* [PowerPC] Do not use BLA with the 64-bit SVR4 ABIUlrich Weigand2014-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The PowerPC back-end uses BLA to implement calls to functions at known-constant addresses, which is apparently used for certain system routines on Darwin. However, with the 64-bit SVR4 ABI, this is actually incorrect. An immediate function pointer value on this platform is not directly usable as a target address for BLA: - in the ELFv1 ABI, the function pointer value refers to the *function descriptor*, not the code address - in the ELFv2 ABI, the function pointer value refers to the global entry point, but BL(A) would only be correct when calling the *local* entry point This bug didn't show up since using immediate function pointer values is not usually done in the 64-bit SVR4 ABI in the first place. However, I ran into this issue with a certain use case of LLVM as JIT, where immediate function pointer values were uses to implement callbacks from JITted code to helpers in statically compiled code. Fixed by simply not using BLA with the 64-bit SVR4 ABI. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211174 91177308-0d34-0410-b5e6-96231b3b80d8
* [PowerPC] Fix emitting instruction pairs on LEUlrich Weigand2014-06-18
| | | | | | | | | | | | | | | My patch r204634 to emit instructions in little-endian format failed to handle those special cases where we emit a pair of instructions from a single LLVM MC instructions (like the bl; nop pairs used to implement the call sequence). In those cases, we still need to emit the "first" instruction (the one in the more significant word) first, on both big and little endian, and not swap them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211171 91177308-0d34-0410-b5e6-96231b3b80d8

* DAG: move sret demotion into most basic LowerCallTo implementation.Tim Northover2014-06-18
| | | | | | | | | | | | | | | | It looks like there are two versions of LowerCallTo here: the SelectionDAGBuilder one is designed to operate on LLVM IR, and the TargetLowering one in the case where everything is at DAG level. Previously, only the SelectionDAGBuilder variant could handle demoting an impossible return to sret semantics (before delegating to the TargetLowering version), but this functionality is also useful for certain libcalls (e.g. 128-bit operations on 32-bit x86). So this commit moves the sret handling down a level. rdar://problem/17242889 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211155 91177308-0d34-0410-b5e6-96231b3b80d8

* Random Number Generator (llvm)JF Bastien2014-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Provides an abstraction for a random number generator (RNG) that produces a stream of pseudo-random numbers. The current implementation uses C++11 facilities and is therefore not cryptographically secure. The RNG is salted with the text of the current command line invocation. In addition, a user may specify a seed (reproducible builds). In clang, the seed can be set via -frandom-seed=X In the back end, the seed can be set via -rng-seed=X This is the llvm part of the patch. clang part: D3391 Reviewers: ahomescu, rinon, nicholas, jfb Reviewed By: jfb Subscribers: jfb, perl Differential Revision: http://reviews.llvm.org/D3390 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211145 91177308-0d34-0410-b5e6-96231b3b80d8

* Allow X86FastIsel to cope with 64 bit absolute relocationsLouis Gerbarg2014-06-17
| | | | | | | | | | | | This patch is a follow up to r211040 & r211052. Rather than bailing out of fast isel this patch will generate an alternate instruction (movabsq) instead of the leaq. While this will always have enough room to handle the 64 bit displacment it is generally over kill for internal symbols (most displacements will be within 32 bits) but since we have no way of communicating the code model to the the assmebler in order to avoid flagging an absolute leal/leaq as illegal when using a symbolic displacement. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211130 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove more occurrences of the unused-mutex-parameter pattern.Zachary Turner2014-06-17
| | | | | | | | | | | | | | | | This pattern loses some of its usefulness when the mutex type is statically polymorphic as opposed to runtime polymorphic, as swapping out the mutex type requires changing a significant number of function parameters, and templatizing the function parameter requires the methods to be defined in the headers. Furthermore, if LLVM is compiled with threads disabled then there may even be no mutex to acquire anyway, so it should not be up to individual APIs to know whether or not acquiring a mutex is required to use those APIs to begin with. It should be up to the user of the API. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211125 91177308-0d34-0410-b5e6-96231b3b80d8

This change makes MSan take this into account in the case of multiplication by a compile-time constant. We don't handle the general, non-constant, case because (a) it's not going to be cheap (computation-wise); (b) multiplication by a partially uninitialized value in user code is a bad idea anyway. Constant case must be handled because it appears from LLVM optimization of a completely valid user code, as the test case in compiler-rt demonstrates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211092 91177308-0d34-0410-b5e6-96231b3b80d8
