Working on compiler IR is a daunting task. I have therefore added a new system property `enso.compiler.dumpIr` that will help with that. It dumps the encountered IRs to `ir-dumps` directory in the [GraphViz](www.graphviz.org) format. More info in updated docs. Note that all the functionality to dump IRs to `dot` files was already implemented. This PR just adds the command line option and updates docs. # Important Notes - `--dump-graphs` cmd line option is removed as per [Jaroslav's request](https://github.com/enso-org/enso/pull/10740#pullrequestreview-2216676140). - To dump graphs, use `-Dgraal.Dump=Truffle:2` system property passed via `JAVA_OPTS` env var. If you run `env JAVA_OPTS='-Denso.compiler.dumpIr=true' enso --run tmp.enso` where `tmp.enso` is, e.g.: ``` from Standard.Base import all main = 42 ``` You will then have something like: ``` $ ls ir-dumps Standard.Base.Data.Filter_Condition.dot Standard.Base.Data.Time.dot Standard.Base.System.Advanced.dot Standard.Base.Warning.dot Standard.Base.Data.Locale.dot Standard.Base.Enso_Cloud.Enso_File.dot Standard.Base.System.File.Advanced.dot tmp.dot Standard.Base.Data.Numeric.dot Standard.Base.Errors.dot Standard.Base.System.File.dot Standard.Base.Data.Numeric.Internal.dot Standard.Base.Network.HTTP.Internal.dot Standard.Base.System.File.Generic.dot Standard.Base.Data.Text.Regex.Internal.dot Standard.Base.Runtime.dot Standard.Base.System.Internal.dot ``` You can then visualize any of these with `dot -Tsvg -O ir-dumps/tmp.dot`. An example how that could look like is

# Enso Runtime
|
|
|
|
The Enso runtime refers to both the compiler and the optimising JIT runtime for
|
|
Enso. While this might seem like a strange choice, it makes sense internally as
|
|
the components are integrated to a level not seen in most languages. It
|
|
encompasses the following functionality:
|
|
|
|
- **Parsing:** Taking Enso code as input and generating an AST that maintains a
|
|
sophisticated set of information about the input.
|
|
- **Desugaring:** Reducing the user-facing Enso code into a simplified language
|
|
known as `Core`.
|
|
- **Type Inference:** Inferring the types of bindings in the user's code.
|
|
- **Type Checking:** Checking that the inferred and provided types for bindings
|
|
match up across the codebase.
|
|
- **Optimisation:** Static optimisation processes to improve the performance of
|
|
the user's program.
|
|
- **Code Execution:** Actually running the Enso code.
|
|
- **Introspection Hooks:** Providing hooks into the running code to allow the
|
|
language server to inspect information about the code as it runs.
|
|
|
|
This folder contains all of the documentation related to the runtime, which is
|
|
broken up as follows:
|
|
|
|
- [**Caching:**](./caching.md) A description of the runtime's value caching
|
|
mechanism.
|
|
- [**Demand Analysis:**](./demand-analysis.md) A specification for the demand
|
|
analysis process in the Enso compiler that assists users with working with
|
|
suspended computations.
|
|
- [**Function Calling Flow:**](./function-call-flow.md) A description of the
|
|
involved logic that goes into a calling a function performantly in the Enso
|
|
runtime, while also supporting the flexible function syntax.
|
|
- [**Runtime Features:**](./runtime-features.md) A description of (and plan for)
|
|
the features of the Enso runtime.
|
|
- [**Unbounded Recursion:**](./unbounded-recursion.md) An exploration of
|
|
techniques for achieving unbounded recursion on the JVM.
|
|
- [**Instruments:**](./instruments.md) A description of instrumentation in the
|
|
language runtime.
|
|
- [**Execution Server Flow:**](./execution-server-flow.md) An explanation of how
|
|
the execution server orchestrates Enso's execution.
|
|
- [**Builtin Base Methods:**](./builtin-base-methods.md) An explanation of the
|
|
DSL we use for defining builtin types and methods.
|
|
- [**Searcher:**](./searcher.md) An explanation of how the searcher works.
|
|
- [**Instruments:**](./instruments.md) An explanation of how we compile Truffle
|
|
instrumentation.
|
|
- [**Compiler IR:**](./compiler-ir.md) An explanation of the Enso compiler IR.
|
|
- [**IR Caching:**](./ir-caching.md) An explanation of how we cache the compiler
|
|
IR to reduce startup times.
