[llvm-commits] [llvm] [Patch] Add RuntimeDyld.invalidateEmittedSectionsCache()

[Danil Malyshev]

Hi,

Please review changed the patch.
This patch adds finalize() to RTDyldMemoryManager, and implements it for MCJITMemoryManager as invalidate instruction cache.


Regards,
Danil

Hi Danil,

That's not the RuntimeDyld's job. That functionality belongs in elsewhere, probably in the client's memory manager implementation where it's hooked into copying the compiled code into the target's address space. For a hosted platform, something similar just w/o the copying.

Hi everyone,



Please review attached the patch.
This patch adds invalidateEmmittedSectionsCache() to the RuntimeDyld and uses it in the MCJIT after resolve relocations.
The MCJIT works unstable on the ARM platforms without it.
This patch haven't any tests because I want to commit the common ExecutionEngine/MCJIT tests after attached the patch will be committed. These tests will cover it.
Regards,
Danil
