- // This test case tests the incremental compilation hash (ICH) implementation
- // for inline asm.
- // The general pattern followed here is: Change one thing between rev1 and rev2
- // and make sure that the hash has changed, then change nothing between rev2 and
- // rev3 and make sure that the hash has not changed.
- // build-pass (FIXME(62277): could be check-pass?)
- // revisions: cfail1 cfail2 cfail3 cfail4 cfail5 cfail6
- // compile-flags: -Z query-dep-graph -O
- // needs-asm-support
- // [cfail1]compile-flags: -Zincremental-ignore-spans
- // [cfail2]compile-flags: -Zincremental-ignore-spans
- // [cfail3]compile-flags: -Zincremental-ignore-spans
- // [cfail4]compile-flags: -Zincremental-relative-spans
- // [cfail5]compile-flags: -Zincremental-relative-spans
- // [cfail6]compile-flags: -Zincremental-relative-spans
