History

bors c42d846add Auto merge of #94229 - erikdesjardins:rem2, r=nikic Remove LLVM attribute removal This was necessary before, because `declare_raw_fn` would always apply the default optimization attributes to every declared function. Then `attributes::from_fn_attrs` would have to remove the default attributes in the case of, e.g. `#[optimize(speed)]` in a `-Os` build. (see [`src/test/codegen/optimize-attr-1.rs`](`03a8cc7df1/src/test/codegen/optimize-attr-1.rs (L33)`)) 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 remove the attribute setting from `declare_raw_fn`, and rely on `from_fn_attrs` to apply the correct attributes all at once. r? `@ghost` (blocked on #94221) `@rustbot` label S-blocked		2022-03-02 08:48:33 +00:00

README

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.
