* This won't work for most people until some upstream changes percolate.
* Sequestered it behind a flag and a special configure script (cmake_configure_iree.sh) for now.
* Adds a new to_boolean op to evaluate a value as a truthy i1
* Uses cascading scf.if ops to properly evaluate and/or sequences (short-circuit and original value returning)
* Adds a helper to construct select ops and uses it to implement 'not'
* Makes the OpBuilder an input to the DialectHelper.
* The containment hierarchy can be simplified further.
* There are still only a few places this is instantiated, so opting for working over great.
* Got side-tracked hunting down a vague-linkage RTTI issue due to not anchoring key methods in PassOptions.h to a module.
* Took the path of least resistance and just added the option to build LLVM with RTTI. I know how to fix this but would like to do some broader upstream fixes versus just hunting/pecking/working around in this project.
The secret here is LLVM_ENABLE_WARNINGS=ON.
I also fixed a couple warnings, which gets us to be warning-clean.
I noticed also that npcomp-run-mlir/basic.mlir seems to be failing.
Maybe something since the latest integrate. My next commit (introduce
npcomp mini runtime) will largely rewrite it though, so it'll get fixed
then.
This script (make sure to `source` it!) defines a number of handy
aliases which make compiler development more convenient.
Please feel free to add anything you find useful here.
The code isn't super clean, but is a useful incremental step
establishing most of the boilerplate for future enhancements.
We can't print or return tensors yet so correctness TBD, but I've
stepped into the running code in the debugger so I know it definitely is
running.
This is the first step to building out an npcomp mini-runtime. The
mini-runtime doesn't have to be fancy or complex, but it should at least
be layered nicely (which this code and the current compiler interaction
with the "runtime" code is not). Now that we have boilerplate for e2e
execution in some form, we can build that out.
With this commit, we finish conversion to LLVM dialect, and should be
ready for subsequent commits to convert to an LLVM module and let LLVM
codegen to native machine code.
This required a custom "lower to LLVM" pass to support lowering
tcp.abort_if to a runtime call. In the future, this pass will grow to do
type conversions for our own runtime types as we add those.
