Till [1] `rust-analyzer` used to guess the `sysroot` based on the `sysroot_src` at [2]. Now `sysroot` is a required parameter for a `rust-project.json` file. It is required because `rust-analyzer` need it to find the proc-macro server [3]. In the current version of `rust-analyzer` the `sysroot_src` is only used to include the inbuilt library crates (std, core, alloc, etc) [4]. Since we already specify the core library to be included in the `rust-project.json` we don't need to define the `sysroot_src`. Code editors like VS Code try to use the latest version of rust-analyzer (which is updated every week) instead of the version of rust-analyzer that comes with the rustup toolchain (which is updated every six weeks along with the rust version). Without this change `rust-analyzer` is breaking for anyone using VS Code. As they are getting the latest version of `rust-analyzer` with the changes made in [1]. `rust-analyzer` will also start breaking for other developers as they update their rust version (assuming that also updates the rust-analyzer version on their system). This patch should work with every setup as there is no more guess work being done by `rust-analyzer`. [ Lukas, who leads the rust-analyzer team, says: `sysroot_src` is required now if you want to have the sysroot source libraries be loaded. I think we used to infer it as `{sysroot}/lib/rustlib/src/rust/library` before when only the `sysroot` field was given but that was since changed to make it possible in having a sysroot without the standard library sources (that is only have the binaries available). So if you want the library sources to be loaded by rust-analyzer you will have to set that field as well now. - Miguel ] Link: https://github.com/rust-lang/rust-analyzer/pull/17287 [1] Link: https://github.com/rust-lang/rust-analyzer/blob/f372a8a1176ff8dd5f45ab2ddd45f3530db0374f/crates/project-model/src/workspace.rs#L367-L374 [2] Link: https://github.com/rust-lang/rust-analyzer/blob/eeb192b79aeac47b40add66347022af17a74fbaf/crates/project-model/src/sysroot.rs#L180-L192 [3] Link: https://github.com/search?q=repo%3AVeykril%2Frust-analyzer%20src_root()&type=code [4] Tested-by: Dirk Behme Signed-off-by: Sarthak Singh Link: https://rust-for-linux.zulipchat.com/#narrow/stream/291565-Help/topic/How.20to.20rust-analyzer.20correctly.20working Link: https://lore.kernel.org/r/20240724172713.899399-1-sarthak.singh99@gmail.com [ Formatted comment, fixed typo and removed spurious empty line. - Miguel ] Signed-off-by: Miguel Ojeda --- rust/Makefile | 2 +- scripts/generate_rust_analyzer.py | 6 +++++- 2 files changed, 6 insertions(+), 2 deletions(-) (limited to 'scripts') diff --git a/rust/Makefile b/rust/Makefile index 1f10f92737f2..6c0644b6090c 100644 --- a/rust/Makefile +++ b/rust/Makefile @@ -350,7 +350,7 @@ rust-analyzer: $(Q)$(srctree)/scripts/generate_rust_analyzer.py \ --cfgs='core=$(core-cfgs)' --cfgs='alloc=$(alloc-cfgs)' \ $(realpath $(srctree)) $(realpath $(objtree)) \ - $(RUST_LIB_SRC) $(KBUILD_EXTMOD) > \ + $(rustc_sysroot) $(RUST_LIB_SRC) $(KBUILD_EXTMOD) > \ $(if $(KBUILD_EXTMOD),$(extmod_prefix),$(objtree))/rust-project.json redirect-intrinsics = \ diff --git a/scripts/generate_rust_analyzer.py b/scripts/generate_rust_analyzer.py index f270c7b0cf34..d2bc63cde8c6 100755 --- a/scripts/generate_rust_analyzer.py +++ b/scripts/generate_rust_analyzer.py @@ -145,6 +145,7 @@ def main(): parser.add_argument('--cfgs', action='append', default=[]) parser.add_argument("srctree", type=pathlib.Path) parser.add_argument("objtree", type=pathlib.Path) + parser.add_argument("sysroot", type=pathlib.Path) parser.add_argument("sysroot_src", type=pathlib.Path) parser.add_argument("exttree", type=pathlib.Path, nargs="?") args = parser.parse_args() @@ -154,9 +155,12 @@ def main(): level=logging.INFO if args.verbose else logging.WARNING ) + # Making sure that the `sysroot` and `sysroot_src` belong to the same toolchain. + assert args.sysroot in args.sysroot_src.parents + rust_project = { "crates": generate_crates(args.srctree, args.objtree, args.sysroot_src, args.exttree, args.cfgs), - "sysroot_src": str(args.sysroot_src), + "sysroot": str(args.sysroot), } json.dump(rust_project, sys.stdout, sort_keys=True, indent=4) -- cgit v1.2.3 From 0eba65f0310d3c7d5516c7fd4c172d0bfa8b285b Mon Sep 17 00:00:00 2001 From: Miguel Ojeda Date: Tue, 6 Aug 2024 16:45:58 +0200 Subject: rust: x86: remove `-3dnow{,a}` from target features LLVM 19 is dropping support for 3DNow! in commit f0eb5587ceeb ("Remove support for 3DNow!, both intrinsics and builtins. (#96246)"): Remove support for 3DNow!, both intrinsics and builtins. (#96246) This set of instructions was only supported by AMD chips starting in the K6-2 (introduced 1998), and before the "Bulldozer" family (2011). They were never much used, as they were effectively superseded by the more-widely-implemented SSE (first implemented on the AMD side in Athlon XP in 2001). This is being done as a predecessor towards general removal of MMX register usage. Since there is almost no usage of the 3DNow! intrinsics, and no modern hardware even implements them, simple removal seems like the best option. Thus we should avoid passing these to the backend, since otherwise we get a diagnostic about it: '-3dnow' is not a recognized feature for this target (ignoring feature) '-3dnowa' is not a recognized feature for this target (ignoring feature) We could try to disable them only up to LLVM 19 (not the C side one, but the one used by `rustc`, which may be built with a range of LLVMs). However, to avoid more complexity, we can likely just remove them altogether. According to Nikita [2]: > I don't think it's needed because LLVM should not generate 3dnow > instructions unless specifically asked to, using intrinsics that > Rust does not provide in the first place. Thus do so, like Rust did for one of their builtin targets [3]. For those curious: Clang will warn only about trying to enable them (`-m3dnow{,a}`), but not about disabling them (`-mno-3dnow{,a}`), so there is no change needed there.
