD bots.Zachary Turner2017-03-031-2/+2
| | | | | | | | pthread_self() returns a pthread_t, but we were setting it to an int. It seems the cast to int when calling sysctl is still the correct thing to do, though. llvm-svn: 296892
* Don't bring in llvm/Support/thread.h in Threading.cppZachary Turner2017-03-031-2/+8
| | | | | | | | | | | | Doing so defines the type llvm::thread. On FreeBSD, we need to call a macro which references its own ::thread type, which causes an ambiguity due to ADL when inside of the llvm namespace. Since we don't even need this unless LLVM_ENABLE_THREADS == 1, we don't even need this type anyway, as it is always equal to std::thread, so we can just use that directly. llvm-svn: 296891

* [Support] Provide access to current thread name/thread id.Zachary Turner2017-03-033-84/+311
| | | | | | | | | | | | | | | | Applications often need the current thread id when making system calls, and some operating systems provide the notion of a thread name, which can be useful in enabling better diagnostics when debugging or logging. This patch adds an accessor for the thread id, and "best effort" getters and setters for the thread name. Since this is non critical functionality, no error is returned to indicate that a platform doesn't support thread names. Differential Revision: https://reviews.llvm.org/D30526 llvm-svn: 296887

* [APInt] Optimize APInt creation from uint64_tCraig Topper2017-03-011-0/+1
| | | | | | | | | | | | | | | | | Summary: This patch moves the clearUnusedBits calls into the two different initialization paths for APInt from a uint64_t. This allows the compiler to better optimize the clearing of the unused bits for the single word case. And it puts the clearing for the multi word case into the initSlowCase function to save code. In the common case of initializing with 0 this allows the clearing to be completely optimized out for the single word case. On my local x86 build this is showing a ~45kb reduction in the size of the opt binary.

* Process tilde in llvm::sys::path::nativeSerge Pavlov2017-03-011-0/+8
| | | | | | | | | | | | | Windows does not treat `~` as a reference to home directory, so the call to `llvm::sys::path::native` on, say, `~/somedir` produces `~\somedir`, which has different meaning than the original path. With this change tilde is expanded on Windows to user profile directory. Such behavior keeps original meaning of the path and is consistent with the algorithm of `llvm::sys::path::home_directory`.

* [APInt] Add APInt::extractBits() method to extract APInt subrange (reapplied)Simon Pilgrim2017-02-251-0/+36
| | | | | | | | | | | | | | | | The current pattern for extract bits in range is typically: Mask.lshr(BitOffset).trunc(SubSizeInBits); Which can be particularly slow for large APInts (MaskSizeInBits > 64) as they require the allocation of memory for the temporary variable.

| | | | | | | | | | | | | | | | | | The current pattern for setting bits in range is typically: Mask |= APInt::getBitsSet(MaskSizeInBits, LoPos, HiPos); Which can be particularly slow for large APInts (MaskSizeInBits > 64) as they require the allocation memory for the temporary variable. This is one of the key compile time issues identified in PR32037. This patch adds the APInt::setBits() helper method which avoids the temporary memory allocation completely, this first implementation uses setBit() internally instead but already significantly reduces the regression in PR32037 (~10% drop). Additional optimization may be possible. I investigated whether there is need for APInt::clearBits() and APInt::flipBits() equivalents but haven't seen these patterns to be particularly common, but reusing the code would be trivial.

* [Support] Re-add the special OSX flags on mmap.Zachary Turner2017-02-221-0/+19

* [Support] Provide linux/magic.h fallback for older kernelsMichal Gorny2017-02-221-0/+15
| | | | | | | | | | | | | | | | | | | | | The function for distinguishing local and remote files added in r295768 unconditionally uses linux/magic.h header to provide necessary filesystem magic numbers. However, in kernel headers predating 2.6.18 the magic numbers are spread throughout multiple include files. Furthermore, LLVM did not require kernel headers being installed so far. To increase the portability across different versions of Linux kernel and different Linux systems, add CMake header checks for linux/magic.h and -- if it is missing -- the linux/nfs_fs.h and linux/smb.h headers which contained the numbers previously. Furthermore, since the numbers are static and the feature does not seem critical enough to make LLVM require kernel headers at all, add fallback constants for the case when none of the necessary headers is available.

* Add initial support for debug countingDaniel Berlin2017-02-192-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: We have support for bisection, and bugpoint can reduce testcases often to a single pass. But that doesn't help reduce it to a single transform by a single pass. Which debug counting lets us do. Debug counting lets you instrument a pass so that it only executes a certain thing (rwhatever you want) after skipping it a certain time of times, and then only does a certain number of executions before saying "skip" again. To make it concrete, for predicateinfo, if i instrument use renaming, i can make it so it skips renaming the first N uses, renames the next N, and then skips the rest. This lets you narrow down a miscompilation to, often, a single transformation, and then also debug it (by using the same command line parameters).

* [CMake] Fix pthread handling for out-of-tree buildsEric Fiselier2017-02-101-1/+1
| | | | | | | | | | | | | | | LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects to correctly link the threading library when needed. Unfortunately `PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed and therefore can't be used when configuring out-of-tree builds. This causes such builds to fail since `pthread` isn't being correctly linked. This patch attempts to fix that problem by renaming and exporting `LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB` because It seemed likely to cause collisions with downstream users of `LLVMConfig.cmake`. llvm-svn: 294690
