Also move the FIXME to the source code to avoid duplication, and also suppress harmless warnings that are annoying when you compile manually.

//! Regression test for <https://github.com/rust-lang/rust/issues/33013>.

// === LLDB TESTS ==================================================================================
|
|
|
|
// Unlike gdb, lldb will display 7 lines of context by default. It seems
|
|
// impossible to get it down to 1. The best we can do is to show the current
|
|
// line and one above. That is not ideal, but it will do for now.
|
|
//@ lldb-command: settings set stop-line-count-before 1
|
|
//@ lldb-command: settings set stop-line-count-after 0
|
|
|
|
//@ lldb-command: run
|
|
// In `breakpoint_callback()` in `./src/etc/lldb_batchmode.py` we do
|
|
// `SetSelectedFrame()`, which causes LLDB to show the current line and one line
|
|
// before (since we changed `stop-line-count-before`). Note that
|
|
// `normalize_whitespace()` in `lldb_batchmode.py` removes the newlines of the
|
|
// output. So the current line and the line before actually ends up on the same
|
|
// output line. That's fine.
|
|
//@ lldb-check: [...]let mut c = 27;[...]
|
|
//@ lldb-command: next
