Split inline const to two feature gates and mark expression position inline const complete This PR splits inline const in pattern position into its own `#![feature(inline_const_pat)]` feature gate, and make the usage in expression position complete. I think I have resolved most outstanding issues related to `inline_const` with #89561 and other PRs. The only thing left that I am aware of is #90150 and the lack of lifetime checks when inline const is used in pattern position (FIXME in #89561). Implementation-wise when used in pattern position it has to be lowered during MIR building while in expression position it's evaluated only when monomorphizing (just like normal consts), so it makes some sense to separate it into two feature gates so one can progress without being blocked by another. ``@rustbot`` label: T-compiler F-inline_const

std: Get the standard library compiling for wasm64 This commit goes through and updates various `#[cfg]` as appropriate to get the wasm64-unknown-unknown target behaving similarly to the wasm32-unknown-unknown target. Most of this is just updating various conditions for `target_arch = "wasm32"` to also account for `target_arch = "wasm64"` where appropriate. This commit also lists `wasm64` as an allow-listed architecture to not have the `restricted_std` feature enabled, enabling experimentation with `-Z build-std` externally. The main goal of this commit is to enable playing around with `wasm64-unknown-unknown` externally via `-Z build-std` in a way that's similar to the `wasm32-unknown-unknown` target. These targets are effectively the same and only differ in their pointer size, but wasm64 is much newer and has much less ecosystem/library support so it'll still take time to get wasm64 fully-fledged.

2021-11-11Auto merge of #83846 - torhovland:issue-10971, r=davidtwcobors-0/+10
Added the --temps-dir option Fixes #10971. The new `--temps-dir` option puts intermediate files in a user-specified directory. This provides a fix for the issue where parallel invocations of rustc would overwrite each other's intermediate files. No files are kept in the intermediate directory unless `-C save-temps=yes`. If additional files are specifically requested using `--emit asm,llvm-bc,llvm-ir,obj,metadata,link,dep-info,mir`, these will be put in the output directory rather than the intermediate directory. This is a backward-compatible change, i.e. if `--temps-dir` is not specified, the behavior is the same as before.
2021-11-10Rollup merge of #90736 - Lokathor:inline-asm-docs-updates, r=AmanieuMatthias Krüger-2/+5
adjust documented inline-asm register constraints This change more clearly specifies how `reg` and `reg_thumb` work with ARM, Thumb2, and Thumb1 code. Based upon the [llvm documentation](https://llvm.org/docs/LangRef.html#supported-constraint-code-list) for register constraint codes. To be clear, this just updates the docs to match what already happens with rustc/llvm. No change in the compiler is required to make it match this new documentation.

2021-11-09Rollup merge of #90035 - SparrowLii:rfc2528, r=jackh726Matthias Krüger-0/+33
implement rfc-2528 type_changing-struct-update This PR implement rfc2528-type_changing-struct-update. The main change process is as follows: 1. Move the processing part of `base_expr` into `check_expr_struct_fields` to avoid returning `remaining_fields` (a relatively complex hash table) 2. Before performing the type consistency check(`check_expr_has_type_or_error`), if the `type_changing_struct_update` feature is set, enter a different processing flow, otherwise keep the original flow 3. In the case of the same structure definition, check each field in `remaining_fields`. If the field in `base_expr` is not the suptype of the field in `adt_ty`, an error(`FeildMisMatch`) will be reported. The MIR part does not need to be changed, because only the items contained in `remaining_fields` will be extracted from `base_expr` when MIR is generated. This means that fields with different types in `base_expr` will not be used Updates #86618 cc `@nikomatsakis`

2021-11-03Add note about x86 instruction prefixes in asm!Smittyvb-0/+2
Since rustc doesn't do the assembly parsing itself, it is unable to detect when inline assembly ends with an instruction prefix, which doesn't make sense since it would apply to instructions from the compiler. This fixes #82314 by mentioning that x86 instruction prefixes must not be used in inline assembly.
