Rollup merge of #42225 - brson:vs2017, r=alexcrichton
Support VS 2017 Fixes #38584 This replaces all the MSVC linker logic with that from the 'gcc' crate. The code looks the same, but there could be regressions. I've only tested this with x86_64. r? @alexcrichton cc @vadimcn @retep998

|
|
||||||
//!
|

//! This module contains a cross-platform interface but has a blank unix
|
|
||||||
//! implementation. The Windows implementation builds on top of Windows native
|
|
||||||
//! libraries (reading registry keys), so it otherwise wouldn't link on unix.
|
|
||||||
//!
|
|
||||||
//! Note that we don't have much special logic for finding the system linker on
|
|
||||||
//! any other platforms, so it may seem a little odd to single out MSVC to have
|
|
||||||
//! a good deal of code just to find the linker. Unlike Unix systems, however,
|
|
||||||
//! the MSVC linker is not in the system PATH by default. It also additionally
|
|
||||||
//! needs a few environment variables or command line flags to be able to link
|
|
||||||
//! against system libraries.
|
|
||||||
//!
|
|
||||||
//! In order to have a nice smooth experience on Windows, the logic in this file
|
|
||||||
//! is here to find the MSVC linker and set it up in the default configuration
|
|
||||||
//! one would need to set up anyway. This means that the Rust compiler can be
|
|
||||||
//! run not only in the developer shells of MSVC but also the standard cmd.exe
|
|
||||||
//! shell or MSYS shells.
|
|
||||||
//!
|
|
||||||
//! As a high-level note, all logic in this module for looking up various
|
|
||||||
//! paths/files is based on Microsoft's logic in their vcvars bat files, but
|
|
||||||
//! comments can also be found below leading through the various code paths.
