* ADT: Correct APInt::getActiveWords for zero valuesMeador Inge2013-02-071-0/+8
| | | | | | | | | | PR15138 was opened because of a segfault in the Bitcode writer. The actual issue ended up being a bug in APInt where calls to APInt::getActiveWords returns a bogus value when the APInt value is 0. This patch fixes the problem by ensuring that getActiveWords returns 1 for 0 valued APInts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174641 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce a new data structure, the SparseMultiSet, and changes to the MI ↵Michael Ilseman2013-01-212-0/+236
| | | | | | | | | | scheduler to use it. A SparseMultiSet adds multiset behavior to SparseSet, while retaining SparseSet's desirable properties. Essentially, SparseMultiSet provides multiset behavior by storing its dense data in doubly linked lists that are inlined into the dense vector. This allows it to provide good data locality as well as vector-like constant-time clear() and fast constant time find(), insert(), and erase(). It also allows SparseMultiSet to have a builtin recycler rather than keeping SparseSet's behavior of always swapping upon removal, which allows it to preserve more iterators. It's often a better alternative to a SparseSet of a growable container or vector-of-vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173064 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce llvm::sys::getProcessTriple() function.Peter Collingbourne2013-01-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | In r143502, we renamed getHostTriple() to getDefaultTargetTriple() as part of work to allow the user to supply a different default target triple at configure time. This change also affected the JIT. However, it is inappropriate to use the default target triple in the JIT in most circumstances because this will not necessarily match the current architecture used by the process, leading to illegal instruction and other such errors at run time. Introduce the getProcessTriple() function for use in the JIT and its clients, and cause the JIT to use it. On architectures with a single bitness, the host and process triples are identical. On other architectures, the host triple represents the architecture of the host CPU, while the process triple represents the architecture used by the host CPU to interpret machine code within the current process. For example, when executing 32-bit code on a 64-bit Linux machine, the host triple may be 'x86_64-unknown-linux-gnu', while the process triple may be 'i386-unknown-linux-gnu'. This fixes JIT for the 32-on-64-bit (and vice versa) build on non-Apple platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wall time, user time, and system time since a process started. For walltime, we currently use TimeValue's interface and a global initializer to compute a close approximation of total process runtime. For user time, this adds support for an somewhat more precise timing mechanism -- clock_gettime with the CLOCK_PROCESS_CPUTIME_ID clock selected. For system time, we have to do a full getrusage call to extract the system time from the OS. This is expensive but unavoidable. In passing, clean up the implementation of the old APIs and fix some latent bugs in the Windows code. This might have manifested on Windows ARM systems or other systems with strange 64-bit integer behavior. The old API for this both user time and system time simultaneously from a single getrusage call. While this results in fewer system calls, it also results in a lower precision user time and if only user time is desired, it introduces a higher overhead. It may be worthwhile to switch some of the pass timers to not track system time and directly track user and wall time. The old API also tracked walltime in a confusing way -- it just set it to the current walltime rather than providing any measure of wall time since the process started the way buth user and system time are tracked. The new API is more consistent here. The plan is to eventually implement these methods for a *child* process by using the wait3(2) system call to populate an rusage struct representing the whole subprocess execution. That way, after waiting on a child process its stats will become accurate and cheap to query. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171551 91177308-0d34-0410-b5e6-96231b3b80d8

This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project.
