2020-05-31Clarify errors and warnings about the transition to the new asm!Amanieu d'Antras-6/+12
2020-05-30Rollup merge of #72625 - Amanieu:asm-srcloc, r=petrochenkovRalf Jung-0/+115
Improve inline asm error diagnostics Previously we were just using the raw LLVM error output (with line, caret, etc) as the diagnostic message, which ends up looking rather out of place with our existing diagnostics. The new diagnostics properly format the diagnostics and also take advantage of LLVM's per-line `srcloc` attribute to map an error in inline assembly directly to the relevant line of source code. Incidentally also fixes #71639 by disabling `srcloc` metadata during LTO builds since we don't know what crate it might have come from. We can only resolve `srcloc`s from the currently crate since it indexes into the source map for the current crate. Fixes #72664 Fixes #71639 r? @petrochenkov ### Old style ```rust #![feature(llvm_asm)] fn main() { unsafe { let _x: i32; llvm_asm!( "mov $0, $1 invalid_instruction $0, $1 mov $0, $1" : "=&r" (_x) : "r" (0) :: "intel" ); } } ``` ``` error: <inline asm>:3:14: error: invalid instruction mnemonic 'invalid_instruction' invalid_instruction ecx, eax ^~~~~~~~~~~~~~~~~~~ --> src/main.rs:6:9 | 6 | / llvm_asm!( 7 | | "mov $0, $1 8 | | invalid_instruction $0, $1 9 | | mov $0, $1" ... | 12 | | :: "intel" 13 | | ); | |__________^ ``` ### New style ```rust #![feature(asm)] fn main() { unsafe { asm!( "mov {0}, {1} invalid_instruction {0}, {1} mov {0}, {1}", out(reg) _, in(reg) 0i64, ); } } ``` ``` error: invalid instruction mnemonic 'invalid_instruction' --> test.rs:7:14 | 7 | invalid_instruction {0}, {1} | ^ | note: instantiated into assembly here --> <inline asm>:3:14 | 3 | invalid_instruction rax, rcx | ^^^^^^^^^^^^^^^^^^^ ```

2019-01-02make `panictry!` private to libsyntaxAndy Russell-0/+83
This commit completely removes usage of the `panictry!` macro from outside libsyntax. The macro causes parse errors to be fatal, so using it in libsyntax_ext caused parse failures *within* a syntax extension to be fatal, which is probably not intended. Furthermore, this commit adds spans to diagnostics emitted by empty extensions if they were missing, à la #56491.

2018-11-07Removed `#[rustc_error]` from tests that are all `// compile-pass`.Felix S. Klock II-18/+4
I also added `// skip-codegen` to each one, to address potential concerns that this change would otherwise slow down our test suite spending time generating code for files that are really just meant to be checks of compiler diagnostics. (However, I will say: My preference is to not use `// skip-codegen` if one can avoid it. We can use all the testing of how we drive LLVM that we can get...) (Updated post rebase.)
