Abstract
Techniques for achieving coherence between dynamically optimized code and original code are disclosed. In an embodiment, a search is performed for a first entry for a first page containing a first code region in a first data structure. The first code is used to determine whether a first indicator in the first entry is set to a first value. The first entry is added to the first data structure, in response to failing to find the first entry in the first data structure. A second search may be performed for a second entry for the first code region in a second data structure, in response to determining that the first indicator is set to the first value. Other embodiments are also disclosed and claimed.
