Errata for Chapter 11

The section about comparisons needs a bit of work. The floating point comparison instructions set different flags than the integer comparisons. Here is the proper set of floating point conditional jump instructions:

instruction	meaning
jb	jump if below
jbe	jump if below or equal
ja	jump if above
jae	jump if above or equal
je	jump if equal
jne	jump if not equal

On page 116 "from" on the first line should be "for".
The comments in the code at the top of page 118, need to use subtract instead of add.
On page 119, on the first line of 11.5.2, remove "double word".
On page 119, second paragraph under 11.5.2, "if implicit" should be "is implicit".
On page 120, I tried to invent the instruction jmple. It should be jbe.
On page 122, replace sqrt in the code with sqrtss.
On page 123, left out the function name for "dot_product".
On page 123, replace "test" with "cmp" in the horner function.
