Emit DW_AT_main_subprogram This changes rustc to emit DW_AT_main_subprogram on the "main" program. This lets gdb suitably stop at the user's main in response to "start" (rather than the library's main, which is what happens currently). Fixes #32620 r? michaelwoerister 2016-11-30 21:59:45 +00:00			`//@ ignore-windows`

Update test directives for `wasm32-wasip1` * The WASI targets deal with the `main` symbol a bit differently than native so some `codegen` and `assembly` tests have been ignored. * All `ignore-emscripten` directives have been updated to `ignore-wasm32` to be more clear that all wasm targets are ignored and it's not just Emscripten. * Most `ignore-wasm32-bare` directives are now gone. * Some ignore directives for wasm were switched to `needs-unwind` instead. * Many `ignore-wasm32*` directives are removed as the tests work with WASI as opposed to `wasm32-unknown-unknown`. 2024-03-06 20:44:54 +00:00			`//@ ignore-wasi wasi codegens the main symbol differently`
