2
3SPIR-V Assember for WebGPU. The SPIR-V Assembler is a JavaScript library to
4convert SPIR-V assembly (as produced by spirv-dis in SPIR-V Tools) into a
5SPIR-V binary. The assembler assumes it is generating WebGPU SPIR-V and thus has
6the following limitations.
7
8 * Only 32 bit integers and floats supported
9 * Only GLSL accepted as an extended instruction set
10 * Doesn't support ! syntax for integers
11 * Doesn't support hex encoding for float
12
13```shell
14yarn install
15yarn test
16```
17
18You can also use `yarn watch` to watch all of the files and re-run tests as
19needed.
20
21## Webserver
22Using `yarn serve` will start a webserver on localhost:5000. If you load the
23`tests/index.html` file this will load the SVA files into browser.
24
25## Command Line
26There is a simple assembler binary with can be executed from the command line.
27
28```shell
29yarn sva tests/simple.spv_asm
30```
31
32The above will generate a `o.sva` file in the current directory.
33
34## Update spirv.data.json
35
36If there is a new spirv-headers release update the externals folder checkout
37and then:
38
39```shell
40./tools/process_grammar.rb > src/spirv.data.json
41```
