[PATCH] D82203: [FileCheck] Implement -dump-input-context, and default to 5

[Joel E. Denny via Phabricator via llvm-commits]

jdenny added a comment.

I'm thinking there could also be a `-dump-input-filter` command-line option to describe what lines of input should be sought, and `-dump-input-context` would describe how much context around those lines should be printed.  It might have values like:

- `all`: include all input lines.  The effect is to disable `-dump-input-context`.  This is probably best for CI.
- `annotation`: include only input lines with annotations.
- `error`: include only input lines with error diagnostics. This is very nearly what this patch implements now.  It would probably be the default.
- `input`: include only raw input lines and no annotations so you can more easily try that exact input again with FileCheck.  This also would disable `-dump-input-context`.
