This only works for vector of rank 1 right? We should probably check and fail for larger ranks?

I don't think this does anything if you don't add -split-input-file to the command line. Also I'm not sure you need it for this file?

Good catch, thanks!

Sorry, I missed the flag. I thought we were modernizing some of these old tests and adding -split-input-file to them because there was some benefit in doing so. Isn't that the case? Isn't each chunk processed in parallel? (Probably not because lit tests already run in parallel...). Please, let me know! I would be interested in knowing the actual purpose of this flag! I'll remove it if there is no actual benefit. Thanks!

This flag will make each function processed in an isolated module.
This is useful in many cases:

• expected failures: you want to check diagnostics, but you still want to check all the functions and not stop on the first error
• you can reuse the same name for multiple functions in the same file
• some test are sensitive to the environment in the module, that make each "conceptual test" in the file "isolated" from each other.
• a new context will be used ensure no "pollution" of the environment in between each split "test"
