Allow more atomic instructions to use untyped pointer as an operand (SPV_KHR_untyped_pointers extension) #292
Description
Should OpAtomicFAddEXT, OpAtomicFMinEXT, and OpAtomicFMaxEXT atomic instructions be also allowed to be used with SPV_KHR_untyped_pointers extension?
The main point is that these instructions do have a return type which can be used to interpret untyped pointer argument.
This will require modifications to SPV_EXT_shader_atomic_float_min_max, SPV_EXT_shader_atomic_float_add, and its 16-bit version.
