bingen

将编译时编译的汇编代码作为二进制切片的进程宏。

[dependencies]
bingen = "0.3"

let bin = bingen!("aarch64-linux-eabi", "mrs x0, DBGDTR_EL0");
assert_eq!(bin, [0, 4, 51, 213]);

默认情况下，此crate会自动检测最新的llvm工具链安装。

如果您想使用其他llvm安装，请手动指定路径，如下所示

BINGEN_CLANG_PATH=/path/to/clang \
  BINGEN_OBJCOPY_PATH=/path/to/llvm-objcopy \
  cargo test

要了解默认使用的工具链，请运行以下命令

$ cargo test --lib tests::print_llvm_path -- --nocapture --ignored
    Finished test [unoptimized + debuginfo] target(s) in 0.02s
     Running unittests (target/debug/deps/bingen-4b08a2f2272400c9)

test tests::print_llvm_path ... ok

test result: ok. 1 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 0.00s
