Supersedes D80225. Add --ld-path= to avoid strange target specific prefixes and make -fuse-ld= focus on its intended job: "linker flavor". (-f* affects generated code or language features. --ld-path does not affect codegen, so it is not named -f*) The way --ld-path= works is similar to "Command Search and Execution" in POSIX.1-2017 2.9.1 Simple Commands. If --ld-path= specifies * an absolute path, the value specifies the linker. * a relative path without a path component separator (/), the value is searched using the -B, COMPILER_PATH, then PATH. * a relative path with a path component separator, the linker is found relative to the current working directory. -fuse-ld= and --ld-path= can be composed, e.g. `-fuse-ld=lld --ld-path=/usr/bin/ld.lld` The driver can base its linker option decision on the flavor -fuse-ld=, but it should not do fragile flavor checking with --ld-path=.

This test serves two purposes:
|
|
|
|
(1) It documents all existing warnings that currently have no associated -W flag,
|
|
and ensures that the list never grows.
|
|
|
|
If you take an existing warning and add a flag, this test will fail.
|
|
To fix this test, simply remove that warning from the list below.
|
|
|
|
(2) It prevents us adding new warnings to Clang that have no -W flag. All
|
|
new warnings should have -W flags.
|
|
|
|
If you add a new warning without a flag, this test will fail. To fix
|
|
this test, simply add a warning group to that warning.
|
|
|
|
|
|
The list of warnings below should NEVER grow. It should gradually shrink to 0.
