This was necessary before, because `declare_raw_fn` would always apply the default optimization attributes to every declared function, and then `attributes::from_fn_attrs` would have to remove the default attributes in the case of, e.g. `#[optimize(speed)]` in a `-Os` build. However, every relevant callsite of `declare_raw_fn` (i.e. where we actually generate code for the function, and not e.g. a call to an intrinsic, where optimization attributes don't [?] matter) calls `from_fn_attrs`, so we can simply remove the attribute setting from `declare_raw_fn`, and rely on `from_fn_attrs` to apply the correct attributes all at once. |

This directory currently contains some LLVM support code. This will generally be sent upstream to LLVM in time; for now it lives here. NOTE: the LLVM C++ ABI is subject to between-version breakage and must *never* be exposed to Rust. To allow for easy auditing of that, all Rust-exposed types must be typedef-ed as "LLVMXyz", or "LLVMRustXyz" if they were defined here. Functions that return a failure status and leave the error in the LLVM last error should return an LLVMRustResult rather than an int or anything to avoid confusion. When translating enums, add a single `Other` variant as the first one to allow for new variants to be added. It should abort when used as an input. All other types must not be typedef-ed as such.
