I'll take a look.

Change https://go.dev/cl/688856 mentions this issue: cmd/compile/internal/ssa: restrict architectures for TestDebugLines_74576

[gopherbot]

Sorry, but there were parse errors in the watch flakes script.
The script I found was:

#!watchflakes
post <- pkg == "cmd/compile/internal/ssa" && test ~ "TestDebugLines_74576/i74576?.go"

And the problems were:

script:2.53: ~ requires backquoted regexp

See https://go.dev/wiki/Watchflakes for details.

The post-submit build for the gotip-linux-riscv64 builder on https://build.golang.org for https://go.dev/cl/688856 is still running, but looks like the test in question for this issue has passed there:

ok  	cmd/compile/internal/ssa	229.244s

It looks like that build is going to be ultimately reported as failing due to an ASAN issue, but that was happening before and presumably unrelated (and probably tracked by watchflake issue #73979).
