[mlir] Make code blocks more consistent

2019-12-31T17:54:16+00:00

Use the same form specification for the same type of code.

Adjust License.txt file to use the LLVM license

NFC: Remove unnecessary 'llvm::' prefix from uses of llvm symbols declared in `mlir` namespace.

2019-12-18T17:29:20+00:00

Aside from being cleaner, this also makes the codebase more consistent. PiperOrigin-RevId: 286206974

mlir-translate: support -verify-diagnostics

2019-11-07T19:42:46+00:00

MLIR translation tools can emit diagnostics and we want to be able to check if it is indeed the case in tests. Reuse the source manager error handlers provided for mlir-opt to support the verification in mlir-translate. This requires us to change the signature of the functions that are registered to translate sources to MLIR: it now takes a source manager instead of a memory buffer. PiperOrigin-RevId: 279132972

Drop MemRefUtils from the ExecutionEngine

2019-10-23T14:43:06+00:00

The ExecutionEngine was updated recently to only take the LLVM dialect as input. Memrefs are no longer expected in the signature of the entry point function by the executor so there is no need to allocate and free them. The code in MemRefUtils is therefore dead and furthermore out of sync with the recent evolution of memref type to support strides. Drop it. PiperOrigin-RevId: 276272302

Add missing include to llvm Allocator.h

2019-10-19T19:11:01+00:00

This header is not self-contained otherwise. PiperOrigin-RevId: 275651582

Use llvm.func to define functions with wrapped LLVM IR function type

2019-10-10T08:34:06+00:00

This function-like operation allows one to define functions that have wrapped LLVM IR function type, in particular variadic functions. The operation was added in parallel to the existing lowering flow, this commit only switches the flow to use it. Using a custom function type makes the LLVM IR dialect type system more consistent and avoids complex conversion rules for functions that previously had to use the built-in function type instead of a wrapped LLVM IR dialect type and perform conversions during the analysis.

Add Instance Specific Pass Options.

2019-10-09T01:23:43+00:00

This allows individual passes to define options structs and for these options to be parsed per instance of the pass while building the pass pipeline from the command line provided textual specification. The user can specify these per-instance pipeline options like so: ``` struct MyPassOptions : public PassOptions { Option exampleOption{*this, "flag-name", llvm::cl::desc("...")}; List exampleListOption{*this, "list-flag-name", llvm::cl::desc("...")}; }; static PassRegistration pass("my-pass", "description"); ``` PiperOrigin-RevId: 273650140

Fix JitRunner.cpp Error creation pattern and reactivate tests.

2019-09-27T16:56:40+00:00

linalg_integration_test.mlir and simple.mlir were temporarily disabled due to an OSS-only failure. The issue is that, once created, an llvm::Error must be explicitly checked before it can be discarded or overwritten. This CL fixes the issue and reenable the test. PiperOrigin-RevId: 271589651

Drop support for memrefs from JitRunner

2019-09-26T12:42:01+00:00

The support for functions taking and returning memrefs of floats was introduced in the first version of the runner, created before MLIR had reliable lowering of allocation/deallocation to library calls. It forcibly runs MLIR transformation convering affine, loop and standard dialects into the LLVM dialect, unlike the other runner flows that accept the LLVM dialect directly. Memref support leads to more complex layering and is generally fragile. Drop it in favor of functions returning a scalar, or library-based function calls to print memrefs and other data structures.
