2ca6d2a325 Refactor splitOn and make it fuse 2020-11-08 16:02:05 +05:30
Harendra Kumar
924d78e8e6 Use a recursive local loop inside step function 
Though now, the loop does not fuse and earlier it fused completely. The
fused loop is much more inefficient.

Improves the performance by 3x, possibly due to less amount of state
being threaded around the loop.

a2a589e54e Use strictness annotation on ring head pointer 
The ring head Ptr was being allocated in the loop causing 16x
allocations compared to when strictness annotation is used.

c54581ee95 Improve performance of parseMany 
1. Make the parser state strict so that it can fuse.
2. Use special paths for "Continue 0" and "Done 0" cases

Overall improvement from 440 us (6GB allocations) to 175 us (22 MB
allocations).

a94ec3688e Use NoSpecConstr annotation on the list type 
This is to avoid too many recursive specializations (because we use
-fspec-constr-recursive=16) on the list argument in parselMx', leading
to huge code bloat in the core and requiring a lot of memory to compile.
