Robin Morisset 7114ac8258 [X86] Allow atomic operations using immediates to avoid using a register ... The only valid lowering of atomic stores in the X86 backend was mov from register to memory. As a result, storing an immediate required a useless copy of the immediate in a register. Now these can be compiled as a simple mov. Similarily, adding/and-ing/or-ing/xor-ing an immediate to an atomic location (but through an atomic_store/atomic_load, not a fetch_whatever intrinsic) can now make use of an 'add $imm, x(%rip)' instead of using a register. And the same applies to inc/dec. This second point matches the first issue identified in http://llvm.org/bugs/show_bug.cgi?id=17281 llvm-svn: 216980		2014-09-02 22:16:29 +00:00
