cmd/compile: use expandable columns in ssa.html? #25286
As the number of SSA passes has grown, ssa.html has gotten wider and thus harder to navigate. I'd like to float the idea of having the initial display show just a few columns, with the others be expandable stubs (with names). As to the initial list of columns, maybe something like: start, after early deadcode, after opt, after lower, after late deadcode, after regalloc, genssa.
Yes. It’d be nice to do some saved local state or query params, but as a first pass, I think always reverting to the default is fine. In the normal case I imagine the reader will be interested in one or two columns at most, so restoring state manually isn’t that big a deal.
In case if you want to give a feedback without downloading the patch above:
The vertical text (a column) can be expanded by clicking on it. If you want something else, just let me know.
I would be glad to help because I learned a thing or two about SSA while making the change. Also I would like to implement some of the TODOs buired in ssa.go regarding graphic representation (nodes->ssa?) or maybe just dumping the log from ssa to the ssa.html, so file can be shared as standalone piece.
EDITED: typos and formatting
