[ORC] Add support for emulated TLS to ORCv2.

2020-01-29T20:50:16+00:00

This commit adds a ManglingOptions struct to IRMaterializationUnit, and replaces IRCompileLayer::CompileFunction with a new IRCompileLayer::IRCompiler class. The ManglingOptions struct defines the emulated-TLS state (via a bool member, EmulatedTLS, which is true if emulated-TLS is enabled and false otherwise). The IRCompileLayer::IRCompiler class wraps an IRCompiler (the same way that the CompileFunction typedef used to), but adds a method to return the IRCompileLayer::ManglingOptions that the compiler will use. These changes allow us to correctly determine the symbols that will be produced when a thread local global variable defined at the IR level is compiled with or without emulated TLS. This is required for ORCv2, where MaterializationUnits must declare their interface up-front. Most ORCv2 clients should not require any changes. Clients writing custom IR compilers will need to wrap their compiler in an IRCompileLayer::IRCompiler, rather than an IRCompileLayer::CompileFunction, however this should be a straightforward change (see modifications to CompileUtils.* in this patch for an example).

[ORC] Fix argv handling in runAsMain / lli.

2020-01-11T21:03:38+00:00

This fixes an off-by-one error in the argc value computed by runAsMain, and switches lli back to using the input bitcode (rather than the string "lli") as the effective program name. Thanks to Stefan Graenitz for spotting the bug.

[ORC] Refactor definition-generation, add a generator for static libraries.

2019-08-13T16:05:18+00:00

This patch replaces the JITDylib::DefinitionGenerator typedef with a class of the same name, and adds support for attaching a sequence of DefinitionGeneration objects to a JITDylib. This patch also adds a new definition generator, StaticLibraryDefinitionGenerator, that can be used to add symbols fom a static library to a JITDylib. An object from the static library will be added (via a supplied ObjectLayer reference) whenever a symbol from that object is referenced. To enable testing, lli is updated to add support for the --extra-archive option when running in -jit-kind=orc-lazy mode. llvm-svn: 368707

[ORC] Re-apply r345077 with fixes to remove ambiguity in lookup calls.

Revert r345077 "[ORC] Change how non-exported symbols are matched during lookup."

2018-10-23T20:54:43+00:00

Doesn't build on Windows. The call to 'lookup' is ambiguous. Clang and MSVC agree, anyway. http://lab.llvm.org:8011/builders/clang-x64-windows-msvc/builds/787 C:\b\slave\clang-x64-windows-msvc\build\llvm.src\unittests\ExecutionEngine\Orc\CoreAPIsTest.cpp(315): error C2668: 'llvm::orc::ExecutionSession::lookup': ambiguous call to overloaded function C:\b\slave\clang-x64-windows-msvc\build\llvm.src\include\llvm/ExecutionEngine/Orc/Core.h(823): note: could be 'llvm::Expected llvm::orc::ExecutionSession::lookup(llvm::ArrayRef,llvm::orc::SymbolStringPtr)' C:\b\slave\clang-x64-windows-msvc\build\llvm.src\include\llvm/ExecutionEngine/Orc/Core.h(817): note: or 'llvm::Expected llvm::orc::ExecutionSession::lookup(const llvm::orc::JITDylibSearchList &,llvm::orc::SymbolStringPtr)' C:\b\slave\clang-x64-windows-msvc\build\llvm.src\unittests\ExecutionEngine\Orc\CoreAPIsTest.cpp(315): note: while trying to match the argument list '(initializer list, llvm::orc::SymbolStringPtr)' llvm-svn: 345078

[ORC] Change how non-exported symbols are matched during lookup.

2018-10-23T20:20:22+00:00

In the new scheme the client passes a list of (JITDylib&, bool) pairs, rather than a list of JITDylibs. For each JITDylib the boolean indicates whether or not to match against non-exported symbols (true means that they should be found, false means that they should not). The MatchNonExportedInJD and MatchNonExported parameters on lookup are removed. The new scheme is more flexible, and easier to understand. This patch also updates JITDylib search orders to be lists of (JITDylib&, bool) pairs to match the new lookup scheme. Error handling is also plumbed through the LLJIT class to allow regression tests to fail predictably when a lookup from a lazy call-through fails. llvm-svn: 345077

[ORC] Add some more basic sanity tests for the LLJIT.

2018-10-20T20:39:53+00:00

minimal.ll contains a main function that returns zero, and single-function-call.ll contains a main function that calls a foo function that returns zero. These minimal tests can help to rule out some trivial JIT bugs when other tests fail. This commit also renames hello.ll to global-ctors-and-dtors.ll, which better reflects what it is actually testing. llvm-svn: 344863

[ORC] Add partitioning support to CompileOnDemandLayer2.

2018-09-29T23:49:57+00:00

CompileOnDemandLayer2 now supports user-supplied partition functions (the original CompileOnDemandLayer already supported these). Partition functions are called with the list of requested global values (i.e. global values that currently have queries waiting on them) and have an opportunity to select extra global values to materialize at the same time. Also adds testing infrastructure for the new feature to lli. llvm-svn: 343396

Reapply r343058 with a fix for -DLLVM_ENABLE_THREADS=OFF.

2018-09-26T16:26:59+00:00

Modifies lit to add a 'thread_support' feature that can be used in lit test REQUIRES clauses. The thread_support flag is set if -DLLVM_ENABLE_THREADS=ON and unset if -DLLVM_ENABLE_THREADS=OFF. The lit flag is used to disable the multiple-compile-threads-basic.ll testcase when threading is disabled. llvm-svn: 343122

Revert r343058 "[ORC] Add support for multithreaded compiles to LLJIT and LLLazyJIT."

2018-09-26T12:15:23+00:00

This doesn't work well in builds configured with LLVM_ENABLE_THREADS=OFF, causing the following assert when running ExecutionEngine/OrcLazy/multiple-compile-threads-basic.ll: lib/ExecutionEngine/Orc/Core.cpp:1748: Expected llvm::orc::lookup(const llvm::orc::JITDylibList &, llvm::orc::SymbolStringPtr): Assertion `ResultMap->size() == 1 && "Unexpected number of results"' failed. > LLJIT and LLLazyJIT can now be constructed with an optional NumCompileThreads > arguments.
