Mazdak Farrokhzad 37333b5131 Rollup merge of #63492 - eddyb:cvarargs, r=nagisa,matthewjasper ... Remove redundancy from the implementation of C variadics. This cleanup was first described in https://github.com/rust-lang/rust/issues/44930#issuecomment-497163539: * AST doesn't track `c_variadic: bool` anymore, relying solely on a trailing `CVarArgs` type in fn signatures * HIR doesn't have a `CVarArgs` anymore, relying solely on `c_variadic: bool` * same for `ty::FnSig` (see tests for diagnostics improvements from that) * `{hir,mir}::Body` have one extra argument than the signature when `c_variadic == true` * `rustc_typeck` and `rustc_mir::{build,borrowck}` need to give that argument the right type (which no longer uses a lifetime parameter, but a function-internal scope) * `rustc_target::abi::call` doesn't need special hacks anymore (since it never sees the `VaListImpl` now, it's all inside the body) r? @nagisa / @rkruppe cc @dlrobertson @oli-obk		2019-09-29 04:35:58 +02:00
