Adds a -Z flag to control the file path that the Gcov gcda output is written to during runtime. This flag expects a path and filename, e.g. -Z profile-emit=gcov/out/lib.gcda. This works similar to GCC/Clang's -fprofile-dir flag which allows control over the output path for gcda coverage files.
`compiletest` and `remote-test-client`: The command line for `remote-test-client` was changed slightly to allow cross-platform compatible paths. The old way of supplying the support libs was by joining their paths with the executable path with `:`. This caused Windows-style paths to be split after the directory letter. Now, the number of support libs is provided as a parameter as well, and the support lib paths are split off from the regular args in the client. `remote-test-server`: - Marked Unix-only parts as such and implemented Windows alternatives - On Windows `LD_LIBRARY_PATH` doesn't exist. Libraries are loaded from `PATH` though, so that's the way around it. - Tiny cleanup: `Command::args`/`envs` instead of manually looping over them - The temp path for Windows has to be set via environment variable, since there isn't a global temp directory that would work on every machine (as a static string)
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 rust-lang#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 rust-lang#72664 Fixes rust-lang#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 | ^^^^^^^^^^^^^^^^^^^ ```
expand `env!` with def-site context Similar to rust-lang#66349. Fixes rust-lang/rust-clippy#5619.
…ewjasper Allow types (with lifetimes/generics) in impl_lint_pass cc rust-lang/rust-clippy#5279 (comment) This allows to implement `LintPass` for types with lifetimes and/or generics. The only thing, I'm not sure of is the `LintPass::name` function, which now includes the lifetime(s) (which will be `'_` most of the time) in the name returned for the lint pass, if it exists. But I don't think that this should be a problem, since the `LintPass::name` is never used for output for the user (?).
…wjasper Add -Z profile-emit=<path> for Gcov gcda output. Adds a -Z flag to control the file path that the Gcov gcda output is written to during runtime. This flag expects a path and filename, e.g. -Z profile-emit=gcov/out/lib.gcda. This works similar to GCC/Clang's -fprofile-dir flag which allows control over the output path for gcda coverage files.
…crum rustc_session: Cleanup session creation Noticed while reviewing rust-lang#72618.
…rk-Simulacrum Make remote-test-client and remote-test-server compatible with windows `compiletest` and `remote-test-client`: The command line for `remote-test-client` was changed slightly to allow cross-platform compatible paths. The old way of supplying the support libs was by joining their paths with the executable path with `:`. This caused Windows-style paths to be split after the directory letter. Now, the number of support libs is provided as a parameter as well, and the support lib paths are split off from the regular args in the client. `remote-test-server`: - Marked Unix-only parts as such and implemented Windows alternatives - On Windows `LD_LIBRARY_PATH` doesn't exist.

Make bootstrap aware of relative libdir in stage0 compiler Follows up rust-lang#72692 Fixes rust-lang#72661
rustc_lexer: Optimize shebang detection slightly Sorry, I just couldn't resist. It shouldn't make any difference in practice. Also, documented a previously unnoticed case with doc comments treated as regular comments during shebang detection.
miri validation: clarify valid values of 'char' The old text said "expected a valid unicode codepoint", which is not actually correct -- it has to be a scalar value (which is a code point that is not part of a surrogate pair).
…f-id-from-node-id, r=petrochenkov rustdoc: remove calls to `local_def_id_from_node_id` rustdoc calls `local_def_id_from_node_id(CRATE_NODE_ID)` when it can just creates a top level `DefId` using `DefId::local(CRATE_DEF_INDEX)`. cc rust-lang#50928 r? @petrochenkov
