Rémy Rakic 77d01103a3 filter LLVM diagnostics before crossing the rust bridge this will eliminate many short-lived allocations (e.g. 20% of the memory used building cargo) when unpacking the diagnostic and converting its various C++ strings into rust strings, just to be filtered out most of the time.		2023-08-01 21:01:20 +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.
