from Timothy Arceri
This is odd. As far as I can tell the shader variant produced =
after loading
from the case is the same as the one produced when the cache is disabled.
Its also a fairly simple program. From tests/texturing/shaders/texelFetch.c=
the
offending program is:
int vs =3D piglit_compile_shader_text(GL_VERTEX_SHADER,
"#version 130\n"
"#extension GL_ARB_explicit_attrib_location: require\n&quo=
t;
"layout(location=3D0) in vec4 pos;\n"
"void main() {\n"
" gl_Position =3D pos;\n"
"}\n");
(void)!asprintf(&fs_code,
"#version 130\n"
"#extension GL_ARB_explicit_attrib_location: require\n&quo=
t;
"#extension GL_ARB_fragment_coord_conventions: require\n&q=
uot;
"uniform int layer;\n"
"uniform int si;\n"
"layout(pixel_center_integer) in vec4 gl_FragCoord;\n"
"layout(location=3D0) out %s o;\n"
"void main() {\n"
" o =3D %s(%sgl_FragCoord.x, gl_FragCoord.y, layer, si);\=
n"
"}\n",
sampler.return_type,
sampler.return_type,
sampler.data_type =3D=3D GL_UNSIGNED_INT ? "" : "=
;-");
We must not be setting a flag somewhere, but I've looked over the code that
handles the cache multiple time now and can't spot any real difference bet=
ween
tgsi and nir.
