[Bug 102382] New: nv50ir: isImmediate doesn't properly work for integers if Value is typed as float
...rc/gallium/drivers/nouveau/codegen/nv50_ir_lowering_nvc0.cpp#n140
the isInteger(0) call assumes the Value being a F32, which leads to a is
2.8E-45 == 0 check returning true resulting into the lod argument being removed
from texfetch.
This causes a fail in the KHR-GL44.robust_buffer_access_behavior.texel_fetch
CTS test.
Other isInteger calls might be broken as well where an immediate of type float
is interpreted as int by the instruction.
