From 35196eab279340376929dd75ed717ef4830e2fa9 Mon Sep 17 00:00:00 2001 From: Leo Kettmeir Date: Thu, 16 Mar 2023 19:29:32 -0400 Subject: BREAKING(unstable): remove WebGPU (#18094) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This PR _**temporarily**_ removes WebGPU (which has behind the `--unstable` flag in Deno), due to performance complications due to its presence. It will be brought back in the future; as a point of reference, Chrome will ship WebGPU to stable on 26/04/2023. --------- Co-authored-by: Bartek Iwańczuk --- cli/tests/testdata/webgpu/computepass_shader.wgsl | 38 ----------------------- 1 file changed, 38 deletions(-) delete mode 100644 cli/tests/testdata/webgpu/computepass_shader.wgsl (limited to 'cli/tests/testdata/webgpu/computepass_shader.wgsl') diff --git a/cli/tests/testdata/webgpu/computepass_shader.wgsl b/cli/tests/testdata/webgpu/computepass_shader.wgsl deleted file mode 100644 index 41af4363a..000000000 --- a/cli/tests/testdata/webgpu/computepass_shader.wgsl +++ /dev/null @@ -1,38 +0,0 @@ -@group(0) -@binding(0) -var v_indices: array; // this is used as both input and output for convenience - -// The Collatz Conjecture states that for any integer n: -// If n is even, n = n/2 -// If n is odd, n = 3n+1 -// And repeat this process for each new n, you will always eventually reach 1. -// Though the conjecture has not been proven, no counterexample has ever been found. -// This function returns how many times this recurrence needs to be applied to reach 1. -fn collatz_iterations(n_base: u32) -> u32{ - var n: u32 = n_base; - var i: u32 = 0u; - loop { - if (n <= 1u) { - break; - } - if (n % 2u == 0u) { - n = n / 2u; - } - else { - // Overflow?
