2019-02-27Rename variadic to c_variadicDan Robertson-5/+5
Function signatures with the `variadic` member set are actually C-variadic functions. Make this a little more explicit by renaming the `variadic` boolean value, `c_variadic`.
2019-02-27Support defining C compatible variadic functionsDan Robertson-6/+39
Add support for defining C compatible variadic functions in unsafe rust with extern "C".

librustc_codegen_llvm: Don't eliminate empty structs in C ABI on linux-sparc64 This is in accordance with the SPARC Compliance Definition 2.4.1, Page 3P-12. It says that structs of up to 8 bytes (which applies to empty structs as well) are to be passed in one register.

2018-12-21Enable emission of alignment attrs for pointer paramsNikita Popov-6/+0
Instead disable creation of assumptions during inlining using an LLVM opt flag. The -Z arg-align-attributes option which previously controlled this behavior is removed.

2018-11-11Auto merge of #54993 - TimNN:pda-tdl, r=eddybbors-1/+9
Support for the program data address space option of LLVM's Target Datalayout This was introduced recently (specifically, for AVR, cc @dylanmckay). (I came up with this when attempting to run [avr-rust](https://github.com/avr-rust/rust) rebased on the latest [rust-lang](https://github.com/rust-lang/rust) commits. If this requires a different design, some additional discussions, or is not something to pursue right now, I'd be happy to close this PR). Note that this somewhat overlaps with @DiamondLovesYou's #51576, I think, although the implementation here is significantly simpler: Since the address space applies to _all_ program data, we can just check the pointee's type whenever we create an LLVM pointer type. If it is a function we use the program data address space; if not we use the default address space. cc @eddyb, who has been reviewing #51576 Ref: https://llvm.org/docs/LangRef.html#data-layout

2018-11-04Support memcpy/memmove with differing src/dst alignmentNikita Popov-1/+2
If LLVM 7 is used, generate memcpy/memmove with differing src/dst alignment. I've added new FFI functions to construct these through the builder API, which is more convenient than dealing with differing intrinsic signatures depending on the LLVM version.

2018-11-01Implement object-safety for arbitrary_self_types: part 2Michael Hewson-13/+36
For now, all of the receivers that we care about are just a newtyped pointer — i.e. `Box<Self>`, `Rc<Self>`, `Pin<Box<Self>>`, `Pin<&mut Self>`. This is much simpler to implement in codeine than the more general case, because the ABI is the same as a pointer. So we add some checks in typeck/coherence/builtin.rs to make sure that implementors of CoerceSized are just newtyped pointers. In this commit, we also implement the codegen bits.

2018-10-12rustc: Allow targets to specify SIMD args are by-valAlex Crichton-1/+4
The upcoming SIMD support in the wasm target is unique from the other platforms where it's either unconditionally available or not available, there's no halfway where a subsection of the program can use it but no other parts of the program can use it. In this world it's valid for wasm SIMD args to always be passed by value and there's no need to pass them by reference. This commit adds a new custom target specification option `simd_types_indirect` which defaults to `true`, but the wasm backend disables this and sets it to `false`.

2018-07-13Add the `amdgpu-kernel` ABI.Richard Diamond-0/+2
Technically, there are requirements imposed by the LLVM `AMDGPUTargetMachine` on functions with this ABI (eg, the return type must be void), but I'm unsure exactly where this should be enforced.
