Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 12:18:55 +00:00			`//@ run-pass`
test: Update Emscripten failures/passing All tests should now have annotation for why they're ignored on emscripten. A few tests no longer need such an annotation as well! Closes #41299 2017-10-18 01:45:42 +00:00			`//@ ignore-emscripten no no_std executables`
remove support for the #[start] attribute 2024-12-14 08:13:12 +00:00			//@ ignore-wasm different `main` convention
Ignore a spuriously failing test on asmjs Other tests are already ignored for missing `rust_begin_unwind`, let's add another. 2017-06-19 19:40:51 +00:00
Use $crate and macro reexport to reduce duplicated code Many of libstd's macros are now re-exported from libcore and libcollections. Their libstd definitions have moved to a macros_stage0 module and can disappear after the next snapshot. Where the two crates had already diverged, I took the libstd versions as they're generally newer and better-tested. See e.g. d3c831b, which was a fix to libstd's assert_eq!() that didn't make it into libcore's. Fixes #16806. 2014-09-16 02:29:47 +00:00			`#![no_std]`
