Hello,
In 'SSA Operands' node, tree-ssa.texi, the original text are
"
For instance, given
@smallexample
@{
int a, b;
a = b

@code{a = b} will have one real definition and one real use because
variable @code{b} is completely modified with the contents of
variable @code{a}. Real definition are also known as @dfn{killing
definitions}. Similarly, the use of @code{a} reads all its bits.

I think it's a mistake between a and b. It should be,

variable @code{a} is completely modified with the contents of
variable @code{b}. Real definition are also known as @dfn{killing
