[llvm-commits] [PATCH] Enable atomic64 min/max operations on ARM

[Silviu Baranga]

Hi,

The attached patch implements code generation for atomic64 min/max/umin/umax
Operations for ARM. The patch extends the functionality of the
EmitAtomicBinary64
Function to achieve this.

The compare operation needed to implement this is done using sub/sbc
instructions, in order to unify the signed and unsigned cases.

The patch also adds tests for all the implemented operations.

Please review!

Thanks,
Silviu
