MSDN states that the source parameters can have swizzles and
modifiers. Unless, you can prove that's not true, the code should

void pshader_glsl_bem(SHADER_OPCODE_ARG* arg) {
    glsl_src_param_t src0_param, src1_param;

    shader_glsl_append)dst(arg->buffer, arg);
    shader_glsl_add_src_param(arg, arg->src[0], arg->src_addr[0],
    shader_glsl_add_src_param(arg, arg->src[1], arg->src_addr[1],
    shader_addline(arg->buffer, "%s + bumpenvmat * %s);\n",
src0_param.param_str, src1_param.param_str);

Normally you would have to take the destination write mask into
account as well, but for this instruction it's always .xy.
