The default diagnostic handler considers all remarks to be disabled by default unless configured otherwise through LLVM internal flags: `-pass-remarks`, `-pass-remarks-missed`, and `-pass-remarks-analysis`. This behaviour makes `-Cremark` ineffective on its own. Fix this by configuring a custom diagnostic handler that enables optimization remarks based on the value of `-Cremark` option. With `-Cremark=all` enabling all remarks.
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.
