rustc: Implement stack probes for x86

2017-07-06T15:58:19+00:00

This commit implements stack probes on x86/x86_64 using the freshly landed support upstream in LLVM. The purpose of stack probes here are to guarantee a segfault on stack overflow rather than having a chance of running over the guard page already present on all threads by accident. At this time there's no support for any other architecture because LLVM itself does not have support for other architectures.

-Z linker-flavor

2017-04-07T15:52:42+00:00

This patch adds a `-Z linker-flavor` flag to rustc which can be used to invoke the linker using a different interface. For example, by default rustc assumes that all the Linux targets will be linked using GCC. This makes it impossible to use LLD as a linker using just `-C linker=ld.lld` because that will invoke LLD with invalid command line arguments. (e.g. rustc will pass -Wl,--gc-sections to LLD but LLD doesn't understand that; --gc-sections would be the right argument) With this patch one can pass `-Z linker-flavor=ld` to rustc to invoke the linker using a LD-like interface. This way, `rustc -C linker=ld.lld -Z linker-flavor=ld` will invoke LLD with the right arguments. `-Z linker-flavor` accepts 4 different arguments: `em` (emcc), `ld`, `gcc`, `msvc` (link.exe). `em`, `gnu` and `msvc` cover all the existing linker interfaces. `ld` is a new flavor for interfacing GNU's ld and LLD. This patch also changes target specifications. `linker-flavor` is now a mandatory field that specifies the *default* linker flavor that the target will use. This change also makes the linker interface *explicit*; before, it used to be derived from other fields like linker-is-gnu, is-like-msvc, is-like-emscripten, etc. Another change to target specifications is that the fields `pre-link-args`, `post-link-args` and `late-link-args` now expect a map from flavor to linker arguments. ``` diff - "pre-link-args": ["-Wl,--as-needed", "-Wl,-z,-noexecstack"], + "pre-link-args": { + "gcc": ["-Wl,--as-needed", "-Wl,-z,-noexecstack"], + "ld": ["--as-needed", "-z,-noexecstack"], + }, ``` [breaking-change] for users of custom targets specifications

change max_atomic_width type from u64 to Option

to better express the idea that omitting this field defaults this value to target_pointer_width

librustc_back: convert fn target() to return Result

2016-07-27T17:28:40+00:00

Change all the target generation functions to return a Result so that targets that are unable to be instantiated can be expressed as an Err instead of a panic!(). This should improve #33497 as well.

Add #[cfg(target_has_atomic)] to get atomic support for the current target

2016-05-09T12:31:47+00:00

Make data-layout mandatory in target specs.
