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.
