| # SVA | |
| SPIR-V Assembler for WebGPU. The SPIR-V Assembler is a JavaScript library to | |
| convert SPIR-V assembly (as produced by spirv-dis in SPIR-V Tools) into a | |
| SPIR-V binary. The assembler assumes it is generating WebGPU SPIR-V and thus has | |
| the following limitations. | |
| * Only 32 bit integers and floats supported | |
| * Only GLSL accepted as an extended instruction set | |
| * Doesn't support ! syntax for integers | |
| * Doesn't support hex encoding for float | |
| ```shell | |
| yarn install | |
| yarn test | |
| ``` | |
| You can also use `yarn watch` to watch all of the files and re-run tests as | |
| needed. | |
| ## Webserver | |
| Using `yarn serve` will start a webserver on localhost:5000. If you load the | |
| `tests/index.html` file this will load the SVA files into browser. | |
| ## Command Line | |
| There is a simple assembler binary with can be executed from the command line. | |
| ```shell | |
| yarn sva tests/simple.spv_asm | |
| ``` | |
| The above will generate a `o.sva` file in the current directory. | |
| ## Update spirv.data.json | |
| If there is a new spirv-headers release update the externals folder checkout | |
| and then: | |
| ```shell | |
| ./tools/process_grammar.rb > src/spirv.data.json | |
| ``` |
