#2782: Cache
 Reporter:  ppisa     |      Owner:
     Type:  defect    |     Status:  new
 Priority:  high      |  Milestone:  4.11
Component:  libdl     |    Version:  4.11
 Severity:  critical  |   Keywords:
 Cache manager for ARM and libdl RTL for most of architectures are broken
 for 4.11 branch.

 The reason is that instruction cache has to be invalidated for most cache
 enabled architectures after code modifications because local L1
 instruction caches is not included in data cache synchronization

 Affected architectures are ARM, probably most of PowerPC, SPARC, MIPS.
 Not affected x86 which solve even instruction cache synchronization on
 hardware level.
