2023-03-29Fix linker detection for clang with prefixTaiki Endo-1/+3
2023-02-24Rename many interner functions.Nicholas Nethercote-1/+1
(This is a large commit. The changes to `compiler/rustc_middle/src/ty/context.rs` are the most important ones.) The current naming scheme is a mess, with a mix of `_intern_`, `intern_` and `mk_` prefixes, with little consistency. In particular, in many cases it's easy to use an iterator interner when a (preferable) slice interner is available. The guiding principles of the new naming system: - No `_intern_` prefixes. - The `intern_` prefix is for internal operations. - The `mk_` prefix is for external operations. - For cases where there is a slice interner and an iterator interner, the former is `mk_foo` and the latter is `mk_foo_from_iter`. Also, `slice_interners!` and `direct_interners!` can now be `pub` or non-`pub`, which helps enforce the internal/external operations division. It's not perfect, but I think it's a clear improvement. The following lists show everything that was renamed. slice_interners - const_list - mk_const_list -> mk_const_list_from_iter - intern_const_list -> mk_const_list - substs - mk_substs -> mk_substs_from_iter - intern_substs -> mk_substs - check_substs -> check_and_mk_substs (this is a weird one) - canonical_var_infos - intern_canonical_var_infos -> mk_canonical_var_infos - poly_existential_predicates - mk_poly_existential_predicates -> mk_poly_existential_predicates_from_iter - intern_poly_existential_predicates -> mk_poly_existential_predicates - _intern_poly_existential_predicates -> intern_poly_existential_predicates - predicates - mk_predicates -> mk_predicates_from_iter - intern_predicates -> mk_predicates - _intern_predicates -> intern_predicates - projs - intern_projs -> mk_projs - place_elems - mk_place_elems -> mk_place_elems_from_iter - intern_place_elems -> mk_place_elems - bound_variable_kinds - mk_bound_variable_kinds -> mk_bound_variable_kinds_from_iter - intern_bound_variable_kinds -> mk_bound_variable_kinds direct_interners - region - intern_region (unchanged) - const - mk_const_internal -> intern_const - const_allocation - intern_const_alloc -> mk_const_alloc - layout - intern_layout -> mk_layout - adt_def - intern_adt_def -> mk_adt_def_from_data (unusual case, hard to avoid) - alloc_adt_def(!) -> mk_adt_def - external_constraints - intern_external_constraints -> mk_external_constraints Other - type_list - mk_type_list -> mk_type_list_from_iter - intern_type_list -> mk_type_list - tup - mk_tup -> mk_tup_from_iter - intern_tup -> mk_tup
2023-02-21Linker: use -z <params> instead of -z<params>Frank Denis-8/+8
The GNU linker accepts -z<params>, but this is undocumented, and not supported by other linkers. In particular, `zig cc`, when used as the C compiler/linker (e.g. when using `cargo-zigbuild`), will not accept this undocumented syntax. In `linker.rs`, both syntaxes are also used inconsistently. The Go compiler used to have the same issue, but fixed it: https://github.com/golang/go/commit/38607c553878da21b5042e63997ecb3b7201e684

2023-01-15Preserve split DWARF files when building archives.Kyle Huey-6/+0
The optimization that removes artifacts when building libraries is correct from the compiler's perspective but not from a debugger's perspective. Unpacked split debuginfo is referred to by filename and debuggers need the artifact that contains debuginfo to continue to exist at that path. Ironically the test expects the correct behavior but it was not running.
2023-01-14Auto merge of #106646 - Amanieu:ilp32-object, r=Mark-Simulacrumbors-1/+7
Fix aarch64-unknown-linux-gnu_ilp32 target This was broken because the synthetic object files produced by rustc were for 64-bit AArch64, which caused link failures when combined with 32-bit ILP32 object files. This PR updates the object crate to 0.30.1 which adds support for generating ILP32 AArch64 object files.

riscv: Fix ELF header flags The previous version added both `EF_RISCV_FLOAT_ABI_DOUBLE` and `EF_RISCV_RVC` if the "D" extension was enabled on riscv64 targets. riscv32 targets were not accounted for. This patch changes this so that: - Only add `EF_RISCV_RVC` if the "C" extension is enabled - Add `EF_RISCV_FLOAT_ABI_SINGLE` if the "F" extension is enabled and the "D" extension is not - Add these ELF flags for riscv32 as well Fixes #104284 r? rust-lang/risc-v
2023-01-13Improve linker-flavor detectionJonathan Schwender-1/+10
Linker drivers such as gcc, clang or lld often have a version postfix, e.g clang-12. The previous logic would not account for this and would fall back to guessing the linker flavor to be the default linker flavor for the target, which causes linker errors when this is not the case. By accounting for the possible version postfix and also considering g++ and clang++, we considerably reduce the amount of times the fallback guess has to be used. To simplify matching check for a version postfix and match against the linker stem without any version postfix. In contrast to gcc, clang supports all architectures in one binary. This means there are no variants like `aarch64-linux-gnu-clang` and there is no need to check for `-clang` variants.

JhonnyBillM:migrate-codegen-ssa-to-diagnostics-structs-pt3, r=davidtwco Migrate `codegen_ssa` to diagnostics structs - [Part 3] Completes migrating `codegen_ssa` module except 2 outstanding errors that depend on other crates: 1. [`rustc_middle::mir::interpret::InterpError`](https://github.com/rust-lang/rust/blob/b6097f2e1b2ca62e188ba53cf43bd66b06b36915/compiler/rustc_middle/src/mir/interpret/error.rs#L475): I saw `rustc_middle` is unassigned, I am open to take this work. 2. `codegen_llvm`'s use of `fn span_invalid_monomorphization_error`, which I started to replace in the [last commit](https://github.com/rust-lang/rust/commit/9a31b3cdda78a2c0891828254fe9886e0a1cfd16) of this PR, but would like to know the team's preference on how we should keep replacing the other macros: 2.1. Update macros to expect a `Diagnostic` 2.2. Remove macros and expand the code on each use. See [some examples of the different options in this experimental commit](https://github.com/JhonnyBillM/rust/commit/64aee83e80857dcfa450f0c6e31d5f29c6d577e6) _Part 2 - https://github.com/rust-lang/rust/pull/103792_ r? ``@davidtwco`` Cc ``@compiler-errors``

Small fixes for --crate-type staticlib The first commit doesn't have an effect until we start translating error messages. The second commit fixes potential linker errors when combining `--crate-type staticlib` with another crate type and I think `-Cprefer-dynamic`.

2023-01-02only specify --target by default for -Zgcc-ld=lld on wasmRémy Rakic-1/+20
On macOS, it's not yet clear which cases of clang/OS/target/SDK version impact how to find ld/lld/rust-lld. The --target is not needed on our current targets with a vanilla config, but may be in some cases. Specifying it all the time breaks the 10.7+ targets on x64 macOS. We try to only specify it on macOS if the linker flavors are different, for possible cases of cross-compilation with `-Zgcc-ld=lld` but the expectation is that it should be passed manually when needed in these situations.
