🔬 This is a nightly-only experimental API. (rustc_private)

Optional aspects of a target specification.

This has an implementation of Default, see each field for what the default is. In general, these try to take "minimal defaults" that don't assume anything about the runtime they run in.

Fields

🔬 This is a nightly-only experimental API. (rustc_private)
🔬 This is a nightly-only experimental API. (rustc_private)

Linker arguments that are unconditionally passed after any user-defined but before post_link_objects. Standard platform libraries that should be always be linked to, usually go here.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether dynamic linking is available on this target. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Code model to use. Corresponds to llc -code-model=$code_model. Defaults to "default".

🔬 This is a nightly-only experimental API. (rustc_private)

Do not emit code that uses the "red zone", if the ABI has one. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Eliminate frame pointers from stack frames if possible. Defaults to true.

Emit each function in its own section. Defaults to true.

🔬 This is a nightly-only experimental API. (rustc_private)

String to append to the name of every executable.

🔬 This is a nightly-only experimental API. (rustc_private)

String to prepend to the name of every static library. Defaults to "lib".

🔬 This is a nightly-only experimental API. (rustc_private)

String to append to the name of every static library. Defaults to ".a".

🔬 This is a nightly-only experimental API. (rustc_private)

OS family to use for conditional compilation. Valid options: "unix", "windows".

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target toolchain is like OpenBSD's. Only useful for compiling against OpenBSD, for configuring abi when returning a struct.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target toolchain is like OSX's. Only useful for compiling against iOS/OS X, in particular running dsymutil and some other stuff like -dead_strip. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target toolchain is like Solaris's. Only useful for compiling against Illumos/Solaris, as they have a different set of linker flags. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target toolchain is like Windows'. Only useful for compiling against Windows, only really used for figuring out how to find libraries, since Windows uses its own library naming convention. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)
🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target toolchain is like Android's. Only useful for compiling against Android. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target toolchain is like Emscripten's. Only useful for compiling with Emscripten toolchain. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the linker support GNU-like arguments such as -O. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

The MinGW toolchain has a known issue that prevents it from correctly handling COFF object files with more than 215 sections. Since each weak symbol needs its own COMDAT section, weak linkage implies a large number sections that easily exceeds the given limit for larger codebases. Consequently we want a way to disallow weak linkage on some platforms.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the linker support rpaths or not. Defaults to false.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether to disable linking to the default libraries, typically corresponds to -nodefaultlibs. Defaults to true.

🔬 This is a nightly-only experimental API. (rustc_private)

Dynamically linked executables can be compiled as position independent if the default relocation model of position independent code is not changed. This is a requirement to take advantage of ASLR, as otherwise the functions in the executable are not randomized and can be used during an exploit of a vulnerability in any code.

🔬 This is a nightly-only experimental API. (rustc_private)

Format that archives should be emitted in. This affects whether we use LLVM to assemble an archive or fall back to the system linker, and currently only "gnu" is used to fall into LLVM. Unknown strings cause the system linker to be used.

🔬 This is a nightly-only experimental API. (rustc_private)

Is asm!() allowed? Defaults to true.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether the target uses a custom unwind resumption routine. By default LLVM lowers resume instructions into calls to _Unwind_Resume defined in libgcc. If this option is enabled, the target must provide eh_unwind_resume lang item.

🔬 This is a nightly-only experimental API. (rustc_private)

Default crate for allocation symbols to link against

🔬 This is a nightly-only experimental API. (rustc_private)
🔬 This is a nightly-only experimental API. (rustc_private)

Flag indicating whether ELF TLS (e.g. #[thread_local]) is available for this target.

🔬 This is a nightly-only experimental API. (rustc_private)

Don't use this field; instead use the .min_atomic_width() method.

🔬 This is a nightly-only experimental API. (rustc_private)

Don't use this field; instead use the .max_atomic_width() method.

🔬 This is a nightly-only experimental API. (rustc_private)

Panic strategy: "unwind" or "abort"

🔬 This is a nightly-only experimental API. (rustc_private)

A blacklist of ABIs unsupported by the current target. Note that generic ABIs are considered to be supported on all platforms and cannot be blacklisted.

🔬 This is a nightly-only experimental API. (rustc_private)

Whether or not the CRT is statically linked by default.

Trait Implementations
