[Mesa-dev] nir warnings

[Brian Paul]

There's a number of new compiler warnings (gcc 4.8.2) in the nir code:

nir/glsl_to_nir.cpp: In member function 'virtual void 
{anonymous}::nir_visitor::visit(ir_call*)':
nir/glsl_to_nir.cpp:610:73: warning: 'op' may be used uninitialized in 
this function [-Wmaybe-uninitialized]
        nir_intrinsic_instr *instr = nir_intrinsic_instr_create(shader, op);
                                                                          ^
nir/nir_lower_phis_to_scalar.c: In function 'is_phi_src_scalarizable':
nir/nir_lower_phis_to_scalar.c:70:14: warning: 'or' of unmatched 
not-equal tests is always 1 [enabled by default]
               src_alu->op != nir_op_vec4;
               ^
nir/nir_lower_samplers.cpp: In function 'void 
lower_sampler(nir_tex_instr*, gl_shader_program*, const gl_program*, 
void*)':
nir/nir_lower_samplers.cpp:72:9: warning: unused variable 'has_indirect' 
[-Wunused-variable]
     bool has_indirect = false;
          ^

Wondering if someone can clean those up.
