The compile-flags system is pretty cool! 😃 I have uploaded a new patch with a test. Note: I removed the "ar"/archiver-specific changes because I could not find a way to trigger the "could not exec the archiver" error. |

There was a problem hiding this comment.
Huh, I was unaware that this was even possible to name the return type! This would all look nicer as:
let opt_prog = {
let _g = io::ignore_io_error();
run::process_output(cc, args)
};Trap the io_error condition so that a more informative error message is displayed when the linker program cannot be started, such as when the name of the linker binary is accidentally mistyped. closes rust-lang#10755

…ednet new lint `legacy_numeric_constants` Rework of rust-lang#10997 - uses diagnostic items - does not lint imports of the float modules (`use std::f32`) - does not lint usage of float constants that look like `f32::MIN` I chose to make the float changes because the following pattern is actually pretty useful ```rust use std::f32; let omega = freq * 2 * f32::consts::PI; ``` and the float modules are not TBD-deprecated like the integer modules. Closes rust-lang#10995 --- changelog: New lint [`legacy_numeric_constants`] [rust-lang#12312](rust-lang/rust-clippy#12312)
