Summary: glsl compiled wrong
Product: Mesa
Version: git
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Mesa core
AssignedTo: mesa3d-dev@lists.sourceforge.net
ReportedBy: amaasi...@gmail.com
vdrift data/shaders/full/vertex.glsl seems to compile wrong,
I'll attach the shader and output.
from this line:
refmapdir = vec3(gl_TextureMatrix[2] * vec4(reflect(viewdir, normal_eye),0));
reflect(viewdir, normal_eye) sequence starts with:
20: DP3 TEMP[0].w, TEMP[1], TEMP[1];
Seems it's using same register for I and N.
also in the end we output 2 attribs from same temp:
35: MOV OUTPUT[17], TEMP[3];
36: MOV OUTPUT[18], TEMP[3];
