Crate run_make_support

run-make-support is a support library for run-make tests. It provides command wrappers and convenience utility functions to help test writers reduce duplication. The support library notably is built via cargo: this means that if your test wants some non-trivial utility, such as object or wasmparser, they can be re-exported and be made available through this library.

Modules

• cc
• clang
• command 🔒
• diff
• drop_bomb 🔒
  This module implements “drop bombs” intended for use by command wrappers to ensure that the constructed commands are eventually executed. This is exactly like rustc_errors::Diag where we force every Diag to be consumed or we emit a bug, but we panic instead.
• fs_wrapper
• llvm_readobj
• run
• rustc
• rustdoc

Macros

• impl_common_helpers 🔒
  Implement common helpers for command wrappers. This assumes that the command wrapper is a struct containing a cmd: Command field. The provided helpers are:

Functions

• assert_not_contains
  Check that haystack does not contain needle. Panic otherwise.
• bin_name
  Construct the binary name based on platform.
• copy_dir_all
  Copy a directory into another.
• cwd
  Return the current working directory.
• cygpath_windows
  Use cygpath -w on a path to get a Windows path string back. This assumes that cygpath is available on the platform!
• dynamic_lib_extension
• dynamic_lib_name
  Construct the dynamic library name based on the platform.
• env_var
• env_var_os
• handle_failed_output 🔒
• htmldocck
• is_darwin
  Check if target uses macOS.
• is_msvc
  Check if target uses msvc.
• is_windows
  Check if target is windows-like.
• path
  Returns the path for a local test file.
• python_command
• read_dir
• recursive_diff
  Check that all files in dir1 exist and have the same content in dir2. Panic otherwise.
• run_in_tmpdir
  This function is designed for running commands in a temporary directory that is cleared after the function ends.
• rust_lib_name
  Generate the name a rust library (rlib) would have.
• set_host_rpath
  Set the runtime library path as needed for running the host rustc/rustdoc/etc.
• source_root
  Path to the root rust-lang/rust source checkout.
• static_lib_name
  Construct the static library name based on the platform.
• target
  TARGET
• uname
  Run uname. This assumes that uname is available on the platform!
