From 20c301330cf17dd98c58aaff602586b99f7676fc Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Mon, 31 Oct 2016 09:36:30 -0700 Subject: rustc: Add knowledge of Windows subsystems. This commit is an implementation of [RFC 1665] which adds support for the `#![windows_subsystem]` attribute. This attribute allows specifying either the "windows" or "console" subsystems on Windows to the linker. [RFC 1665]: https://github.com/rust-lang/rfcs/blob/master/text/1665-windows-subsystem.md Previously all Rust executables were compiled as the "console" subsystem which meant that if you wanted a graphical application it would erroneously pop up a console whenever opened. When compiling an application, however, this is undesired behavior and the "windows" subsystem is used instead to have control over user interactions. This attribute is validated, but ignored on all non-Windows platforms. cc #37499 --- src/libsyntax/feature_gate.rs | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'src/libsyntax') diff --git a/src/libsyntax/feature_gate.rs b/src/libsyntax/feature_gate.rs index 129e4a82338..bf6482e5b99 100644 --- a/src/libsyntax/feature_gate.rs +++ b/src/libsyntax/feature_gate.rs @@ -309,6 +309,9 @@ declare_features!
