* [sanitizer] [msan] Fix origin store of array typesAdhemerval Zanella2016-01-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the memory sanitizer origin store instrumentation for array types. This can be triggered by cases where frontend lowers function return to array type instead of aggregation. For instance, the C code: -- struct mypair { int64_t x; int y; }; mypair my_make_pair(int64_t x, int y) { mypair p; p.x = x; p.y = y; return p; } int foo (int p) { mypair z = my_make_pair(p, 0); return z.y + z.x; } -- It will be lowered with target set to aarch64-linux and -O0 to: -- [...] define i32 @_Z3fooi(i32 %p) #0 { [...] %call = call [2 x i64] @_Z12my_make_pairxi(i64 %conv, i32 0) %1 = bitcast %struct.mypair* %z to [2 x i64]* store [2 x i64] %call, [2 x i64]* %1, align 8 [...] -- The origin store will emit a 'icmp' to test each store value again the TLS origin array. However since 'icmp' does not support ArrayType the memory instrumentation phase will bail out with an error. This patch change it by using the same strategy used for struct type on array. It fixes the 'test/msan/insertvalue_origin.cc' for aarch64 (the -O0 case). llvm-svn: 257375

| | | | | | | | The new ORC remote-JITing support provides a superset of the old code's functionality, so we can replace the old stuff. As a bonus, a couple of previously XFAILed tests have started passing. llvm-svn: 257343

| | | | | | | In the OptimizeLEA pass keep instructions' positions in the basic block saved and use them for calculation of the distance between two instructions instead of std::distance. This reduces complexity of the pass from O(n^3) to O(n^2) and thus the compile time. Differential Revision: http://reviews.llvm.org/D15692 llvm-svn: 257328

* [Orc] Add support for remote JITing to the ORC API.Lang Hames2016-01-112-0/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds utilities to ORC for managing a remote JIT target. It consists of: 1. A very primitive RPC system for making calls over a byte-stream. See RPCChannel.h, RPCUtils.h. 2. An RPC API defined in the above system for managing memory, looking up symbols, creating stubs, etc. on a remote target. See OrcRemoteTargetRPCAPI.h. 3. An interface for creating high-level JIT components (memory managers, callback managers, stub managers, etc.) that operate over the RPC API. See OrcRemoteTargetClient.h. 4. A helper class for building servers that can handle the RPC calls. See OrcRemoteTargetServer.h. The system is designed to work neatly with the existing ORC components and functionality. In particular, the ORC callback API (and consequently the CompileOnDemandLayer) is supported, enabling lazy compilation of remote code. Assuming this doesn't trigger any builder failures, a follow-up patch will be committed which tests these utilities by using them to replace LLI's existing remote-JITing demo code. llvm-svn: 257305

| | | | | | | | This is a more generic version of the MCJITMemoryManager::notifyObjectLoaded method: It provides only a RuntimeDyld reference (rather than an ExecutionEngine), and so can be used with ORC JIT stacks. llvm-svn: 257296

* [RuntimeDyld] Add alignment arguments to the reserveAllocationSpace method ofLang Hames2016-01-103-20/+28
| | | | | | | | | | | | | | RuntimeDyld::MemoryManager. The RuntimeDyld::MemoryManager::reserveAllocationSpace method is called when object files are loaded, and gives clients a chance to pre-allocate memory for all segments. Previously only the size of each segment (code, ro-data, rw-data) was supplied but not the alignment. This hasn't caused any problems so far, as most clients allocate via the MemoryBlock interface which returns page-aligned blocks. Adding alignment arguments enables finer grained allocation while still satisfying alignment restrictions. llvm-svn: 257294
* [SectionMemoryManager] Don't just drop the RO free listKeno Fischer2016-01-101-3/+0
| | | | | | | | | | | | | In r255760, I optimized the SectionMemoryManager to make better use of virtual memory on platforms where the allocation granularity was bigger than the protection granularity. As part of this, fixing up the free list became more complicated and was moved into `applyMemoryGroupPermissions`. Unfortunately, I forgot to actually remove the call that drops the free list for RO memory (I did remove the corresponding one for RX memory), defeating the whole optimization. llvm-svn: 257293

* [JumpThreading] Don't forget to report that the IR changedDavid Majnemer2016-01-102-3/+7
| | | | | | | | | | | | | | JumpThreading's runOnFunction is supposed to return true if it made any changes. JumpThreading has a call to removeUnreachableBlocks which may result in changes to the IR but runOnFunction didn't appropriate account for this possibility, leading to badness. While we are here, make sure to call LazyValueInfo::eraseBlock in removeUnreachableBlocks; JumpThreading preserves LVI. This fixes PR26096. llvm-svn: 257279

* [WinEH] Fix catchpad pred verificationJoseph Tremoulet2016-01-101-0/+3
| | | | | | | | | | | | | | | Summary: The code was simply ensuring that the catchpad's pred is its catchswitch, which was letting cases slip through where the flow edge was the unwind edge of the catchswitch rather than one of its catch clauses.

| | | | | | | | | | | | | | | | Summary: Funclet-based EH personalities/tables likely can't handle these, and they can't be generated at source, so make them officially illegal in IR as well.

* [WinEH] Verify consistent funclet unwind exitsJoseph Tremoulet2016-01-101-22/+146
| | | | | | | | | | | | | | | | | | | | Summary: A funclet EH pad may be exited by an unwind edge, which may be a cleanupret exiting its cleanuppad, an invoke exiting a funclet, or an unwind out of a nested funclet transitively exiting its parent. Funclet EH personalities require all such exceptional exits from a given funclet to have the same unwind destination, and EH preparation / state numbering / table generation implicitly depends on this. Formalize it as a rule of the IR in the LangRef and verifier.

* [WinEH] Verify unwind edges against EH pad treeJoseph Tremoulet2016-01-101-3/+36
| | | | | | | | | | | | | | | | | | | | | | Summary: Funclet EH personalities require a tree-like nesting among funclets (enforced by the ParentPad linkage in the IR), and also require that unwind edges conform to certain rules with respect to the tree: - An unwind edge may exit 0 or more ancestor pads - An unwind edge must enter exactly one EH pad, which must be distinct from any exited pads - A cleanupret's edge must exit its cleanuppad Describe these rules in the LangRef, and enforce them in the verifier.

* [Orc][RuntimeDyld] Prevent duplicate calls to finalizeMemory on shared memoryLang Hames2016-01-091-0/+11
| | | | | | | | | | | | | | | | | | | | | | | managers. Prior to this patch, recursive finalization (where finalization of one RuntimeDyld instance triggers finalization of another instance on which the first depends) could trigger memory access failures: When the inner (dependent) RuntimeDyld instance and its memory manager are finalized, memory allocated (but not yet relocated) by the outer instance is locked, and relocation in the outer instance fails with a memory access error. This patch adds a latch to the RuntimeDyld::MemoryManager base class that is checked by a new method: RuntimeDyld::finalizeWithMemoryManagerLocking, ensuring that shared memory managers are only finalized by the outermost RuntimeDyld instance. This allows ORC clients to supply the same memory manager to multiple calls to addModuleSet. In particular it enables the use of user-supplied memory managers with the CompileOnDemandLayer which must reuse the supplied memory manager for each function that is lazily compiled. llvm-svn: 257263
