[PATCH] D40385: [mips][compiler-rt] Provide 64bit atomic add and sub

[Kostya Serebryany via Phabricator via llvm-commits]

kcc added a comment.

This change introduces more ifdefs to this file, which is bad. 
It already has one ifdef -- and that one is already for "defined(_MIPS_SIM)"
Please don't introduce any more ifdefs, instead please add a new file (something_something_mips.h) and remove the only ifdef from here.
