#version 130 case statements are mishandled

[CliveMcCarthy]

The optimized output from a case statement is missing an 'if' and sequential assignments have commas missing.

Here is a typical output for a case:

bool tmpvar_3;
tmpvar_3 = bool(0);
bool tmpvar_4;
tmpvar_4 = bool(0);
(918 == style) tmpvar_3 = bool(1);
tmpvar_4 tmpvar_3 = bool(0);
if (tmpvar_3) {
float angle_5;
angle_5 = -(rotation_radians);
float tmpvar_6;
tmpvar_6 = cos(angle_5);
float tmpvar_7;
tmpvar_7 = sin(angle_5);
vec2 tmpvar_8;
tmpvar_8.x = tmpvar_6;
tmpvar_8.y = tmpvar_7;
vec2 tmpvar_9;
tmpvar_9.x = -(tmpvar_7);
tmpvar_9.y = tmpvar_6;
mat2 tmpvar_10;
tmpvar_10[0u] = tmpvar_8;
tmpvar_10[1u] = tmpvar_9;
vec3 tmpvar_11;
tmpvar_11.xy = (normal_2.xy * tmpvar_10);
tmpvar_11.z = normal_2.z;
vec3 tmpvar_12;
tmpvar_12 = normalize(diffuse_direction);
vec3 I_13;
I_13 = -(tmpvar_12);
color_1.xyz = (((ads_lighting.x * input_color.xyz) + (
(ads_lighting.y * max (dot (tmpvar_11, tmpvar_12), 0.0))
* input_color.xyz)) + ((ads_lighting.z *
pow (max (0.0, (I_13 - (2.0 *
(dot (tmpvar_11, I_13) * tmpvar_11)
)).z), 128.0)
) * vec3(1.0, 0.945, 0.878)));
tmpvar_4 = bool(1);
};
