* [ORC] Rename VSO to JITDylib.Lang Hames2018-08-171-7/+8
| | | | | | | | | | | | | VSO was a little close to VDSO (an acronym on Linux for Virtual Dynamic Shared Object) for comfort. It also risks giving the impression that instances of this class could be shared between ExecutionSessions, which they can not. JITDylib seems moderately less confusing, while still hinting at how this class is intended to be used, i.e. as a JIT-compiled stand-in for a dynamic library (code that would have been a dynamic library if you had wanted to compile it ahead of time). llvm-svn: 340084
* [ORC] Don't call isa<> on a null value.Lang Hames2018-06-261-1/+1
| | | | | | This should fix the recent builder failures in the test-global-ctors.ll testcase. llvm-svn: 335680

* [ORC] Add LLJIT and LLLazyJIT, and replace OrcLazyJIT in LLI with LLLazyJIT.Lang Hames2018-06-261-3/+147
| | | | | | | | | | | | | | | | | | | LLJIT is a prefabricated ORC based JIT class that is meant to be the go-to replacement for MCJIT. Unlike OrcMCJITReplacement (which will continue to be supported) it is not API or bug-for-bug compatible, but targets the same use cases: Simple, non-lazy compilation and execution of LLVM IR. LLLazyJIT extends LLJIT with support for function-at-a-time lazy compilation, similar to what was provided by LLVM's original (now long deprecated) JIT APIs. This commit also contains some simple utility classes (CtorDtorRunner2, LocalCXXRuntimeOverrides2, JITTargetMachineBuilder) to support LLJIT and LLLazyJIT. Both of these classes are works in progress. Feedback from JIT clients is very welcome! llvm-svn: 335670
* [ORC] Re-apply r327566 with a fix for test-global-ctors.ll.Lang Hames2018-03-151-1/+1

* [Orc] Add support classes for inspecting and running C++ static ctor/dtors, andLang Hames2015-04-021-0/+102
use these to add support for C++ static ctors/dtors to the Orc-lazy JIT in LLI. Replace the trivial_retval_1 regression test - the new 'hello' test is covering strictly more code. llvm-svn: 233885
