They both reversed the direction of the check, in a way that mostly cancelled each other out. Of course they're still mostly unimplemented, but it's better if they're not wrong.
This is important as golden test output and to verify that the output is correct. Later improvements and bug fixes are clearly visible in the IR, and unintentional changes will also be immediately spotted.
This is required for correctly differentiating between interface types.
This commit adds a new transform that converts reflect Implements() calls to runtime.interfaceImplements. At the moment, the Implements() method is not yet implemented (how ironic) but if the value passed to Implements is known at compile time the method call can be optimized to runtime.interfaceImplements to make it a regular interface assert. This commit is the last change necessary to add basic support for the encoding/json package. The json package is certainly not yet fully supported, but some trivial objects can be converted to JSON.

Still much to be done, but a most impressive step forward, and with the unit tests to prove it. Good work @aykevl Now merging. |

Does tinygo support the use of encoding/json for unmarshalling json formatted data into the basic go types (besides custom structs) now? |

This PR adds initial support for the encoding/json package. It is far from complete (structs don't work yet, for example) but it seems to actually work for encoding some trivial types.
