* Validate unique local names, and use validation in wasm2js. Fixes #1885 (#1886)Alon Zakai2019-01-231-1/+9
| | | | | * Also fixes some bugs in wasm2js tests that did not validate. * Rename FeatureOptions => ToolOptions, as they now contain all the basic stuff each tool needs for commandline options (validation yes or no, and which features if so).
* Wasm2js error handling improvement (#1807)Alon Zakai2018-12-061-22/+24
| | | Move the code around so the assertions are not caught in the big try-catch that reports errors as parsing errors.
* Rename `wasm2asm` to `wasm2js`, emit ESM by default (#1642)Alex Crichton2018-08-301-0/+122
* Rename the `wasm2asm` tool to `wasm2js` This commit performs a relatively simple rename of the `wasm2asm` tool to `wasm2js`. The functionality of the tool doesn't change just yet but it's intended that we'll start generating an ES module instead of just an `asm.js` function soon. * wasm2js: Support `*.wasm` input files Previously `wasm2js` only supported `*.wast` files but to make it a bit easier to use in tooling pipelines this commit adds support for reading in a `*.wasm` file directly. Determining which parser to use depends on the input filename, where the binary parser is used with `*.wasm` files and the wast parser is used for all other files. * wasm2js: Emit ESM imports/exports by default This commit alters the default behavior of `wasm2js` to emit an ESM by default, either importing items from the environment or exporting. Items like initialization of memory are also handled here.
