The entire code is available here, Dockerfile included. |

I managed to minimize the code: #![feature(rustc_private)]
extern crate rustc_codegen_llvm;
extern crate rustc_driver;
fn main() {
unsafe {
rustc_codegen_llvm::llvm::LLVMRustContextCreate(true);
}
} |

…imulacrum Add a few known-bug tests The labels of these tests should be changed from `S-bug-has-mcve` to `S-bug-has-test` once this is merged. cc: rust-lang#101518 rust-lang#99492 rust-lang#90950 rust-lang#89196 rust-lang#104034 rust-lang#101350 rust-lang#103705 rust-lang#103899 I couldn't reproduce the failures in rust-lang#101962 and rust-lang#100772 (so either these have started passing, or I didn't repro properly), so leaving those out for now. rust-lang#102065 was a bit more complicated, since it uses `rustc_private` and I didn't want to mess with that.

If `interactive` is set to true, codegen will special case that to get faster and for the resulting LLVM IR to be executable from external programs such as REPL. This commit also has the following changes: - Added LLVM JIT-related API. - Stopped distributing rustc crates as rmeta files. See added code comment and rust-lang#102065 for detailed info. - Some visibility changes on existing APIs so they could be used by external programs.

I tried this code, which builds and runs without problem:
However, after I make this change:
I expected to see this happen: The compiler builds without errors.
Instead, this happened:
cargo buildfails with the message shown in "Output" section below.Meta
rustc --version --verbose:Output
The text was updated successfully, but these errors were encountered:
