static ANTLR3_UINT8 bitIndex [256]
Array of left most significant bit positions for an 8 bit element provides an efficient way to find the highest bit that is set in an n byte value (n>0).
static ANTLR3_UINT64 bitMask [64]
Rather than use the bit index of a trie node to shift 0x01 left that many times, then & with the result, it is faster to use the bit index as an index into this table which holds precomputed masks for any of the 64 bits we need to mask off singly.
Detailed Description
Provides a number of useful functions that are roughly equivalent to java HashTable and List for the purposes of Antlr 3 C runtime.
Also useable by the C programmer for things like symbol tables pointers and so on.

-
- *

Given a starting node, descend its dependent nodes (ones that it has edges to) until we find one without edges. Having found a node without edges, we have discovered the bottom of a depth first search, which we can then ascend, adding the nodes in order from the bottom, which gives us the dependency order.

Add an entry into the INT trie. Basically we descend the trie as we do when searching it, which will locate the only node in the trie that can be reached by the bit pattern of the key. If the key is actually at that node, then if the trie accepts duplicates we add the supplied data in a new chained bucket to that data node. If it does not accept duplicates then we merely return FALSE in case the caller wants to know whether the key was already in the trie. If the node we locate is not the key we are looking to add, then we insert a new node into the trie with a bit index of the leftmost differing bit and the left or right node pointing to itself or the data node we are inserting 'before'.

Array of left most significant bit positions for an 8 bit element provides an efficient way to find the highest bit that is set in an n byte value (n>0). Assuming the values will all hit the data cache, coding without conditional elements should allow branch prediction to work well and of course a parallel instruction cache will whip through this. Otherwise we must loop shifting a one bit and masking. The values we tend to be placing in out integer patricia trie are usually a lot lower than the 64 bits we allow for the key allows. Hence there is a lot of redundant looping and shifting in a while loop. Whereas, the lookup table is just a few ands and indirect lookups, while testing for 0. This is likely to be done in parallel on many processors available when I wrote this. If this code survives as long as yacc, then I may already be dead by the time you read this and maybe there is a single machine instruction to perform the operation. What else are you going to do with all those transistors? Jim 2007
The table is probably obvious but it is just the number 0..7 of the MSB in each integer value 0..256

Rather than use the bit index of a trie node to shift 0x01 left that many times, then & with the result, it is faster to use the bit index as an index into this table which holds precomputed masks for any of the 64 bits we need to mask off singly. The data values will stay in cache while ever a trie is in heavy use, such as in memoization. It is also pretty enough to be ASCII art.
