2020-07-22Improve codegen for unchecked float casts on wasmAlex Crichton-38/+74
This commit improves codegen for unchecked casts on WebAssembly targets to use the singluar `iNN.trunc_fMM_{u,s}` instructions. Previously rustc would codegen a bare `fptosi` and `fptoui` for float casts but for WebAssembly targets the codegen for these instructions is quite large. This large codegen is due to the fact that LLVM can speculate these instructions so the trapping behavior of WebAssembly needs to be protected against in case they're speculated. The change here is to update the codegen for the unchecked cast intrinsics to have a wasm-specific case where they call the appropriate LLVM intrinsic to generate the right wasm instruction. The intrinsic is explicitly opting-in to undefined behavior so a trap here for out-of-bounds inputs on wasm should be acceptable. cc #73591

2020-07-22rustdoc: Always warn when linking from public to private itemsDennis Hamester-10/+36
Change the logic such that linking from a public to a private item always triggers intra_doc_link_resolution_failure. Previously, the warning was not emitted when --document-private-items is passed. Also don't rely anymore on the item's visibility, which would falsely trigger the lint now that the check for --document-private-items is gone.

2020-07-22Rollup merge of #74528 - euclio:intra-link-errors, r=jyn514Manish Goregaokar-298/+290
refactor and reword intra-doc link errors This commit refactors intra-doc link error reporting to deduplicate code and decouple error construction from the type of error. This greatly improves flexibility at each error construction site, while reducing the complexity of the diagnostic creation. This commit also rewords the diagnostics for clarity and style: - Diagnostics should not end in periods. - It's unnecessary to say "ignoring it". Since this is a warning by default, it's already clear that the link is ignored.

2020-07-22Auto merge of #73270 - dylanmckay:avr-use-correct-addrspace, r=nagisabors-36/+188
[AVR] Correctly set the pointer address space when constructing pointers to functions NOTE: Pull request iterations: * https://github.com/dylanmckay/rust/releases/tag/avr-use-correct-addrspace.0 * https://github.com/dylanmckay/rust/releases/tag/avr-use-correct-addrspace.1 * https://github.com/dylanmckay/rust/releases/tag/avr-use-correct-addrspace.2 This patch extends the existing `type_i8p` method so that it requires an explicit address space to be specified. Before this patch, the `type_i8p` method implcitily assumed the default address space, which is not a safe transformation on all targets, namely AVR. The Rust compiler already has support for tracking the "instruction address space" on a per-target basis. This patch extends the code generation routines so that an address space must always be specified. In my estimation, around 15% of the callers of `type_i8p` produced invalid code on AVR due to the loss of address space prior to LLVM final code generation. This would lead to unavoidable assertion errors relating to invalid bitcasts. With this patch, the address space is always either 1) explicitly preserved from the input type, or 2) explicitly set to the instruction address space because the logic is dealing with functions which must be placed there, or 3) explicitly set to the default address space 0 because the logic can only operate on data space pointers and thus we keep the existing semantics of assuming the default, "data" address space.
