What a timing. I am working on (slowly) on a tool that would
get all struct and class declarations and for each of them get
functions in which they are used. Then combine them with
profiling data to find data structures that are hot and how
changing them affects performance. The only code that is
written is partially parsing perf.data file and the rest is
missing. It would be wonderful if your tool could emit such
functions then my job would be easy. Parsing would have been
done if perf.data format was fully documented.
Something like "find all references"?
Late response is better than none i guess. References are bad
word because it could mean references as passed to functions or
pointers. What I am looking is occurrences in functions. Whether
class/struct is created or passed trough pointer I want to know
about it. If class/struct is put into container I want to track
that as well. I want to know all uses of that data type.
One frequent thing people say on reddit is that phobos is based
on GC. It would be nice if there was a tool that could report
what percentage of functions actually use GC and what are marked
as @nogc
