Problem: `FILECHECK_OPTS` was implemented so that a test runner, such as a bot, can specify FileCheck debugging options, such as `-dump-input=fail`. However, some existing test suites have FileCheck calls that already specify `-dump-input=fail` or `-dump-input=always`. Without this patch, such tests fail under such a test runner because FileCheck doesn't accept multiple occurrences of `-dump-input`. Solution: This patch permits multiple occurrences of `-dump-input` by assigning precedence to its values in the following descending order: `help`, `always`, `fail`, and `never`. That is, any occurrence of `help` always obtains help, and otherwise the behavior is similar to `-v` vs. `-vv` in that the option specifying the greatest verbosity has precedence. Rationale: My justification for the new behavior is as follows. I have not experienced use cases where, either as a test runner or as a test author, I want to **limit** the permitted debugging verbosity (except as a test author in FileCheck's or lit's test suites where the FileCheck debugging output itself is under test, but the solution there is `env FILECHECK_OPTS=`, and I imagine we should use the same solution anywhere else this need might occur). Of course, as either a test runner or test author, it is useful to **increase** debugging verbosity. Reviewed By: probinson Differential Revision: https://reviews.llvm.org/D70784 |
