That means that 0 * Inf = 0. This should be set the same way for an entire pipeline. Note that this applies not only to the literal MUL TGSI opcode, but all FP32 multiplications implied by other operations, such as MAD, FMA, DP2, -DP3, DP4, DST, LOG, LRP, XPD, and possibly others. If there is a +DP3, DP4, DST, LOG, LRP, and possibly others. If there is a mismatch between shaders, then it is unspecified whether this behavior will be enabled. |
