Bug ID: 15357
Summary: MCJIT should not automatically apply relocations to
generated code
Product: libraries
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Generic Execution Engine Support
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
Currently, the MCJIT execution engine attempts to apply relocations to
dynamically generated code as soon as the code has been generated. While this
behavior should be harmless if all other components are behaving correctly, it
is undesirable.
In particular, when code is being generated for remote execution (either in an
external process or on a physically remote system) the client code will likely
want to provide new load addresses for the generated object image sections
before relocations are applied. Intermediate application of relocations is
unnecessary and has been known to cause failures that would otherwise have been
avoided.
