<div class="moz-cite-prefix">I suppose I was just doing the
"smallest" thing. Disabling the hack entirely also allows it to
build and is probably the correct thing to do. I'm not that
knowledgeable about glibc vs. Bionic differences so the thing to
do would be to test whether those functions work without the
"hack" on Android. Unfortunately at the moment I can't get my
Android JIT test program to actually run; it crashes somewhere in
LLVM without any useful output (the debugger also crashes), so
that one's going to take some time to figure out.<br>

The CMake changes look fine to me, landed in r194051!<br>

As for the JITMemoryManager.cpp changes, not so sure. Did you try
disabling the 'hack' described below instead of patching it?<br>

avoiding open64 which is missing on Android). <br>

Sadly even though it builds I can't get generated code to work -
it appears at the moment that the generated code doesn't have
execute permissions set for some reason (this is 3.3, not svn).
