- * Two optimization notes on the choice of instructions:
- *
- * The first instruction uses a 16-bit address, which costs an extra,
- * unpairable cycle. This is cheaper than doing a 32-bit access and
- * zeroing the high word, due to the 3-cycle misalignment penalty which
- * would occur half the time. This also turns out to be cheaper than
- * doing two separate 8-bit accesses, as the memory is so rarely in the
- * L1 cache.
- *
- * The window buffer, however, apparently spends a lot of time in the
- * cache, and so it is faster to retrieve the word at the end of the
- * match string with two 8-bit loads. The instructions that test the
- * word at the beginning of the match string, however, are executed
- * much less frequently, and there it was cheaper to use 16-bit
- * instructions, which avoided the necessity of saving off and
- * subsequently reloading one of the other registers.

+ * The first instruction uses a 16-bit address, which costs an extra,

+ * zeroing the high word, due to the 3-cycle misalignment penalty which
+ * would occur half the time. This also turns out to be cheaper than
+ * doing two separate 8-bit accesses, as the memory is so rarely in the
+ * L1 cache.
+ *
+ * The window buffer, however, apparently spends a lot of time in the
+ * cache, and so it is faster to retrieve the word at the end of the
+ * match string with two 8-bit loads. The instructions that test the
+ * word at the beginning of the match string, however, are executed
+ * much less frequently, and there it was cheaper to use 16-bit
+ * instructions, which avoided the necessity of saving off and
+ * subsequently reloading one of the other registers.
