Editing Speculative execution (section)

===Eager execution===
{{See also|Eager evaluation}}

Eager execution is a form of speculative execution where both sides of the conditional branch are executed; however, the results are committed only if the predicate is true. With unlimited resources, eager execution (also known as ''oracle execution'') would in theory provide the same performance as perfect [[branch prediction]]. With limited resources, eager execution should be employed carefully, since the number of resources needed grows [[exponential growth|exponentially]] with each level of branch executed eagerly.<ref name="ŠilcRobič1999">{{cite book|author1=Jurij Šilc|author2=Borut Robič|author3=Theo Ungerer|title=Processor architecture: from dataflow to superscalar and beyond|url=https://archive.org/details/processorarchite0000silc|url-access=registration|access-date=21 January 2011|year=1999|publisher=Springer|isbn=978-3-540-64798-0|pages=[https://archive.org/details/processorarchite0000silc/page/148 148]–150}}</ref>
