[AUTO-GENERATED] Migrate ui tests from `//` to `//@` directives 2024-02-16 20:02:50 +00:00			`//@ run-pass`
ci: Disable optimized tests for asm.js Since all tests are compiled with LTO effectively in Emscripten this commit disables optimizations to hopefully squeeze some more time out of the CI builders. Closes #48826 2018-03-16 18:42:42 +00:00
remove most `simd_` intrinsic declaration in tests instead, we can just import the intrinsics from core 2025-02-24 16:26:56 +00:00			`#![feature(repr_simd, core_intrinsics)]`
Add tests for issues with the E-needstest label 2017-07-25 02:31:59 +00:00
