branching splits

Branching logic:

getSplits:
	list[]

	for pointer in splits:
		if pointer had a condjump/altbranch in branches:
			continue until pointer is of condjump/altbranch

		if branch of pointer is in branches:
			add pointer to list

	return list

on init:
	branches = [A]
	list = getSplits()
	curSplit = 0
	prevalt = null

on nextsplit:
	skip to list[++cursplit]
	prevalt = null

on switch branch:
	if split had a altbranch:
		prevalt = split
		add altbranch to branches
		list = getSplits()
		skip to list[curSplit]

	else if prevalt != null:
		remove branch of prevalt from branches
		prevalt = null
		list = getSplits()
		undosplit to list[curSplit]

on display:
	display list




alternate method:

on init:
	branches = [A]
	prevsplit = firstsplit

on nextsplit:
	prevsplit = split

	if split has a condjump and branchcond is in branches:
		skip to the next split of branchcond
	else
		skip to next split of any in branches

on switch branch:
	if split had a altbranch:
		prevsplit = split
		skip to next split of branchcond
		add altbranch to branches
	else if prevsplit had a altbranch and split is of altbranch:
		undosplit to prevsplit
		remove altbranch from branches

on display:
	list[]

	for pointer in splits:
		if pointer had a condjump/altbranch in branches:
			continue until pointer is of condjump/altbranch

		if pointer.branch is in branches:
			add pointer to list

	display list
