[llvm-commits] [PATCH] Fix ARM MCJIT icache invalidation

[Amara Emerson]

Ping. Jim, could you take a look at this? There was a patch for review a
while ago which may conflict with this one (refactoring parts of lli and
adding MCJIT tests).

This bug is causing severe problems on ARM.

Hi,

I've fixed a bug in lli/MCJIT which causes the icache invalidation to have
no effect, causing segfaults on ARM. This patch affects the MCJIT and the
memory manager interfaces. Icache invalidation is now called by default in
MCJIT instead of explicitly in lli.

This fixes random segfaults in ExecutionEngine/MCJIT/test-common-symbols.ll
(and it seems other ARM MCJIT failing tests as well).

Regards,
Amara
