2019-08-29Rollup merge of #63979 - alexcrichton:remove-wasm-syscall, r=dtolnayMazdak Farrokhzad-374/+19
std: Remove the `wasm_syscall` feature This commit removes the `wasm_syscall` feature from the wasm32-unknown-unknown build of the standard library. This feature was originally intended to allow an opt-in way to interact with the operating system in a posix-like way but it was never stabilized. Nowadays with the advent of the `wasm32-wasi` target that should entirely replace the intentions of the `wasm_syscall` feature.
2019-08-29Rollup merge of #63956 - alexcrichton:fix-lto-all-cached, r=michaelwoeristerMazdak Farrokhzad-49/+59
rustc: Handle modules in "fat" LTO more robustly When performing a "fat" LTO the compiler has a whole mess of codegen units that it links together. To do this it needs to select one module as a "base" module and then link everything else into this module. Previously LTO passes assume that there's at least one module in-memory to link into, but nowadays that's not always true! With incremental compilation modules may actually largely be cached and it may be possible that there's no in-memory modules to work with. This commit updates the logic of the LTO backend to handle modules a bit more uniformly during a fat LTO. This commit immediately splits them into two lists, one serialized and one in-memory. The in-memory list is then searched for the largest module and failing that we simply deserialize the first serialized module and link into that. This refactoring avoids juggling three lists, two of which are serialized modules and one of which is half serialized and half in-memory. Closes #63349

resolve: Block expansion of a derive container until all its derives are resolved So, it turns out there's one more reason to block expansion of a `#[derive]` container until all the derives inside it are resolved, beside `Copy` (https://github.com/rust-lang/rust/pull/63248). The set of derive helper attributes registered by derives in the container also has to be known before the derives themselves are expanded, otherwise it may be too late (see https://github.com/rust-lang/rust/pull/63468#issuecomment-524550872 and the `#[stable_hasher]`-related test failures in https://github.com/rust-lang/rust/pull/63468). So, we stop our attempts to unblock the container earlier, as soon as the `Copy` status is known, and just block until all its derives are resolved. After all the derives are resolved we immediately go and process their helper attributes in the item, without delaying it until expansion of the individual derives.

2019-08-29Rollup merge of #63980 - DutchGhost:master, r=cramertjMazdak Farrokhzad-0/+1
add missing `#[repr(C)]` on the Slices union Adds the `#[repr(C)]` attribute to the `Slices` union used to convert an `&str` into a `&[u8]`. Without the attribute, the union has an unspecified layout: https://doc.rust-lang.org/reference/types/union.html, so performing the 'transmute' is unsound without the attribute (as far as I understand). The `Repr` union, used for converting a raw ptr + len to a slice has this attribute as well: https://github.com/rust-lang/rust/blob/master/src/libcore/ptr/mod.rs#L211-#L216
