I messed with how memcmp works, trying a couple of different things like
comparing shorts and integers instead of chars (x86 allows unaligned
access w/penalty). All work slightly slower than just comparing chars.
I believe the memcmp is slower because it moves the chars from immediate
operands to another memory reference. How's this for a compromise, not
quite as pretty, but still somewhat readable:
! if (memcmp(CUR_PTR, "<!DOCTYPE", 9) == 0)
---
! if (CMP9(CUR_PTR, '<', '!', 'D', 'O', 'C', 'T', 'Y', 'P', 'E'))
Okay, this is better than the original solution, applied and commited,
thanks !
