Summary: GLSL struct causing "Invalid src register file ..."
error
Product: Mesa
Version: 7.6
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa3d-dev@lists.sourceforge.net
ReportedBy: brian.h...@gmail.com
GLSL fragment shader is producing this error:
Mesa 7.7.1 implementation error: Invalid src register file 12 in
get_src_register_pointer()
Please report at bugzilla.freedesktop.org
I've reduced the code down as much as I could while still reproducing the bug:
--- shader.frag --------------
uniform sampler3D volShadSampler0;
struct VolShad
{
sampler3D texture;
int samples;
int channels;
mat4 worldToScreen;
};
vec3 testfunc(VolShad vs, vec3 p)
{
return vec3(1.0, 1.0, 1.0);
}
void main()
{
// (Initializing the VolShad struct this way also causes the error)
//VolShad volShad0 = VolShad(volShadSampler0, 8, 3, mat4(0.987538,
0.911446, 0.626908, 0.626908, 0, 2.20361, -0.496881, -0.49688, 1.03169,
-0.872442, -0.600081, -0.600081, -47.4917, 35.4831, 75.2649, 75.3648));
VolShad volShad0;
volShad0.texture = volShadSampler0;
volShad0.texture = 8;
volShad0.channels = 3;
volShad0.worldToScreen = mat4(0.987538, 0.911446, 0.626908, 0.626908, 0,
2.20361, -0.496881, -0.49688, 1.03169, -0.872442, -0.600081, -0.600081,
-47.4917, 35.4831, 75.2649, 75.3648);
vec3 outputColor = testfunc(volShad0, vec3(1, 1, 1));
gl_FragColor = vec4(1, 1, 1, 1);
}
