We often look at the SIL output of -sil-print-function and may want to debug a specific pass after looking at the output.
-sil-break-before-pass-count=<pass_number> will allow to automatically break in the debugger after <pass_count> of passes are run.
Example:
From -sil-print-function dump:
"SIL function after #6680, stage MidLevel,Function, pass 38: RedundantLoadElimination"
-Xllvm -sil-break-before-pass-count=6680 will break before running this pass in the debugger
