rustc, rustc_passes: reduce deps on rustc_expand Part of #65324. r? @petrochenkov
2019-10-27Always use consteval to codegen caller_location.Adam Perry-2/+0
2019-10-27Panicking infra uses &core::panic::Location.Adam Perry-9/+0
This allows us to remove `static_panic_msg` from the SSA<->LLVM boundary, along with its fat pointer representation for &str. Also changes the signature of PanicInfo::internal_contructor to avoid copying. Closes #65856.
2019-10-27Implement core::intrinsics::caller_location.Adam Perry-0/+4
Returns a `&core::panic::Location` corresponding to where it was called, also making `Location` a lang item.
2019-10-27rustc, rustc_passes: don't depend on syntax_expand.Mazdak Farrokhzad-1/+1
This is done by moving some data definitions to syntax::expand.
2019-10-21Use `Symbol` for codegen unit names.Nicholas Nethercote-2/+2
This is a straightforward replacement except for two places where we have to convert to `LocalInternedString` to get a stable sort.

2019-10-10Auto merge of #59546 - sfanxiang:interminable-ub, r=nagisabors-0/+1
Add llvm.sideeffect to potential infinite loops and recursions LLVM assumes that a thread will eventually cause side effect. This is not true in Rust if a loop or recursion does nothing in its body, causing undefined behavior even in common cases like `loop {}`. Inserting llvm.sideeffect fixes the undefined behavior. As a micro-optimization, only insert llvm.sideeffect when jumping back in blocks or calling a function. A patch for LLVM is expected to allow empty non-terminate code by default and fix this issue from LLVM side. https://github.com/rust-lang/rust/issues/28728 **UPDATE:** [Mentoring instructions here](https://github.com/rust-lang/rust/pull/59546#issuecomment-515072429) to unstall this PR

2019-09-26Rollup merge of #64772 - Mark-Simulacrum:no-tyctxt-tx, r=eddybMazdak Farrokhzad-1/+7
Remove tx_to_llvm_workers from TyCtxt This can be kept within the codegen backend crates entirely -- there's no reason for us to create it outside and attempt to hold it in the (global) context. Changes here aren't really too easily reviewable I suspect -- not sure if they can be cleaned up by splitting into more commits though, it's just hard to reason about `Box<Any>` in general. If there are thoughts though I'd be happy to hear them. The primary goal of this PR is to get rid of the field on `rustc_interface::Queries`.

2019-07-12Replace `struct_tail` and `struct_lockstep_tails` with variants handling ↵Felix S. Klock II-2/+3
normalization. The old struct tail functions did not deal with `<T as Trait>::A` and `impl Trait`, at least not explicitly. (We didn't notice this bug before because it is only exposed when the tail (post deep normalization) is not `Sized`, so it was a rare case to deal with.) For post type-checking (i.e. during codegen), there is now `struct_tail_erasing_lifetimes` and `struct_lockstep_tails_erasing_lifetimes`, which each take an additional `ParamEnv` argument to drive normalization. For pre type-checking cases where normalization is not needed, there is `struct_tail_without_normalization`. (Currently, the only instance of this is `Expectation::rvalue_hint`.) All of these new entrypoints work by calling out to common helper routines. The helpers are parameterized over a closure that handles the normalization.

2019-06-18Auto merge of #59625 - immunant:copy_variadics_typealias, r=eddybbors-2/+2
Refactor C FFI variadics to more closely match their C counterparts, and add Clone implementation We had to make some changes to expose `va_copy` and `va_end` directly to users (mainly for C2Rust, but not exclusively): - redefine the Rust variadic structures to more closely correspond to C: `VaList` now matches `va_list`, and `VaListImpl` matches `__va_list_tag` - add `Clone` for `VaListImpl` - add explicit `as_va_list()` conversion function from `VaListImpl` to `VaList` - add deref coercion from `VaList` to `VaListImpl` - add support for the `asmjs` target All these changes were needed for use cases like: ```Rust let mut ap2 = va_copy(ap); vprintf(fmt, ap2); va_end(&mut ap2); ```
