Hello,

In 'SSA Operands' node, tree-ssa.texi, the original text are

"
For instance, given

@smallexample
@{
  int a, b;
  a = b
@}
@end smallexample

Since @code{a} and @code{b} are non-aliased locals, the statement
@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
definitions}.  Similarly, the use of @code{b} reads all its bits.
