The current dumping format consists of 1 row of information per function. This
will become unweildy to write patterns for when I add additional state to
FunctionInfo.
Instead, this commit converts the dumping format of the caller analysis into a
multi line yaml format. This yaml format looks as follows:
---
calleeName: closure1
hasCaller: false
minPartialAppliedArgs: 1
partialAppliers:
- partial_apply_one_arg
- partial_apply_two_args1
fullAppliers:
...
This can easily expand over time as we expand the queries that caller analysis
can answer.
As an additional advantage, there are definitely yaml parsers that can handle
multiple yaml documents in sequence in a stream. This means that by running via
sil-opt the caller-analysis-printer pass, one now will get a yaml description of
the caller analysis state, perfect and ready for analysis.
