Description

Remark: useless/misleading //@ run-pass in a few aux files that are //@ ignore-test (//@ ignore-auxiliary)

Originally posted by @jieyouxu in https://github.com/rust-lang/rust/pull/139967#discussion_r2048970713

Consider rejecting combination of

  • Conditional test execution directives (e.g. //@ ignore-*), with
  • Unconditional test execution directives (e.g. //@ ignore-test),

Since the unconditional test ignore will "absorb" conditional ones. Probably do this after reworking directive handling.

Research direction

Start by reading compiletest's directive handling, especially how conditional directives such as //@ ignore-* interact with unconditional directives such as //@ ignore-test and //@ ignore-auxiliary. Done should include rejecting combinations where an unconditional directive absorbs a conditional one, while accounting for the planned directive-handling rework.
