History

Josh Stone 35adb36779 Avoid LLVM-deprecated `Optional::hasValue` LLVM 15 added `Optional::has_value`, and LLVM `main` (16) has deprecated `hasValue`. However, its `explicit operator bool` does the same thing, and was added long ago, so we can use that across our full LLVM range of compatibility.		2022-09-26 16:51:18 -07:00

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.
