Hi Jiangning,

This commit that you requested be merged into the 3.4 branch has caused a regression in
the MultiSource/Applications/sgefa test:

-----------------------------------------------------------------------

 Merging r198940:
    
    ------------------------------------------------------------------------
    r198940 | kristof.beyls | 2014-01-10 08:44:34 -0500 (Fri, 10 Jan 2014) | 2 lines
    
    Enable -fuse-init-array for all AArch64 ELF targets by default, not just linux.

I have reverted this in the 3.4 branch, I'm guessing I merged this wrong. Here was
my original attempt: https://github.com/llvm-mirror/clang/commit/dce55aa1d529e1a07f41241c6a54b9570e0cec64
Can you merge  r198940 into 3.4 and send me the correct patch.

Thanks,
Tom
