2020-12-03Combination of commitsRich Kadel-3/+0
Fixes multiple issue with counters, with simplification Includes a change to the implicit else span in ast_lowering, so coverage of the implicit else no longer spans the `then` block. Adds coverage for unused closures and async function bodies. Fixes: #78542 Adding unreachable regions for known MIR missing from coverage map Cleaned up PR commits, and removed link-dead-code requirement and tests Coverage no longer depends on Issue #76038 (`-C link-dead-code` is no longer needed or enforced, so MSVC can use the same tests as Linux and MacOS now) Restrict adding unreachable regions to covered files Improved the code that adds coverage for uncalled functions (with MIR but not-codegenned) to avoid generating coverage in files not already included in the files with covered functions. Resolved last known issue requiring --emit llvm-ir workaround Fixed bugs in how unreachable code spans were added.
2020-11-20Never inline naked functionsTomasz Miąsko-3/+9
The `#[naked]` attribute disabled prologue / epilogue emission for the function and it is responsibility of a developer to provide them. The compiler is no position to inline such functions correctly. Disable inlining of naked functions at LLVM and MIR level.
2020-11-17Fix setting inline hint based on `InstanceDef::requires_inline`Tomasz Miąsko-12/+4
For instances where `InstanceDef::requires_inline` is true, an attempt is made to set an inline hint though a call to the `inline` function. The attempt is ineffective, since all attributes will be usually removed by the second call. Fix the issue by applying the attributes only once, with user provided attributes having a priority when provided.

2020-11-12Dropped Support for Bidirectional Custom Target Definition EmulationDevJPM-12/+0
as requested in the review and argued that this is only consistent with later LLVM upgrades
2020-11-12fully exploited the dropped support of LLVM 8DevJPM-11/+3
This commit grepped for LLVM_VERSION_GE, LLVM_VERSION_LT, get_major_version and min-llvm-version and statically evaluated every expression possible (and sensible) assuming that the LLVM version is >=9 now
2020-11-08rustc_target: Rename some target options to avoid tautologyVadim Petrochenkov-1/+1
`target.target_endian` -> `target.endian` `target.target_c_int_width` -> `target.c_int_width` `target.target_os` -> `target.os` `target.target_env` -> `target.env` `target.target_vendor` -> `target.vendor` `target.target_family` -> `target.os_family` `target.target_mcount` -> `target.mcount`
2020-11-08Collapse all uses of `target.options.foo` into `target.foo`Vadim Petrochenkov-4/+2
with an eye on merging `TargetOptions` into `Target`. `TargetOptions` as a separate structure is mostly an implementation detail of `Target` construction, all its fields logically belong to `Target` and available from `Target` through `Deref` impls.

2020-10-15Remove rustc_session::config::Configest31-1/+0
The wrapper type led to tons of target.target across the compiler. Its ptr_width field isn't required any more, as target_pointer_width is already present in parsed form.
2020-10-15Replace target.target with target and target.ptr_width with target.pointer_widthest31-5/+4
Preparation for a subsequent change that replaces rustc_target::config::Config with its wrapped Target. On its own, this commit breaks the build. I don't like making build-breaking commits, but in this instance I believe that it makes review easier, as the "real" changes of this PR can be seen much more easily.

2020-10-14Rollup merge of #77795 - bjorn3:codegen_backend_interface_refactor, r=oli-obkDylan DPC-18/+2
Codegen backend interface refactor This moves several things away from the codegen backend to rustc_interface. There are a few behavioral changes where previously the incremental cache (incorrectly) wouldn't get finalized, but now it does. See the individual commit messages.
2020-10-13Auto merge of #76830 - Artoria2e5:tune, r=nagisabors-0/+15
Pass tune-cpu to LLVM I think this is how it should work... See https://internals.rust-lang.org/t/expose-tune-cpu-from-llvm/13088 for the background. Or the documentation diff.

2020-10-04Move target feature whitelist from cg_llvm to cg_ssabjorn3-5/+3
These target features have to be supported or at least emulated by alternative codegen backends anyway as they are used by common crates. By moving this list to cg_ssa, other codegen backends don't have to copy this code.
2020-09-30Add support for cmse_nonsecure_entry attributeHugues de Valon-0/+3
This patch adds support for the LLVM cmse_nonsecure_entry attribute. This is a target-dependent attribute that only has sense for the thumbv8m Rust targets. You can find more information about this attribute here: https://developer.arm.com/documentation/ecm0359818/latest/ Signed-off-by: Hugues de Valon <hugues.devalon@arm.com>
