2022-03-04Auto merge of #94159 - erikdesjardins:align-load, r=nikicbors-8/+30
Add !align metadata on loads of &/&mut/Box Note that this refers to the alignment of what the loaded value points to, _not_ the alignment of the loaded value itself. r? `@ghost` (blocked on #94158)
2022-03-01Auto merge of #94402 - erikdesjardins:revert-coldland, r=nagisabors-14/+3
Revert "Auto merge of #92419 - erikdesjardins:coldland, r=nagisa" Should fix (untested) #94390 Reopens #46515, #87055 r? `@ehuss`

2022-02-27Revert "Auto merge of #92419 - erikdesjardins:coldland, r=nagisa"Erik Desjardins-14/+3
This reverts commit 4f49627c6fe2a32d1fed6310466bb0e1c535c0c0, reversing changes made to 028c6f1454787c068ff5117e9000a1de4fd98374.
2022-02-27Apply noundef metadata to loads of types that do not permit raw initErik Desjardins-0/+14
This matches the noundef attributes we apply on arguments/return types.
2022-02-26Add LLVM attributes in batches instead of individuallyErik Desjardins-2/+8
This should improve performance.
2022-02-24Introduce Bx::switch_to_blockbjorn3-0/+4
2022-02-20Remove build_sibling_blockbjorn3-13/+11
2022-01-24Merge landing_pad and set_cleanup into cleanup_landing_padbjorn3-16/+18
2022-01-24Merge add_handler into catch_switchbjorn3-8/+8
Some codegen backends may require all handlers to be immediately known
2022-01-24Remove unused return values from resume and cleanup_retbjorn3-10/+9
Given that these instructions are diverging, not every codegen backend may be able to produce a return value for them.

2021-12-30keep noinline for system llvm < 14Erik Desjardins-1/+8
2021-12-29Mark drop calls in landing pads cold instead of noinlineErik Desjardins-2/+2
Now that deferred inlining has been disabled in LLVM, this shouldn't cause catastrophic size blowup.
2021-12-16Remove `in_band_lifetimes` from `rustc_codegen_llvm`LegionMammal978-12/+12
See #91867 for more information.
2021-11-10Use more robust checks in rustc for wasmAlex Crichton-2/+2
2021-11-10Update more rustc/libtest things for wasm64Alex Crichton-2/+2
* Add wasm64 variants for inline assembly along the same lines as wasm32 * Update a few directives in libtest to check for `target_family` instead of `target_arch` * Update some rustc codegen and typechecks specialized for wasm32 to also work for wasm64.

2021-10-27Auto merge of #89652 - rcvalle:rust-cfi, r=nagisabors-0/+26
Add LLVM CFI support to the Rust compiler This PR adds LLVM Control Flow Integrity (CFI) support to the Rust compiler. It initially provides forward-edge control flow protection for Rust-compiled code only by aggregating function pointers in groups identified by their number of arguments. Forward-edge control flow protection for C or C++ and Rust -compiled code "mixed binaries" (i.e., for when C or C++ and Rust -compiled code share the same virtual address space) will be provided in later work as part of this project by defining and using compatible type identifiers (see Type metadata in the design document in the tracking issue #89653). LLVM CFI can be enabled with -Zsanitizer=cfi and requires LTO (i.e., -Clto). Thank you, `@eddyb` and `@pcc,` for all the help!

2021-08-25Auto merge of #88242 - bonega:allocation_range, r=oli-obkbors-2/+1
Use custom wrap-around type instead of RangeInclusive Two reasons: 1. More memory is allocated than necessary for `valid_range` in `Scalar`. The range is not used as an iterator and `exhausted` is never used. 2. `contains`, `count` etc. methods in `RangeInclusive` are doing very unhelpful(and dangerous!) things when used as a wrap-around range. - In general this PR wants to limit potentially confusing methods, that have a low probability of working. Doing a local perf run, every metric shows improvement except for instructions. Max-rss seem to have a very consistent improvement. Sorry - newbie here, probably doing something wrong.

2021-08-05Prepare call/invoke for opaque pointersJosh Stone-22/+24
Rather than relying on `getPointerElementType()` from LLVM function pointers, we now pass the function type explicitly when building `call` or `invoke` instructions.
2021-08-04Prepare inbounds_gep for opaque pointersTomasz Miąsko-3/+13
Implement inbounds_gep using LLVMBuildInBoundsGEP2 which takes an explicit type argument instead of deriving it from a pointer type.

2021-07-18Auto merge of #86950 - tmiasko:personality, r=nagisabors-1/+5
Use existing declaration of rust_eh_personality If crate declares `rust_eh_personality`, re-use existing declaration as otherwise attempts to set function attributes that follow the declaration will fail (unless it happens to have exactly the same type signature as the one predefined in the compiler). Fixes #70117. Fixes https://github.com/rust-lang/rust/pull/81469#issuecomment-809428126; probably.

2021-07-09Pass type when creating loadNikita Popov-20/+9
This makes load generation compatible with opaque pointers. The generation of nontemporal copies still accesses the pointer element type, as fixing this requires more movement.
2021-07-09Pass type when creating atomic loadNikita Popov-0/+2
Instead of determining it from the pointer type, explicitly pass the type to load.
