1.17.0 powerpc64le test failure: compile-fail/asm-src-loc.rs

[infinity0]

Due to #42476 and #39015 I am now passing --disable-optimize-tests to ./configure. But now I get a test failure:

error: /home/infinity0/upstream/rustc-1.17.0+dfsg2/src/test/compile-fail/asm-src-loc.rs:1: unexpected "error": '1:1: 1:1: <inline asm>:1:2: error: unrecognized instruction mnemonic'

not found errors (from test file): [

        msg: "instruction"
    }
]

For reference, this is the test.

I am in a dilemma because I don't know the best way forward now. If I give:

• none of the below flags to ./configure, I get 1.14.0 powerpc64le test failures: smoke_dtor, test_typed_arena_drop_small_count #39015
• --disable-optimize, I get 1.17.0 powerpc64le: "LLVM ERROR: Undefined temporary symbol" after disabling optimisation #42476
• --disable-optimize-tests, I get this bug.

I could ignore the test on ppc64el but it seems quite important, is there a way to patch rust to fix it instead?

from testing in rust.godbolt.org this appears to be fixed on nightly

I would have thought this would have found the error correctly because it emitted an error containing the phrase "instruction"... nonetheless, this test was for a now-deprecated form of inline assembly that we don't support. Thank you Jake for the followup. Between these facts, this should not be an issue anymore. Closing.
