History

Augie Fackler 1c26dd0db4 RustWrapper: adapt to APInt API changes in LLVM 15 In https://reviews.llvm.org/D125556 upstream changed sext() and zext() to allow some no-op cases, which previously required use of the OrSelf() methods, which I assume is what was going on here. The OrSelf() methods got removed in https://reviews.llvm.org/D125559 after two weeks of deprecation because they came with some bonus (probably-undesired) behavior. Since the behavior of sext() and zext() changed slightly, I kept the old *OrSelf() calls in LLVM 14 and earlier, and only use the new version in LLVM 15. r? @nikic		2022-06-07 14:47:57 -04:00

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.
