/* The printf test functions take a format argument from the test data
|
|
* for several reasons:
|
|
* - For some tests, it makes sense to vary the format.
|
|
* - For all tests, it means we're testing the actual printf function
|
|
* that parses the format at runtime, and not a compiler optimization.
|
|
* (It may be useful to add tests that allow compiler optimizations.
|
|
* There aren't any yet at the time of writing.)
